Embodiment
(embodiment 1)
Present embodiment is the method that a kind of virtual mouse is clicked, and may further comprise the steps:
1. answering electrical appliance to arrange can to photograph the camera in user's eyes zone, utilize following status image that camera takes user's eyes zone as the normal condition image: eyes are opened state, eyes closure state, the simple eye closure state of left eye, the simple eye closure state of right eye;
Concrete method is: the image of four kinds of normal conditions that photograph is changed into the gray scale array, also can directly change into 256 look formula arrays, because when opening eyes, each eyeball has obvious difference with image on every side, so have a significant array mark, and when shut my eyes, eyeball is invisible, then this significant array mark not; So each benchmark image has own discernible significant array mark.Because each user's eye condition exists than big difference, when normally watching display screen, the big or small degree that eyes are opened, the depth of eyeball color, the capital causes the significant array of eyeball different, so for for the purpose of accurately, take in advance the normal condition image preferably for each user, as reference, thus the error of effectively reducing.
In addition, also can adopt classic method, for example by measuring what mode of pupillary reflex light, judge the residing state of each eye of user, this traditional approach has been that numerous patent documentations are disclosed, and present embodiment no longer explains orally in detail to it.
2. when the display screen of electrical appliance is answered in user's binocular fixation, camera takes the realtime graphic in user's eyes zone continuously according to the default speed of taking pictures, while is more a certain width of cloth realtime graphic and normal condition image continuously, is in which kind of state thereby identify user's eyes; Concrete grammar is: by searching the having or not of the significant array mark that represents eyeball in each realtime graphic, position and quantity, can draw realtime graphic and be in which kind of state.
When identifying that the user is in that eyes are opened or eyes when closed, execution action not; When identifying the user and be in the simple eye closure state of left eye, be considered as inputting primary mouse left button click commands, when identifying the user and be in the simple eye closure state of right eye, be considered as inputting primary mouse and click instruction by right key.
