CN-108688563-B - Use of virtual mirror for automobile

Abstract

The present invention relates to the use of virtual mirrors for automobiles. A system, method, and computer-readable medium may include techniques to achieve optimal use of virtual mirrors for automobiles. The gaze detector monitors the eyes of the driver to determine if the driver is looking in the direction of the virtual mirror. If the driver is not looking in the direction of the virtual mirror, then all virtual mirrors are placed in a low operation mode. If the driver is looking in the direction of one of the virtual mirrors, the virtual mirror being viewed is placed in a high operation mode and all other virtual mirrors are placed in a low operation mode.
