摘要
The present invention relates to an eye tracking device using CA-POMDP for robust human computer interaction. Also, according to the present invention, the eye tracking device includes: an eye tracking module binarizing an eye image by a binary threshold after extracting an eye area when a face image is input and tracking eyes by tracking the position of pupils in the eye image binarized, wherein the eye tracking module also outputs a compensation value on a control action of a system control parameter; an image quality evaluating module providing an image quality label by evaluating image quality by receiving the face image; and a CA-POMDP module defining the system control parameter in a state and forming a word context model by combination of various objects by the each image quality label. The CA-POMDP module also determines a current state based on information on the word context model expressed by using properties of the various objects and property values in accordance with the image quality label provided from the image quality evaluating module. The CA-POMDP module adjusts the system control parameter which can be executed based on the determined current state and renews an action function value based on the compensation value of the control action of the system control parameter. The CA-POMDP selects the optimal control action of the system control parameter in accordance with the renewed action function value.
