Location awareness (LA) is an hot topic in this period, due to its application on the development of location based services (LBS) that could offer a new gamma of opportunities for mobile users. This talk will present various attempt to incorporate LA on mobile services and the analises of some unsatisfactory obtained results. In fact, adding this features is not always positive for the users’ interaction on the device. Some results shows that automatic positioning may decrease collaborative performances. Others, shows that messaging based on location does not solve the ambiguities of context definition. The summary of the presentation will focus on research techniques used to enquiry mobile interaction design and usability of the interfaces.
Here are the slides I am presenting tomorrow at the HCI group at EPFL.
