Interaktionsdesign för kommersiella webbtjänster
The company Microshop is interested in implementing new features in their product-website, and would like to examine the possibility and usefulness of introducing such functionality. When designing interaction for commercial websites, it is important to make the menus easy to use, and refrain from using deep hierarchies in order to avoid causing unnecessary burden for the users. There is an interest among users for adaptive functionality, but this requires great amounts of trust in the website from the user. Something which can be created by refraining from using implicit information, and provide detailed explanations throughout the website. A usability test was conducted in order to complement the data gathered from the theoretical study, the interviews and the expert evaluations. This test evaluated the interface design and the necessity of the proposed functionality. The test was carried out under controlled conditions, and was conducted as a series of user observations of the trial participants. Results showed that there is a need for adaptive functionality, but that the existing interface requires an update before additional functionality is introduced. Proposals on how this could be solved are presented as a number of design proposals which would address the problems, and propose a design for the new features. The usability test proved extremely capable of identifying errors that occurred when the participants corrected their previous actions. In addition, the users trust in the interface, and their previous computer experience contributed to interesting results.
