• what are interactive environments
• how to classify interactive environments
• interactivity in online communities
• the future of interactive environments
• interaction design

At the end we we’re supposed to write a summary and create a graph of the interactive environments classification. My paper can be found here: “Interactive environments” (PDF).

Accessibility needs

In general we may divide disabilities into 2 categories: technical and physical.

Technical issues

• Browser - browsers may read HTML and CSS differently (especially if it has not been written according to W3C standards)
• Connection speed - visitors should access the web with any connection speed
• Scripts - the website has to remain usable, if scripts (like JavaScript) are disabled
• Mobile devices - a website should have a version for mobile devices, that don’t support the same screen resolutions and standards like desktops do. This issue should be taken into consideration very seriously as the mobile segment is growing fast.

Users with disabilities

• Blind users - the screen reader should understand the webpage, so it would be able to read the content of the web
• Deaf users - for any multimedia materials with audio, the explanations should be given
• Color blindness - the color combinations on the page should not mislead color-blind visitors
• Mobility problems - as some users are not able to use the mouse, the website has to be navigatable without a mouse
• Learning disabilities - users with learning disabilities may find confusing working on certain types of information.

According to these needs, special software has been developed: for blind users, talking browsers read the content of the web. Some websites offer a low vision version of the content and the controls to change the size and colors of the text. It’s important to allow to disable the images and banners and to change the layout of the page. Additionaly, services have been created that allow people with disabilities to use the web via proxy servers (Richards, J. T. et al, 2004). The idea is to provide a software that automatically modifyes the webpage according to the visitor’s needs and disabilities.

SEO creates accessible web

The goal of accessibility is to make web accessible to as many people as possible, despite of their technical, physical or other restrictions. Now, lets think a search engine as a visitor of a site: a search engine can not anyhow “see” the images and “listen” to the audio files on websites. A search engine couldn’t understand the content of the website, if it hasn’t been made accessible. Search engine optimization (SEO) is a term for making search-engine-friendly websites. In other words, it helps us to understand the need for accessible websites. If a webpage is search-engine-friendly, it means it could be also much easily understood by people with disabilities.

Every website should follow some basic SEO principles:

• understandable text links should be used (if you want to link to a page about semantic web, don’t name the link “click here”, but name it “semantic web”)
• tags should indicate the characteristics of a document (type, language etc)
• website should be usable when scripts (like JavaScript) are disabled
• text should be written in clearest and simplest language
• sitemaps and static links to every page
• accurate alt tags etc

Implementing SEO takes us one step closer to accessible web.

Accessibility and usability

The web usability guru Jakob Nielsen states that accessibility is not enough. I agree. Yes, we may build websites that are designed according to all WAI standards, but when the usability of the site is poor, visitors will be still misleaded and they will not start using the website. If a website is designed, both the accessibility and usability factors should be considered.

“When you want to improve your website for users with disabilities, remember the real goal: to help them better use the site” (Nielsen, 2005).

The future

All the fancy applications and web 2.0 services require the second version of the web content accessibility guidelines (WCAG 2.0). Web 2.0 keywords like AJAX and “user generated content” kill the accessible web. A lot of AJAX applications have been built that are not understandable for screen readers and not usable for keyboard-only users. Yes, they look nice, but if the JavaScript has been disabled or the user won’t understand the content, the website will be useless. A simplified and accessible solutions should be available as alternatives.

The problem with user generated content is that the users who provide all the content won’t add alternative text for images and videos so the materials could be accessible for disabled visitors. As these sites usually generate huge numbers of visitors, the site itself can’t guarantee accessible content everywhere.

In order to keep the new web accessible, the guidelines need to be improved.

Accessible websites?

Now, take the accessibility validator and try to find a website that does not generate errors. Even Google.com will generate one accessibility error.

Let’s define the IA

Some definitions that could clear us what information architectures are all about:

• The art and science of organizing and labeling web sites, intranets, online communities and software to support findability and usability. (Information Architecture Institute)
• How the information (text, images, menus etc) is structured on a website and if it flows and reads nicely. (Web Design & Life)
• The design, including organization, labeling, and navigation, of systems that help people share information. (Microsoft Development Center)

As we can see IA’s are used to structure the data and what’s most important - it must be done in a way that it would be as usable as possible. As the flow of information increases constantly, IA’s play a huge role in the whole design process.

Effective IA must reflect the way people think. (Barker, 2005)

Developing the IA

During our Interface and Interaction Design course (lectured by Hans Põldoja), we we’re designing a web 2.0 application with some social-networking flavor. Our idea was to design a site about finding good, but cheap eating-places and trustful hostels to stay. Just like creating your personal travel-plan in the net.

Although the course was quite short, we started from scratch and even ended up with some code-writing. Ofcourse, working on the IA was the most complicated process, because as we were developing the system, we continously came out with new ideas and ways how to improve the application. The IA was changed quite often.

The IA development will start with a in-depth analysis in order to find the requirements. Also analysing the competitors and already existing solutions is very useful - you can find the good-practices how to solve common situations and take notice of the things that have been designed badly and could be done better.

Writing personas can help the developers to understand the target-group of the application and scenarios tell us about the functionality of the systems. It is important to analyse personas and scenarios just to get an overview of the whole system. Later, it is a good idea to hold some interviews with experts in order to ask feedback (if the scenarios make sense, if they are understandable, how they could be improved etc).

Card sorting

In our course, the next thing we did, was writing down all the functionalities the site must contain. Later, we were categorizing them and it became the basis of the IA. And that is what card sorting is generally all about.

Card sorting is a user-generated inexpensive and quick design method for increasing the system’s findability. The process involves sorting a series of cards, each labeled with a piece of content or functionality, into groups that make sense to users. (Barker, 2005)

Finding the right categories was not easy - as the front page of the site should be as simple as possible, then we wanted to cut down the number of links. Finally, we managed to divide all the labels under 3 main categories and I can say that finding the right names for them can be quite complicated. After making the first versions, always ask feedback if the structure does make sense and if people who will start using the system do think the same way you did.

We used the structure as the basis and draw the first version of the IA, which was later, after several improvements, used in creating the prototypes and simple HTML-pages.

Conclusion

Designing the IA is the most important part in the whole design process - only IA sets if the users will keep using the application you designed or not. It is important to come up with a fully-tested and workin IA, before starting to code. Afterwards making the changes in the IA and re-coding the application can be very expensive.

One of the most important goals on an IA project is to institute a consistent user experience for two key elements: the visible navigation user interface, and the underlying — invisible — structure (where things are found on the intranet). (Nielsen, 2007)

The beginning of school was a bit intense - in September when we had regular school-classes basicly every day, but since October we have been oriented on team-work and personal research. Besides the traditional classes, I also participated in 2 EMIM’s e-courses, which have been my first e-course experiences. So, I’ll give a short overview of the courses I had in fall 2007.

Introduction and theoretical foundations to new media

An interesting course lectured by Prof. Mauri Kaipainen. The course was basicly about introducing the concept of new media. We had the classes in our fancy media-lab, where we discussed on topics concerning digital media, the learning environments, knowledge-sharing services, web 2.0, digital art and virtual communities. Loads of new information.

Official description of this course.

Academic writing and hypertext

Another course by Mauri Kaipainen. As there are a lot of essays and academic papers to write, we were introduced the technics to use. We studied the academic text, learned about referencing and did some cool exercises.

Official description of this course.

Game interactions

An unbelievably fun course about gaming history, research and development. The course was lectured by 2 guys from Sweden: Ulf Hagen and Jon Manker. It was also quite practical, because at the end we had to come up with a game-conception and a design paper. A post, I’ve written in September about this course.

Official description of this course.

Open source management

Also, a enjoyable course that was about working with open source software development tools like TRAC and SubVersion. In the beginning we were divided into 2 teams and we had to start developing a campaign for an open-source game called Battle for Wesnoth. Actually, today we had the final lecture and we had to present our campaigns. The campaigns, which at first seemed too difficult to develop, came out pretty funny, I guess. The course was lectured by Kaido Kikkas.

Official description of this course.

Interactive TV

MPEG2, HD, IPTV, HDTV were only some of the keywords introduced us by Artur Lugmayr. We studied about the development of TV and the TV’s digital future. Although, this course a bit too technical, we had a cool teamwork project, which was about combining classical TV and the fabolous Second Life virtual world. Some day we’ll make it come true.

Official description of this course.

Digital culture

Digital culture was one of the e-courses I had. It was basicly about chatting in an online-forum with co-students around Europe. Every week we had a new topic - we discussed over web 2.0, emerging technologies, e-commerce, social issues etc. There was also an interesting teamwork, which was about creating a wiki about the digital revolution in the South-Asian countries. The course was lectured by Melissa Lee Price from Staffordshire University, UK.

Official description of this course.

Project management

My second EMIM e-course, that made us to practice some project management methods. Besides, different project management tools were introduced by our lecturer Carina Roels from ITIN, France. The main scope of this course was to organise the promotion to the EMIM module and that was done in small international teams. Ofcourse, all the communication was online, that made the organisational work a bit complicated.

Official description of this course.

Spring 2008?

Spring 2008 will serve the following courses:

• Interface and interaction design
• Digital interactive audio
• Research methods
• History and visions of interactive media

Also, there are some interesting e-courses to take:

• New Interactive Environments
• Creativity and Innovation
• Visual Communication
• E-learning

New friends, new knowledge. I’m happy with that:)

Besides open source software movement there are other projects around that carry the “free culture” spirit. There is such a organisation called FreeCulture.org, that connects students and young people who have the mission to introduce the free culture movement to their peers. The organisation was founded already at 2004 and since then has been connected with several projects (althougn mainly only in North-America).

The manifesto of the freeculture.org states:

The mission of the Free Culture movement is to build a bottom-up, participatory structure to society and culture, rather than a top-down, closed, proprietary structure.

We believe that culture should be a two-way affair, about participation, not merely consumption.

One project they initiated “Pledge to Boycott DRM” was about to pledge to boycott CDs with DRM (Digital Rights Management). DRM is basicly about limiting the usage of digital media. The CDs with DRM could only be played on certain players, so that people couldn’t make illeagal copies and easily share the music with the rest of the world. For example the big companies came up with CDs that could not be played with Windows Media Player. Since 2002 many law-cases have been handled about the DRM policies and due to that companies started to give up using DRM. EMI was the last one to say in January 2007, that they have stopped publishing audio CDs with DRM.

Anyway, about the project now. Elizabeth Stark and Fred Benenson from FreeCulture.org stated: “I will pledge to never purchase a CD containing any form of Digital Rights Management (DRM), but only if 500 people around the world will do the same.” The campaign was highly succesful and alltogether 4562 people signed up (it’s 9 times the people they expected to sign up). They could only achieve these because of the community - students and young people wanted o express their feelings against the DRM policy and were ready to sign their name on the public website. This all happened when the topic was still hot and I’m pretty sure this project somehow helped to make the next step towards the DRM-free world.

It’s interesting that Steve Jobs, CEO of Apple, has also pointed out his thoughts about DRM and music. Apple and Steve Jobs are in opinion that music should be DRM-free and that’s why the popular iPods an iTunes support the music that is encoded in “open” licensable formats such as MP3 and AAC.

The simplest answer is because DRMs haven’t worked, and may never work, to halt music piracy.

As free software may be freely redistributed, free software generally is available at very little cost. Free software business models are usually based on adding value such as support, training, customization, integration, or certification. It’s not easy to find the right solution for marketing a open-source product, but still a lot of companies (especially the ones distributing Linux) have become very successful.

Examples

Let’s talk about Red Hat succes-story. With projected revenues of about $300 million last year, the 13-year-old company relies on a subscription model. An annual fee per server buys updates, upgrades, certifications, unlimited incident support throughout the year.

One strong example would be also JBoss, which is a division of Red Hat. JBoss has managed to sell conferences, support, certification, even a reference manual. Each of these profit centers provides a strong revenue stream. Providing a strong application server platform, along with a company of services and development concepts to support, JBoss has certainly been able to use the community to help develop their vision.

MySQL employs a dual licensing model. It distributes the database software for free if people agree to distribute any modifications under the GPL, which is the basic license for a lot of (but not all) open source software. The other part of the dual licensing agreement covers the MySQL Enterprise edition, which comes with services and support and doesn’t require redistribution.

A similar example would be Eclipse which is a development platform comprised of extensible frameworks, tools and runtimes for building, deploying and managing software across the lifecycle. If you want, you can use it for free, but people at Genuitec saw an opportunity for a cool service, MyEclipse, a subscription based toolbox for enterprise Eclipse development.

A failure?

It’s hard to find real failures in this field, but after reading this article it seems like atleast one open source operating system has chosen wrong strategy. We’re talking about Linspire, which is said to be the easiest desktop Linux. At first we could argue about the quality of this software, because there is nothing much special in Linspire: Debian has the history and dpkg. Fedora has the legacy of Red Hat. SuSE has the huge community and Novell’s backing. Ubuntu has the six month cycle and the wonderful community. And Linspire has… CNR (the Linspire package manager).

Besides that Linspire has made a not-so-good deal with Microsoft which is about adding Windows Media, Live Messenger, TrueType font and MS Office support to Linspire. The idea seems to be good, but Linspire doesn’t have the guarantee for future support from Microsoft. If Microsoft comes out with new versions of the applications mentioned, Linspire should buy a new support-package and what is the worst - Microsoft can stop offering protection whenever they want. Could they survive without the support for these mainstream MS applications?

Conclusion

In general it seems to be quite easy to come up with a company selling CD’s with the recent version of GIMP, but in real-life finding customers doesn’t seem to be the easiest task anymore. As we can see, there are companies who know the secret of making money with open-source products. Customers are willing to pay for the support they get from the software developers and distributers. Also a model providing open-source products pre-installed on servers and other gadgets is a popular one.

Some open source purists will argue that the vision behind the open source project should be the project itself and the community that will benefit from it. But these days, it’s common that companies work with the community to both give back to the company that initially invested in the project.

Since free software is often the easiest solution for companies looking for new markets and fast product-development (as it’s free), there are numerour cases where companies tend to misunderstand or overlook the licenses attached to open-source software (usually GPL).

Case study “Verizon”

Verizon, a telecommunication gigant has one of the latest GPL-related lawsuit to handle. The Software Freedom Law Center has sued the company on behalf of the developers of BusyBox, a set of Unix utilities typically used in embedded systems. According to the license the source code should have been added to the box, but for some reasons the company has failed to do it. At first the developers informed the company about the problem but as the company did not respond, they had to sue Verizon. The case is still open.

Actually The Software Freedom Law Center has filed three other lawsuits on behalf of the BusyBox developers (Erik Andersen and Rob Landley) claiming improper use of this device. One was settled, while the other two remain pending.

Case study “SCO”

On March 6th 2003 The SCO Group (a software company focused on UNIX systems) sued IBM for contributing with no authorizaton SCO’s intellectual property to the codebase of the open source, Unix-like Linux operating system. And that was a $5 billion lawsuit. SCO wanted revoke IBM’s license to ship its version of Unix and even sent a warning to the biggest companies who might be using Linux, that the operating system might not be reliable. The question was about owning the intellectual property rights: SCO was in opinion that after buying UNIX operating system in 1995 from Novell also received the copyrights and stated that Linux contains features from the UNIX that they had bought and further-developed.

This lawsuit caused outrage in the free software and open source community. They had arguments such as SCO actually doesn’t own the code and they’re not the owners of the UNIX operating system. Besides that it was mentioned the Linux operating system was written form cratch by hundreds of collaborators with a revision history. They also pointed out that Linux might have the same features as the UNIX developed by SCO has, but it doesn’t mean that the code has been copied from SCO UNIX - it could have been done from other open-source operating systems.

The lawsuit ended on August 10th 2007, when the court announced that Novell (and not the SCO Group) is the rightful owner of the copyrights covering the Unix operating system.

Considerable is the fact that after losing the lawsuit, SCO lost 70% value of its share on the market.

Abstract

In this short article Lauri Laineste takes a closer look at the ‘Open Source’ and ‘Free Software’ definitions. The point of this article is to make clear what are the differences between Open Source,- and Free Software schools and why there is a need for two different licenses. Laineste brings out the conditions that a software has to fill in order to gain the Open Source or the Free Software license.

Introduction

During the golden 60’s, when the first commercial computers started to spread, software on the machines was free (libre). It came with source code and was easily shared. The business at these times was the hardware. But during the 70’s computers became less expensive and more accessible - non-technical office workers and home users had a need for computers. The software companies started to see an oppurtunity in making money with software. Companies started to sell only the compiled binaries.

The situation started to change in the mid 80’s, when Richard Stallman saw an danger in propertiary software: users could buy a copy of a program but couldn’t change or distribute it. Without source code the software had no value. One thing lead to another and the organisations fighting for libre software were born.

Research question

What is the main difference between Open Source and Free Software schools?

Methods

Literature analysis is used in creating this article.

Open Source

OSI stands for Open Source Initiative and is a organisation that promotes open source software. According to Wikipedia the organisation was founded in February 1998 by Bruce Perens and Eric S. Raymond when Netscape Communications Corporation, published the source code for its flagship Netscape Communicator product as free software, due to lowering profit margins and competition with Microsoft’s Internet Explorer software.

Free Software

FSF stans for Free Software Foundation and is a organisation to promote free software movement. According to Wikipedia the organisation was founded on October 4, 1985 by Richard Stallman to support the GNU Project.

FSF vs OSI

Both of the schools have more or less similar aims, but differ in their philosophy and values. Open source is a development methodology; free software is a social movement. People intend to mix these 2 principles.

The definition of free software (via fsf.com): Free software is a matter of the users’ freedom to run, copy, distribute, study, change and improve the software. More precisely, it refers to four kinds of freedom, for the users of the software:

• The freedom to run the program, for any purpose (freedom 0).
• The freedom to study how the program works, and adapt it to your needs (freedom 1). Access to the source code is a precondition for this.
• The freedom to redistribute copies so you can help your neighbor (freedom 2).
• The freedom to improve the program, and release your improvements to the public, so that the whole community benefits (freedom 3). Access to the source code is a precondition for this.

A program is free software if users have all of these freedoms.

The definition of open source (via opensource.com): Under the Open Source Definition, licenses must meet 10 conditions in order to be considered open source licenses:

1. Free Redistribution: the software can be freely given away or sold.
2. Source Code: the source code must either be included or freely obtainable.
3. Derived Works: redistribution of modifications must be allowed.
4. Integrity of The Author’s Source Code: licenses may require that modifications are redistributed only as patches.
5. No Discrimination Against Persons or Groups: no one can be locked out.
6. No Discrimination Against Fields of Endeavor: commercial users cannot be excluded.
7. Distribution of License: The rights attached to the program must apply to all to whom the program is redistributed without the need for execution of an additional license by those parties.
8. License Must Not Be Specific to a Product: the program cannot be licensed only as part of a larger distribution.
9. License Must Not Restrict Other Software: the license cannot insist that any other software it is distributed with must also be open source.
10. License Must Be Technology-Neutral: no click-wrap licenses or other medium-specific ways of accepting the license must be required.

Conclusion

It seems like for the Open Source, the question whether a software should be open source, has a practical meaning (the availabilty to modify the code); for the Free Software, it seems to be like a principal, that the users have the right for free software.

So, what’s the sitation today? Actually, I even can’t remember the last time I turned the TV on in order to watch a movie or another episode of Simpsons. Since I moved to Tallinn 5 years ago to start my studies at university, I haven’t had a TV at all. To be honest, I never had a need for it. Since everybody and everything is connected to the net, the classical TV is not so tremendously interesting anymore. Classical TV is static, internet isn’t. So, in order to stay popular and gain new watchers, the old and good TV has to change fundamentally.

Internet killed the television star

In general, TV needs to get interactive. Interactivity sells and it’s so old-fashioned to watch “Friends” only once a week on specific time. It would be more attractive to see the movies and serials on the times, that are most suitable for you. And if you feel like, the TV box should enable you to show all the “Friends” episodes in a row. That would be fun! This kind of features are not supperted by the classical TV, but engineers have been busy developing a lot of cool applications that bring TV to the next level.

A lot of Internet-based TV applications have shown up lately: the popular Joost, Babelgum and Zattoo etc (via Read/WriteWeb). Joost was one of the first successful pioneers to show up in the internet-based TV world. I’ve been Joost’s beta tester since January and have seen the amazing development of this application. At first, it had only some sample programs and now there’s a great variety of programs and 250 different channels all together. Joost is based on P2P technologies (the more user it has, the stronger the connection is) and is a typical video-on-demand example. You decide when you’re in a mood for another Happy Tree Friends cartoon or a political debate. That’s the most important feature IPTV application can deliver.

Besides the video-on-demant feature, Joost has a lot of useful widgets. Personalizing is the keyword at the moment and Joost has all the tools that are neccessary to configure the application in the way you want. The widgets let the users to chat with friends via Gmail Talk or Meebo. The Meebo add-on was introduced a week ago and gives a totally new perspective for the Joost’s functionality. In addition, all the users who are watching the same contect, can chat in a public chatroom and share their thougts about the show. The chatroom is another cool social-feature that makes Joost much more fun to use. Rating the programs and reading the news are also some possible actions you could do while watching the channels on Joost. I wonder when they add the social networking side to Joost - so every members could create a profile that contains the information of the programs they have seen, which are the highest rated shows, what are their friends watching and what they are waiting to see.

Babelgum is similar to Joost, but doesn’t contain so many channels as Joost has. Babelgum lets the users to great personal playlists and in general is a straight-competitor to Joost. Zattoo, which has been mentioned before, has only Swiss-content at the moment and differs from Joost and Babelgum in the way, that it’s streaming the live-shows. So, it’s not so flexible, but a great application to keep your eye on the content that’s being showed at the moment.

Grassroots journalism in TV

Publishing news has been the main feature the TV has always delievered. There are channels which have concentrated only on the news and the others publish news as short and informative programs. The changing TV and developing technologies have given new oppurtunities to publish news and give a new perspective to grassroots journalism - the journalism that can be created by everyone (and not only by professional journalists).

Al Gore founded an innovative TV program - Current TV, which lets users to contribute in creating the news. Interesting is the fact that the channel is preparing to make the break-through in the web. The web is more flexible in order to make Current TV more attractive and interactive. In the web the users could submit videos and video-comments arranged by their web-cams and rate the news so other users could see only the most relevant materials. It will have basicly the same principle as Digg has, but it will be in TV. Cool! MacManus introduces one of its feature called Viewpoints - all the users can submit 1-minute-long video-comments on certain topics and then other users can rate the comments or post their own 1 minute-long video-comments. The most relative video-comments are shown on Current TV channel. Indeed, a new and frash way to browse news.

Mobile TV

Mobile media will be the next big hype after the social revolution in the web. As I mentioned in my last article (Mobile Revolution), mobile services have started to develop fast and everyone wants to be mobile. Partly it’s because the new technologies enable to create quite complex services and nearly half of the world’s population is connected via mobile devices. So, what about watching your favourite movie from a mobile? Ofcourse it’s not the same as doing it in the cinema while eating pop-corn, but in some cases the mobile TV will certainly rock the market. For example, watching news and some short programmes would be quite well followed from mobile devices. Still, Mobile TV is making it’s first steps and not reachable for everyone.

Mobile TV could be successful if the companies could agree on the revenue model and common standards. At the moment you pay for mobile TV according to the megabytes you download, but it would be much more reasonable to pay for certain shows and programmes. It would make the pricing also more clear to customers.

Mobile TV requires much more resources to build a stable network as building a traditional TV network. One possibility would be to use DVB-H (Digital Video Broadcasting - Handheld). It enables to build networks similar to classical TV - there will be one neutral operator that operates the mobile TV network. The network will be used by (mobile) companies who could publish their channels. In total, there can be up to 40 different channels in one network - some of them can be paid and some will be opened for everyone (like the national channels in TV).

Conclusion

TV is a huge business and everyone wants to take it’s share. Nowadays it’s not only the business of broadcasters, but also the software and mobile companies are keeping their hands busy creating new and interesting TV-applications.

In order to stay popular, TV has to change it’s structure and gain the features the all-powerful internet has. Nobody’s interested in the static TV anymore - while watching a movie that was directed by Steven Spielberg, I’d like to get all the information about the movie and the producer, other movies directed by him, ratings, reviews and user-comments of the movie. It all should be online and done in one interface.

It’s also the question of globalization - people are not depending on the desktop PC’s anymore, since the global lifestyle prefers laptops and now even more smaller and lighter mobile gadgets. Mobile services are one of the biggest trends in the future web-world (MacManus, 2007).

Jaokar (2006, 1-15) explains the human need for Mobile 2.0 services. He’s doing it very creativly using the Maslow’s hierarchy of needs. The theory sais that there are some things whitout we couldn’t live (we need food and sleep) and after we have achieved them, we start to look for something more (we want to feel secure and to be loved) etc. Now, the same theory has been set to the mobile services - after achieving the basic needs (calling the ambulance in case of accident), people want more out of the mobiles (i.e order ringtones, send MMS’s etc) and the highest element in the pyramid is creating content and using complex services with mobile devices. Actually we could live without them, but there still is quite clear need for these kind of services.

Mobile technologies have given a strong input for the citizen journalism development. Newsvine, one of the most popular citizen journalism sites, was recently acquired by MSNBC. It shows, that the leading news-agencies see the potential in citizen journalism and have started to give more attention on this issue. But not only the agencies, also the mobile companies want to take their share. Interesting is the fact, that Nokia has developed in co-operation with Reuters a The Mobile Journalsim toolkit, that consists of a multimedia phone equipped with a Bluetooth keyboard and other fancy gadgets. It shows that journalism is getting more-and-more mobile and gives an oppurtunity basicly for everyone to take part in the journalism process. Daily newspapers have sections, where their readers can submit photos and videos taken on the streets and from places where the reporters already have missed the “big fire” or the accident. It has all the characteristics of Web 2.0, which is the keyword for user-created-content.

Intersection of mobile and Web 2.0

Kharif (2006) points out that since mobiles are ruleing the market, popular social networking sites like MySpace and Facebook have opened mobile services. The PC isn’t necessary anymore to keep the eye on your friends’ activities in Facebook or MySpace. It’s easy to take a snapshot with your handy and instantly upload it to the web - a cool way to share your travellings with your friends and family at home. Interesting is also the fact, that some mobile companies have contracts with social networking sites, so the phones have pre-installed applications to make communicating with the site and uploading new photos even more easier.

Actually the same thing is going on with blogging - the PC is boring and clumsy. Use mobile devices to post about your trip to south-Spain and with a integrated GPS it’s possible make it really interesting to follow. Locative services will rock the mobile market.

Locative services

The advantage of the mobile devices is the fact, that you always have them in your pocket and ready to use. Jensen (2007) is in opinion that, the next big thing after Web 2.0 will be locative services. I totally share this idea, because all the information in the web would have much more value if it has been tagged with it’s location. It would be cool to save the keywords “champions league final live” (if you’re interested in watching tonights game) and while walking around in the city, your mobiles gives you a hint that the pub cross the road is showing this game live. The information gets relevant in these specific locations.

It’s also with the million Flickr images. They would be much more valuable, if they were seen at some specific locations (but not at your desktop). Imagine yourself being a tourist in India and you would receive a bunch of photos of Taj Mahal being close to the building. It would give a good overview of the building - some pictures are zoomed in, taken in different light conditions etc.

In Tokyo, a new mobile service is being tested at the moment. Michael Fitzpatrick (2007) mentions that the RFID tags are used to describe the streets, shops, underground, etc in Tokyo. There’s also a practical reason for that - the city is huge and even some streets don’t have names, so for tourists getting lost in Tokyo would be no problem. The new system indicates if the supermarket has a sushi-restaurant or in the underground the mobile would show you the photo how the stop looks from the street - so you could easily recognise your stop (in case you feel a bit uncomfortable in japanese).

Mobile services go too far?

Yuki Noguchi (2006) introduces an application Dodgeball, which is a mobile social software. The point of this application would be tracing your friends with a mobile device - it will give you an overview where your friends have been. Actually it has quite a lot of features, even the popular dating service. While walking around in the city, you could specify that you would like to meet a 22-year-old brunette who likes classical music. And wow, you’re mobile will let you know, if there are any of these girls close to you. Dating 2.0? Besides it’s possible to receive messages if some of your friends is in a nearby cafe.

Actually these kind of services have quite a serious privacy issues to face, but nevertheless, it seems like people still want to ‘be on the map’. Interesting is the fact, that this service is owned by Google. It won’t take a lot of time, before Google will know everything about us. But yeah, fortunatelly the phones still have the magical shut-down button.

Conclusion

Mobile services and especially locative services will receive more and more attention. It seems like all the big web-companies are finding ways to reach the mobile market. At one point of view it will boost the technological development on mobile devices, which is definetely good. Besides that, mobile manufacturers are opening SDK’s, so software developers could write cool widgets for mobile devices. Recenlty Apple introdeced the SDK for iPhone. That’s a great oppurtunity to develop even more complex mobile services. Entrepreneurs from the mobile field intend to call these services also as Mobile 2.0 (most probably because of the Web 2.0 hype), but one thing is sure - the desktops are being conquered by all-powerful mobile gadgets.
