Visual drive control method and apparatus with multi phase encoding

摘要

A visual drive control method with multi-phase encoding includes the following steps. A plurality of flickering sequences are generated by an encoding process according to a reference phase and a plurality of shifting phases divided in time division under at least one phase shift state, then a display unit is driven to display corresponding optical images. An optic nerve of an organism is evoked by the optical images, such that the organism generates a corresponding biological signal. Next, a computation process is performed to a digital biological signal converted from the biological signal to acquire an average captured reference phase and an average captured shifting phase of the digital biological signal. Then, the frequencies and the phase states of the digital biological signal and the flickering sequences are compared to output a corresponding control signal. A visual drive control apparatus with multi-phase encoding is disclosed herein.

1. A visual drive control method with multi-phase encoding, comprising:
generating a plurality of flickering sequences by an encoding process according to a reference phase and a plurality of shifting phases divided in time under at least one phase shift state; driving a display unit by the flickering sequences to display a plurality of optical images corresponding to the flickering sequences; evoking optic nerve of an organism by the optical images such that a biological signal corresponding to the optical images is generated by the organism; converting the biological signal to a digital biological signal; performing a computation process to the digital biological signal to acquire an average captured reference phase corresponding to the reference phase, of the digital biological signal, and to acquire an average captured shifting phase corresponding to one of the shifting phases, of the digital biological signal; and comparing frequencies and phase states of the digital biological signal and the flickering sequences to output a corresponding control signal.
