Opening up new possibilities for UI/VR with ultra-high-speed active cameras.

The non-contact camera, which can acquire a lot of information, is a useful device; however, there is a problem that the spatial resolution decreases when the subject being photographed is far away, which has limited the usability of user interface (UI) systems and virtual reality (VR) systems that use cameras. In response to this, we are advancing the development of UI/VR systems that surpass the constraints of conventional hardware by using an ultra-fast active camera that can rapidly switch gaze directions. By using this camera, not only is wide-range, high-resolution sensing possible, but it also allows for simultaneous acquisition of zoomed images from multiple locations through multi-threaded control. So far, we have developed an aerial multi-touch interface that enables operation using fine finger movements even from a distance, and a VR remote magnification viewing system that allows users wearing HMDs to enlarge and view images from remote locations. Through these technologies, we aim to open up new possibilities for UI and VR.
