Horizon View Cameraの応用による汎用入力インターフェースの提案

We have proposed Horizon View Camera (HVC), which is a unique system of the object detection by a single camera and has some unique characteristics. HVC is to put a single camera on the ground, and the optical axis of the camera is directed toward the horizon by using a mirror. HVC can obtain two kinds of images. One is the image including only the object on the ground. Therefore, it is possible to detect objects easily. We have shown its effectiveness by measuring distances to objects using the obtained images from HVC with straight motions. Moreover, we proposed HVC-90 that is more effective system than the original HVC for object detection. HVC-90 can detect objects in various motions. In these camera systems, we used characteristics obtained from moving HVC mainly. In this paper, moreover, we develop a unique input interface by using characteristics from standing HVC. We made a potable piano as an example of this interface, and show its effectiveness.
