Sociability Issues for Designing Usable Mobile iTV Applications

The adoption of mobile iTV will depend not just fromthe availability of suitable technologies but mainly fromthe limitations related to its use. As for many otherexamples of personal communications technologies,several issues related to the appropriateness of use indifferent social contexts will have an important impactin users’ acceptance of this technology. In this paperwe present three mobile iTV scenarios that highlightsome of the most relevant relationships between tasks,devices, interfaces and the environment that may affectand be affected by sociability. Some findings aboutthese relationships will be described to outline how theymay influence designers to create more usable mobileiTV applications.
