Research on Visible Light Communication Control System Based on Steady-State Visual Evoked Potential

Using electroencephalogram to control the external device is a new type of human-computer interaction. The visible light communication technology is a new kind of wireless communication technology with broad application prospects. Therefore, this system carries out a study on visible light transmission control system on the basis of steady-state visual evocation and designs a new way for steady-state visual evoked potential to control the home terminal. The system adopts single chip microcomputer and LED lights to design the visual stimulator, and on LABVIEW platform it uses the power spectrum for estimation and real-time extraction of the vectors of evoked potential and produce the control commands of brain-computer interface, which transmit through the visible light emission module to the free space, and then receive and decode the visible light in the home network terminal, and finally achieve the control of the family terminal.
