Patent ID: 11468789

Abstract:
The invention discloses an electroencephalogram-controlled video input and auditory display blind guiding apparatus and method. The apparatus includes a video acquisition module, an electroencephalogram acquisition module, a processor and an audio playback module. The video acquisition module is connected to the processor, the electroencephalogram module is connected to the processor and configured to acquire an electroencephalogram signal, the audio playback module is connected to the processor, and the processor is separately connected to the video acquisition module, the electroencephalogram acquisition module and the audio playback module. According to the present invention, control of a region of interest in the blind guiding apparatus is achieved by means of the electroencephalogram signal, so that sensing a whole image and sensing details of interest in the image are switched conveniently. A region of interest in a current video is set by using the electroencephalogram, a flexible auditory display resolution and a control method are provided for a user, and the user can sense global information or local detail information of the image with the setting of the region of interest, so that the defect of low auditory display resolution is overcome effectively. The invention can be widely applied to different occasions where blind guiding is required.
