Especially the interaction with small targets on mobile devices has gained quite some interest in the last years. This lead to new interaction techniques such as Shift [21] of Escape [23] being based on fine granular zooming techniques or gestures. We assume that, based on the results presented in this paper, those techniques can’t effectively be used when walking as very accurate finger movements or gestures have to be performed. Our future work will focus therefore on the development of adaptive user interfaces allowing the user to accurately select small targets on mobile phone screens. At this we will consider especially the provision of semi-transparent information on top of the previously selected information, which helps the user to perform the correct selections without losing or changing the context.
