In the doctoral colloquium at Ubicomp 2008 we saw an interesting mix of topics including work on context-awareness, interaction in smart space, home infrastructures and urban environments. Overall there is again the observation that in ubicomp topics are very broad (at least in the beginning) and that it is not easy to narrow it down.

PS: Just one remark on the term “framework” (a favorite word to use in dissertation and paper titles) – it is not a clear term and expectations are very different, hence it make sense to think twice before using it 😉
The conference on mobile human computer interaction (MobileHCI 2008) started today in Amsterdam with the tutorial and workshop day.
I am chairing the tutorials and we tried a new approach for the tutorial, having 6 sessions/chapters that all together make up an introduction to mobile HCI. After 10 years of mobile HCI it seems important to help new members of the community to quickly learn about the field. The presentations were given by experts in the field that had 1 hour each for their topics. We had unexpected high attendence (the room with 100 seats was nearly always full). Have a look at the slides:
Text input for mobile devices by Scott MacKenzie
Scott gave an overview of different input means (e.g. key-based, stylus, predictive, virtual keyboard), parameters relevant for designing and assessing mobile text input (e.g., writing speed, cognitive load) and issues related to the context of use (e.g., walking/standing).
Mobile GUIs and Mobile Visualization by Patrick Baudisch
Patrick introduced input and output options for mobile devices. He will talk about the design process, prototyping and assessment of user interfaces, trade-offs related to the design of mobile GUIs and different possible interaction styles.
Understanding Mobile User Experience by Mirjana Spasojevic
Mirjana discussed different means for studying mobile user needs and evaluating the user experience. This includes explorative studies and formal evaluations (in the lab vs. in the field), including longitudinal pilot deployments. The lecture discusses traditional HCI methods of user research and how they need to be adapted for different mobile contexts and products.
Context-Aware Communication and Interaction by Albrecht Schmidt
Albrecht gave an overview of work in context-awareness and activity recognition that is related to mobile HCI. He discussed how sharing of context in communication applications can improve the user experience. The lecture explained how perception and sensing can be used to acquire context and activity information and show examples how such information can be exploited.
Haptics, audio output and sensor input in mobile HCI by Stephen Brewster
Stephen discussed the design space for haptics, audio output as well as sensor and gesture input in mobile HCI. Furthermore he assessed resulting interaction methods and implications for the interactive experience.
Camera-based interaction and interaction with public displays by Michael Rohs
Michael introduced camera based interaction with mobile devices; this included a assessment of optical markers, 2D-barcodes and optical flow as well as techniques related to augmented reality. In this context he addressed interaction with public displays, too.
