- Design implications for mobile user interfaces of Internet services
Doctoral dissertation (article-based)(2009) Vartiainen, ElinaInternet services are becoming essential in people's daily lives. In addition to accessing them on a PC, Internet services offer functionality and content that are also relevant for mobile use. At the same time, mobile devices of today are technologically sophisticated enabling online access anytime, anywhere. The remaining challenge is to utilize the capabilities of a mobile device in a way that offers people a positive user experience when they are using Internet services on the go. This Thesis belongs to the area of Human-Computer Interaction focusing on the use of Internet services on a mobile device. It considers the limitations of a mobile device in terms of user interface design and its goal is to define design implications that assist in designing mobile user interfaces for Internet services. The design implications mainly aim to give guidance on how to design a mobile Web browser, but they are completed with research findings on designing a mobile client application for an Internet service. The research was implemented through user needs studies, user interface design, and user evaluations. The research studies focused on two approaches that support the use of Internet services on mobile devices: the Minimap Web browser and the Image Exchange mobile client application presented these two approaches. The resulting design implications suggest that the following aspects should be considered when designing mobile user interfaces for Internet services: content optimization, utilization of desktop and mobile usage patterns, full exploitation of device capabilities, compensation for device resources, and content updating. The possible differences in characteristics of a mobile Web browser and a mobile client application are also examined. Finally, this Thesis discusses the latest developments that enable alternative ways to support Internet services on mobile devices in the future. - Implications of the Business Backgrounds and Technologies of the DVB-MHP and OCAP Interactive Television Standards
