| Research Abstract |
We have developed user interfaces for a mobile device equipped with a video projector. System development for stabilized projection by which the projected contents are fixed on a planar screen without being affected by the motion of the mobile device was carried out and user interfaces utilizing the motion of the mobile device while the projected contents are fixed on the screen. The results include namely a projector firmware to apply arbitrary homography transformations to the projected contents at 1300 frames/s, a pose and position estimation algorithm for a mobile projector-camera system exploiting geometric constraints between the system and the planar screen, and operation interfaces utilizing the pose and dynamic motion of a mobile device.
