Embodiment Construction

[0060] Such as figure 1 As shown, a device for realizing human-computer information interaction based on eye movement recognition, the device includes a camera, a distance sensor, a gravity sensor or a gyroscope, a memory and a processor. The camera is used to capture a certain range of images in front of the mobile terminal at a time interval of 30ms. The distance sensor is used to obtain the distance between the mobile terminal and the face when judging the validity of the picture and checking the parameters when starting up; the gyroscope is used to When judging the validity of the picture and the power-on verification parameters, the position of the mobile terminal in space is obtained, that is, the angle a and the direction between the front of the mobile terminal and the reference plane are obtained; the memory is used to store the image data captured by the camera, as well as the image information and The data required for image preprocessing, including: face pictures, ...

Abstract

The invention relates to a device and a method for implementation of man-machine information interaction based on eye motion recognition. The device comprises a camera, a distance induction instrument, a gravity induction instrument or gyroscope, a memory and a processor. The camera regularly shoots images in front of a mobile terminal within a certain range, and the distance induction instrument acquires the distance between the mobile terminal and a face when validity and startup verification parameters of the images are judged. The gyroscope acquires directions and an included angle a between the front face of the mobile terminal and a datum plane. The memory stores image data, image information and data required by image preprocessing. The processor processes data of each module including an image acquisition module, an image validity judgment module, an eye image extraction module, a pupil center position analysis module, a pupil center position sequence acquisition module, a position sequence analysis module and a motion processing module. The device and the method for implementation of man-machine information interaction based on eye motion recognition bring brand-new experience to users, and the users can freely control the mobile terminal only by moving eyeballs, so that higher humanization is realized.

Description

technical field [0001] The invention belongs to the technical field of mobile communication terminals, and in particular relates to a device for realizing human-computer information interaction based on eye movement recognition. The invention also relates to a method for realizing human-computer information interaction based on eye movement recognition. Background technique [0002] In the era of information technology explosion, human-computer information interaction involves many fields, such as PC, mobile phone, etc. In the past, it was keyboard interaction, which required memorizing many commands and codes, which was very inconvenient to operate; It is convenient and fast to move the mouse to complete some operations; until today, the appearance of touch screen has brought great changes to people's life, and touch screen technology has also been widely used. Most of the mobile terminal devices now use touch screens, and the touch screens are more user-friendly to operat...
