It is expected that projector phones (mobile phones with built-in pico projectors) will hit the market by 2010. Such phones provide a completely new way to display information and interaction techniques. The system presented in this paper allows the simulation of these projector phones as the real devices are not yet available. Through this, we demonstrate that it is currently possible to design, develop and evaluate applications for projector phones. The system supports three different modalities in order to compare when which display (phone display, projection) should be used. This prototype system was used for the implementation of two applications in order to test the advantages and disadvantages of projector phones for two common scenarios, picture browsing and map interaction. This demonstration paper describes the hardware used for the simulation of projector phones and the two developed prototypes.
