Video Switching System Using Non-Contact Interface by Image Processing
Kazuo Hemmi · 2017
We describe a method to detect human movement using a single camera and construct a non-contact human interface in this paper. In this system, a virtual switch is set in the air, and when the user touches the virtual switch, built-in five videos can be sequentially switched. In order to examine the operation accuracy of the system, a total of 460 evaluation experiments were conducted. The evaluation experiments were conducted on two cases, i.e., the case where the operation was performed without passing through the glass and the case where the operation was performed through the glass. As a result, the success rate in the case of not passing the glass was 95.8%, the success rate in the case of passing the glass was 96.0%, both were a very high recognition success rate. From these result, we can say that this system is sufficiently practical as a human computer interface. Furthermore, it was confirmed that this system can be operated through the glass. This means that this system can be operated from the outside even if it is installed in the show window. When we install the proposed system to a computer with built-in camera, we can easily construct an inexpensive interactive digital signage without any external device.
