The invention provides a human-computer
interaction method. The human-computer
interaction method comprises the following steps of: (1), detecting key points of eyes including upper and lower eyelids, inner circles and outer circles of irises and
pupil centres, fitting to obtain position information of boundaries of the upper and lower eyelids,
canthus and boundaries of the inner circles and outer circles of the irises, and obtaining accurate pupils and iris centres through information of the inner circles and outer circles of the irises; (2), calculating the direction of eyeball
sight, and, in combination with the position of the
sight correspondingly on a display screen of
virtual reality equipment, completing eyeball
sight tracking; (3), performing stare /
blink detection of eyeballs including stare detection and
blink detection, if stare /
blink detection is passed, entering the step (4), and otherwise, entering the step (5); (4), executing corresponding operations for specific stare items in stare detection, and then, returning to the step (1) to perform detection of the key points of the eyes; and (5), according to the eyeball sight direction, updating a display content of the
virtual reality equipment, and then, returning to the step (1) to perform detection of the key points of the eyes.
