Abstract
A human-machine interaction method based on visual stimulations. The method can be applied to multiple new technical fields of display, which comprise but are not limited to the fields of virtual reality (VR), augmented reality (AR), mixed reality (MR), holographic projection and glasses-free 3D. The system consists of three parts: a human body biological collection apparatus, a software client for human-machine interaction and a display terminal. Input ports of the software client are connected to a human body physiological signal collection device (in a wired or wireless manner); a user wears the collection device, and communication ports of the client are respectively connected to communication ports of a display module by means of a multichannel communication module. Firstly, the system is initialized, and then starts to run based on a control method of visual stimulations (an object flicker or distortion). If a target is a text input target, an interface is switched to a text input interface, and texts are inputted by using a physiological signal detection algorithm for a human body. If the target is not a text input target, the type of information is determined by using a detection algorithm of a specific physiological signal and visual stimulation feedback information, so as to complete the interaction. Search and switching can be performed among text input boxes, selection options and multiple directories, and a bottom layer of the directories can be reached, so as to select a target.
