A NOVEL 3D INTERACTION TECHNIQUE BASED ON THE EYE TRACKING FOR MIXED REALITY ENVIRONMENTS

摘要

The paper describes a novel 3D interaction technique based on Eye Tracking (ET)for Mixed Reality (MR) environments. We have developed a system that integrates a commercial ET technology with a MR display technology. The system elaborates the data coming from the ET in order to obtain the 3D position of the user's gaze. A specific calibration procedure has been developed for correctly computing the gaze position according to the user. The accuracy and the precision of the system have been assessed by performing several tests with a group of users. Besides, we have compared the 3D gaze position in real, virtual and mixed environments in order to check if there are differences when the user sees real or virtual objects. The paper also proposes an application example by means of which we have assessed the global usability of the system.
