Generating spatial attention cues via illusory motion

For many applications in augmented reality (AR), the user has a much more enjoyable experience if the AR system is able to properly guide the user’s attention. In this extended abstract, we explain how to create patterns of light that when projected onto an object are perceived as if the object itself is moving.

This can be used as a spatial attention cue. We accomplish this with a calibrated projectorcamera setup to synthesize an image from the projector’s point of view. This image is filtered to create local phase changes that are then projected back onto the object and perceived as motion. Our method will be shown as a live demonstration at the CV4AR/VR workshop at CVPR 2019
