Abstract

The method involves displaying objects being associated with a function unrelated to calculation of calibration parameters on a display of a computing device. Eye movement information associated with a user is determined when the objects are displayed, where the eye movement information indicates eye movement of eye features associated with an eye of the user. The eye movement information is associated with an object location of the objects. The calibration parameters are calculated based on the object location being associated with the eye movement information.
Method for facilitating eye tracking control calibration for a user of a computing device during personal identification number entry. Uses include but are not limited to a personal computer, a smartphone, a personal digital assistant (PDA), a mobile phone or a cellular telephone, a web appliance, a computing tablet or a tablet PC, an electronic reader, a TV, a set-top box, a laptop, a desktop computer, a display device and a head-mounted display.
The method enables filtering out visible light using an infrared pass filter such that field of view and depth of view of lenses of cameras in a camera module can allow the user to move around to accommodate for head pose variance of the user and an eye tracking control software can analyze images taken by the camera module to provide screen coordinates, thus improving image quality, while allowing number of users to use an eye tracking system at a given time, and hence increasing accuracy of eye tracking control calibration in a quick and efficient manner.
