Our world is full of cameras, whether they are installed in the environment or integrated into mobile devices such as mobile phones or head-mounted displays. Displaying external camera views in our egocentric view with a picture-in-picture approach allows us to understand their view; however, it would not allow us to correlate their viewpoint with our perceived reality. We introduce Projective Bisector Mirrors for visualizing a camera view comprehensibly in the egocentric view of an observer with the metaphor of a virtual mirror. Our concept projects the image of a capturing camera onto the bisecting plane between the capture and the observer camera. We present extensive mathematical descriptions of this novel paradigm for multi-view visualization, discuss the effects of tracking errors and provide concrete implementation for multiple exemplary use-cases.
