Abstract:
PURPOSE: A pupil estimating gaze apparatus and the method is provided to eliminate concern of a malfunction when staring into one point for a long time so that an installation of an infrared LED is not demanded to the around display screen. CONSTITUTION: A display unit(10) displays on a screen as fixed frequency. A pupil pickup(20) takes a photograph of a pupil of a user which information is reflected. An image data processor(30) receives screen information of the display unit and a video information recording of the pupil pickup, and presumes an eye-gaze direction of the user from two information. The pupil pickup is a high speed camera and takes a photograph of the pupil of the user with a frame rate more than two times of the screen of the display unit.
Abstract:
Disclosed are a cornea radius measurement algorithm based on geometrical optics for eye tracking and a device for measuring a cornea radius using the same. The device for measuring a cornea radius using a cornea radius measurement algorithm based on geometrical optics for eye tracking comprises a screen having a plurality of light source parts for outputting an infrared light source in a peripheral region; a camera for receiving an image of a user cornea through a reflection light source generated by reflecting the infrared light source on the user cornea; and a processing part for processing an image formed in a lens of the camera, wherein the processing part receives a first image according to the reflection light source generated by reflecting a light source outputted from a first light source part on the user cornea and a second image according to the reflection light source generated by reflecting a light source outputted from a second light source part on the user cornea, substitutes a cornea radius estimation algorithm programmed inside and measures the cornea radius of the user.
