Eye-Tracking Analysis of User Behavior with an Active Display Interface

Various kinds of audio/video communication systems have been developed and are available today. These systems could offer an identical environment for remote communication just as a face-to-face meeting. However, two critical issues are pointed out. One is lack of existence for remote participants and the other one is lack of relationship with remote participants. This study proposes an idea of active display interface for remote communication system called ARM-COMS (ARm-supported eMbodied COmmunication Monitor System) to tackle these issues. The concept of an active display is to enhance the existence of a digital object shown in the screen by physical movement of the display. The idea of ARM-COMS comes from this concept, and enhances the existence of a remote person by mimicking the physical movement of the remote person using the active display. In addition to this basic feature, ARM-COMS shows the relationship with the remote person by an entrainment control of the active display. This research investigates how users interact with the active display using eye-tracking and motion tracking experiments, and gain insight into user behavior to study the effectiveness of ARM-COMS. This paper presents the initial results of entrainment control and discusses the future works.
