Abstract
With modern mobile devices information like emails or calendar entries are easily accessible. During a phone call when not using a headset these capabilities are lost. Emerging projector phones could overcome this bottleneck with their capability to project a separated interface onto nearly any kind of surface. But still the problem exists of how to control this projection. In this paper we present and evaluate a one-handed interaction paradigm for projector phones that allows accessing the full phone capabilities during a phone call, such as apps and personal information management tools. This interaction paradigm is robust and easy to implement. In a user study we evaluate one possible implementation of the proposed paradigm.
