Gaze estimation based on camera relay
Gaze-tracking is a hot technology of human-computer interaction, which requires an explicit personal calibration process before every use for the sake of higher accuracy. When a number of different gaze interactive systems are used continuously, the calibration process would take the trouble. Due to the accuracy of interaction relying on the calibration of the camera which is used, in this paper, we proposed a method to transmit the personal calibration information based on camera calibration. The system devotes to deliver the personal calibration information between gaze interactive systems so that only one calibration is needed for the multiple gaze interactive systems. Given the calibrated cameras in the interactive systems, personalized eye parameters calibrated on one camera can be transmitted to any of the other cameras one by one. When one of the other cameras is used, the personal calibration process can be omitted without lowering the accuracy of the premise of the calculation much, where implements multiple interactive systems to realize the seamless transfer to use. Experiment between the two cameras is explored to validate the method we proposed. The experimental results show that the method is feasible and reliable.
