This report describes the development of an application in collaboration with Designingenjörerna AB. The company has worked for a long time with a community platform and they required an application where users can create their own unique profile representations, called Avatar Creator. An Avatar Creator is computer based application, which makes it possible to create a virtual character. The problem area behind this is that, large websites require a lot of administrative work when people upload profile pictures on different community pages. They can contain abusive material or pictures of other people rather than those who created the profile.The questions in this report are, how can an Avatar Creator help user to get a unique profile of himself? What are the advantages and disadvantages of an Avatar Creator? How to create a user-friendly application?To understand how an Avatar Creator works and get ideas to create an application, exiting Avatar Creators were reviewed on the Web.Collaborative work with Designingenjörerna AB was done to pin down the requirements for the Avatar creator application.

The aim of our bachelor thesis was to study how the personnel incharge of the mobile websites at two University Libraries and thestudents at those Universities viewed the mobile websites, and iftheir views in any way differed.Our research questions were:Why have the examined Libraries chosen to offer mobilewebsites?How do the students at the examined Universities experience anduse respective mobile website?Are there differences between the staff?s intentions with themobile websites and how they are used and experienced by thestudents, and how could they be explained?Semistructured interviews were conducted with six staff membersresponsible for the mobile websites and eleven students that hadexperience in using these. The theoretical framework for thisthesis consists of Klasson?s three models for University Librarianspersonas, and the parts of Rogers theory about diffusion ofinnovations that concerns the attributes of innovations and thecommunication channels.The result of the study indicates that there are some differencesabout how the students use and experience the mobile websitesand the staffs intentions for them. The students required contentwhich the staff had discarded.

This graduation paper treats e-mobbing via the different communication medias of the mobile phone. The purpose of the research has been to describe student?s experience of e-mobbing via the mobile phone?s different integrated functions as phone calls, sms, mms and e-mail.In this poll investigation asked 100 students of 15-20 years of age.The interviews made have shown that girls are more exposed to e-mobbing, e.g. indirect mobbing. In my research it is possible to see that girls are more exposed than boys to threats of violence via sms, the spreading of rumours and the danger of being called different things.It is also possible to see in the result of the interviews that the mobber wants to experience power, something which is not unusual in all types of mobbing.

The Mobile phone has contributed to massive changes in the way that human beings communicate with each other and is a part of society?s globalization. Opinions differ in the area of user interface where some feel that mobile phones exclude users such as senior citizens or users with an intellectual or a physical disability.Universal Design ??design for all?, is a vision that intends to bring about settings, products and services that suits as many people as possible irrespective of an individual?s needs and prospects. The criteria for ?design for all? are among other things flexibility, user friendliness, comprehensibility and a high tolerance for mistakes.The purpose of this essay was to investigate the mobile phones graphic user-interface from the theory of a universal design.

Researchers today anticipate that in the near future, the majority of the owners of a smartphone will use it as a wallet, i.e. for contactless payment. The technology that enables contactless payment today is ?Near Field Communication? (NFC), which is increasingly embedded in smartphones. Applications like mobile payment between a phone and a terminal use NFC.

The technology used in the development of web-applications is evolving at such rate that it has become more and more important to keep web-applications modern. If an application is based on a technical platform that is not renewed, the platform may over time develop into an obstacle in further development of the application. There may be compatibility issues and some of the code may be unnecessary due to abstraction, and therefore more time consuming to work with. Sometimes the reason may be that an application has been built to run, and is running on an application server that is no longer being maintained. The system can be large and modernization can cost a lot.

With the new generation of smartphones the boundaries for what is a mobile phone and whatis a computer becomes more subtle. 2009 the shipment of smartphones with touchscreen morethan double the 2008 figure and the total amount of smartphones is now over 10 % of the totalworldwide shipments of mobile phones. There?s still one problem to solve and that is the lackof web content specifically adapted for smartphones.The purpose of this paper is to identify and analyze from a user and usability perspective howto make a successful migration and design of a user interface for an existing web basedsystem so that it also fit smartphones.The paper starts with a theoretical reference material containing examples of differentapproaches for design and migration of an interface.A case study is performed and prototypes are designed with support from guidelines andrecommendations in the theory part.The conclusion stipulates that in the present situation there are no shortcuts when it comes tomigration of an existing web based system for the mobile web. The recommendation is aspecific interface for each different unit that are going to interact with the system.Research that analyzes differences between all mobile web browsers would be of greatinterest, a research that hopefully leads to guidelines for what level of mobile web standardthey should at least support.
