Path generation in virtual reality environment based on gaze analysis

Abstract

In this paper the gaze point and gaze line were used for generation of the path of a mobile robot in an immersive virtual environment. The gaze point is considered the intersection of the lines of sight of the two eyes. The experiments were conducted in computer generated virtual reality environment using polarized glasses. The virtual scene was projected in front of the user on a 3D stereoscopic visualization screen. The user was immersed in the environment through polarized glasses and a head-mounted eye tracking device was placed on the head of the user. The floor of the environment was tilted to reproduce the real floor position relative to the user's head when they are seated in a wheelchair. In the first part is presented the evaluation of the accuracy of the estimated gaze point, followed by the results of the experiments on path generation in virtual reality environment based on gaze analysis.

Accuracy of gaze point estimation in immersive 3D interaction interface based on eye tracking

“…6). As the results in [4] indicate, the accuracy of detecting the convergence point is expected to be higher for the objects located closer to the user. The matrix of objects to be gazed was sequentially placed at 0.1 m, 0.5 m, 1 m and 1.5 m away from the user.…”

“…Step by step assistive robots are introduced into the human world to aid them in the completion of various tasks [3]. The gaze point and gaze line, measured with an eye tracking device, can be used for generating the path of a mobile robot in an immersive virtual environment [4]. Path generation of the robot (Fig.…”
