Kontextmedvetenhet som ett sätt att reducera Information Overload
Designriktlinjer för kontextmedvetna smartphone-applikationer
The main topic of this thesis is to evaluate the impact on the usability of web pages when using responsive web design, a concept for developing web pages whose design adapts to the screen size being used. This is done by creating a responsive prototype based on an existing web site. A number of usability tests are conducted on the two versions of the site in order to compare the time to complete the tests and to observe the behaviour of the test participants. The tests are conducted on desktop as well as on mobile devices with varying screen size.The number of test participants was relatively low, and so the quantitative result is not statistically valid. However, the conclusion is that the most effective combination is to use either of the sites on desktop format. The next best alternative is to use the responsive version on smartphone or tablet, and the least effective alternative is to use the original version on smartphone or tablet.The qualitative result confirms the quantitative result. The difference is biggest between desktop and smartphone formats regarding the effectiveness of completing the test cases. The qualitative evaluation was based on the behaviour and verbal response of the test participants.
