Abstract
The tutorial presents a collection of patterns addressing issues regarding designing user interfaces on mobile devices that we have developed in a two-year research project and currently develop further in a two and a half year research project. The patterns address typical challenges and opportunities when designing user interfaces that are to run on PDAs and SmartPhones – both challenges connected to characteristics of the equipment and connected to tasks to which designing suitable user interfaces is challenging. The patterns in the collection are structured in three main groups: 1. Utilizing screen space2. Interaction mechanisms3. Design at large. The suggested solutions are based on existing design practice, and the description includes examples of good solution and pros and cons of different approaches. The participants at the tutorial will learn about design challenges and opportunities that are specific and important when designing user interfaces on mobile devices. They will obtain general knowledge about approaches for overcoming the challenges and exploiting the opportunities, in addition to specific knowledge about solving the most important problems. Participation in the tutorial will be beneficial for the IASTED-HCI audience because it both gives a structured overview of the challenges and opportunities connected to user interface design on mobile devices, and gives practical solutions to the most important challenges, including adaptive and context sensitive user interfaces and multimodal interaction. Tutorial documentation will include a comprehensive research report documenting the patterns collection, in addition to important choices regarding platforms, user interface style and deployment strategies, overview of main differences between mobile and stationary user interfaces, and important issues from platform style guides. Furthermore, the tutorial documentation includes an extensive bibliography.
