The AAL project SI-Screen focuses on providing an innovative user interface for elderly people enhancing their access to awareness streams of Social Networking Services by using tablet computers. As part of our attempt to investigate the acceptance of the newly developed user interface, we assessed the display size and touch input accuracy of multi-touch tablet computers in a multi-directional tapping task as proposed by the ISO 9241-9 standard. For this assessment, we realized the multi-directional tapping task as custom application for Android tablet computers and smartphones. (Source: Burkhard et al. 2012)
