Artificial eye simulation device suitable for infant eyeball movement detection

Abstract

The invention discloses an artificial eye simulation device suitable for infant eyeball movement detection. The artificial eye simulation device comprises a left artificial eyeball and a right artificial eyeball, a left universal turntable and a right universal turntable, a left translation module, a right translation module and a video display module. Each of the left artificial eyeball and the right artificial eyeball comprises a hollow eyeball body, a polyethylene film iris body covering the eyeball body and a micro camera, the eyeball body is provided with a simulated pupil, the micro camera is fixedly arranged in a hollow cavity of the eyeball body, and the camera and the simulated pupil are arranged on the same central axis of the eyeball body; the cornea reflection characteristics of human eyeballs can be truly simulated by adopting the polyethylene film to simulate the cornea; and meanwhile, the left universal turntable and the right universal turntable are controlled according to an image acquired by the micro camera to simulate a dynamic capturing function of eyeballs, and the distance between the eyeballs is changed through the left translation module and the right translation module. Therefore, the real effect of human eyes in the calibration work of the eye tracker can be simulated, and the problem that infants or some children with eye diseases cannot complete the calibration of the eye tracker is solved.

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 detecting eyeball movements of infants. 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 in cli...
