Human eye gaze is a strong candidate to create a new application area based on human-computer interaction. To implement a really practical gaze-based interaction system, gaze detection must be realized without placing any restriction on the user's behavior or comfort. This paper describes a gaze tracking system that offers freehead, simple personal(More)
In this paper we introduce a novel gaze tracking system called <i>FreeGaze,</i> which is designed for the use of everyday gaze interaction. Among various possible applications of gaze tracking system, Human-Computer Interaction (HCI) is one of the most promising elds. However, existing systems require complicated and burden-some calibration and are not(More)
We propose a gaze movement model that enables an embodied interface agent to convey different impressions to users. Managing one's own impression to influence the behaviors of others plays an important role in human communications. To create a new application area which involves agents in this kind of social interaction, interface agents that manage their(More)
We propose a head-free, easy-setup gaze tracking system designed for a gaze-based Human-Computer Interaction. Our system enables the user to interact with the computer soon after catching the user's eye blinks. The user can move his/her head freely since the system keeps tracking the user's eye. In addition, our system only needs a 10 second calibration(More)
A novel gaze tracking method that requires only one calibration marker for personal calibration is proposed. In general, personal calibration is known to be a troublesome task, which requires the user looks at nine to twenty calibration markers in succession. Unlike traditional methods, the proposed method drastically reduces the cost of personal(More)
Many studies have explored the issues of interruption and availability in workplace environments, however, few have focused on human interruptibility in home environments. To make the initiation of online remote communication smoother, determining if it is appropriate to interrupt the remote communication partner is critical. As a preliminary investigation(More)
The authors employ behavioral theories of human motivation and affect and present an explanation for why some CSCW experience is satisfying and engaging for a user. In a longitudinal experiment, participants were divided into four groups and solved two open-ended problems together using a video-conference system. Traditional metrics of usability and product(More)
