A User Following Control System for Displays
Bongsu Hahn · Journal of Institute of Control Robotics and Systems · 2017
Traditionally, a display is installed at a fixed position. Hence, to more accurately access visual information, a user must be in front of the display screen, and/or the orientation of the display screen must be manually changed to face the user. To resolve this inconvenience, we propose a user-following control system for displays. This system consists of a camera module, which identifies the user information with the position and number of users, user-tracking control algorithms based on the user information, and a direction-changing mechanism to change the orientation of the display screen and follow the user position. The user-following performance has been verified using several experimental scenarios.
