Human-computer interaction system combining personnel detection and privacy-protected touch display functions

Abstract

A human-computer interaction system combining personnel detection and privacy touch display functions includes a controller, an object detection module that detects objects in the space in front of it and the distance and direction of the objects relative to the object detection module to obtain object sensing data, a privacy touch display, and a camera device. The controller determines whether to switch the privacy touch display to privacy mode and whether to operate the camera device to record video based on the object sensing data. The controller can execute a graphical interface application software. The controller determines the content displayed by the graphical interface application software on the privacy touch display based on the object sensing data provided by the object detection module, while preventing the information displayed on the privacy touch display when operating the system from being spied on by others.
