In peephole interaction a window to a virtual workspace is moved in space to reveal additional content. It is a promising interaction technique for mobile projector phones to display large workspaces which contain more information than can be appropriately displayed on a small smartphone screen. In this paper we describe a projector phone prototype that implements peephole pointing without instrumenting the environment or using any additional hardware besides a smartphone and a handheld projector. This device allows for the first time to perform peephole interaction in the wild. Moreover, we demonstrate some applications we have built to exploit and investigate the full potential of peephole interaction with projector phones.
