Description
Summary:The purpose of this examination is to study how to create a user-friendly interface to a new non-released website. The research has been done in collaboration with the research institute Acreo and a project named Streamingkollen; a consumer tool that aims to improve the customer’s quality of experience (QoE) of streamed videos by measuring the video streaming quality.     In this study the focus has consequently been placed on the users of the service, in order to optimize their experience of the website and the interface.    In order to achieve a high level of usability, a user centered design process has been used. A user analysis, a heuristic evaluation and user tests on prototypes have been used as methods in the design process and the development of the interface.    The result from the user tests shows that the major reason why the user disliked, felt frustrated or couldn’t manage the service was when the design of the site was not consistent and minimal, when words, phrases and concepts on the site were not familiar and communicated in the same language as the users and when they lacked informative feedback of the operations made on the site.    The user-centered development in the study gave good results; many of the potential usability problems were identified and avoided.
