Abstract

The invention discloses an artificial eye simulation device suitable for the calibration and detection of infant eye trackers, which comprises left and right artificial eyeballs; left and right universal turntables; left and right translation modules and video display modules; left and right artificial eyeballs; The eyeballs all include a hollow eyeball, a polyethylene film iris body covering the eyeball, and a miniature camera. The eyeball is provided with a simulated pupil, and the miniature camera is fixed in the hollow cavity of the eyeball. The camera and the simulated pupil are set On the same central axis of the eyeball; the use of polyethylene film to simulate the cornea can truly simulate the corneal reflection characteristics of the human eyeball; at the same time, according to the images collected by the micro-camera, the left and right universal turntables are controlled to simulate the dynamic capture function of the eyeball. Move the module left and right to change the distance between the eyeballs; thus, it can simulate the real effect of human eyes in the eye tracker calibration work, and solve the problem that infants or children with some eye diseases cannot complete the eye tracker calibration.

Description

technical field [0001] The invention relates to the technical field of ophthalmic diagnosis and treatment, in particular to an artificial eye simulation device suitable for calibrating and testing infant eye trackers. Background technique [0002] The eye tracker was originally used in the basic research of psychology. It studies human psychological activities by examining human eye movements, and explores the relationship between eye movement and human psychological activities by analyzing recorded eye movement data. With the advancement of technology, eye trackers can record rapidly changing eye movement data, including various measurement indicators such as gaze position, gaze time, eye saccadic direction, eye saccadic distance, and pupil diameter. The drawn eye track diagram intuitively and comprehensively reflects the spatio-temporal characteristics of eye movement. [0003] In addition to the above psychological applications, eye trackers have been gradually applied i...
