Avatars play an important role for the embodiment of the users in virtual space communication systems. However, the conventional systems to realize the gaze have required camera-based precise eye tracking and the numbers of the users have been restricted. This paper proposes a simple substitution for the gaze control in a virtual space voice chat system. The method is to control the gaze target...

This paper discusses the image processing techniques needed to localise the iris outline in images of the eye produced by a novel, portable eye tracker. The tracker allows gaze direction to be measured by supplying simultaneous views of a subject's eye and of the world from a headmounted camera. Finding gaze direction relative to the head requires accurate and robust measurement of the iris out...

Our objective is to realize wearable interfaces for expanding our information activities in daily life. To implement these interfaces, we employ vision-based systems, including a variety of camera, a head-mounted display and other visual devices. In this paper, we present two wearable vision interfaces; 1) 2D gaze-region extraction from an observed image and 2) 3D gaze-position estimation. In b...

Enhancement of computing ability of the smart phones the new use of the said device focus on the eye gaze estimation. The geometrical eye gaze estimation method measure the relation between camera, user’s eye and smart device. The illumination source on smart device generate glint on capture pupil image of the user’s eye. From the relation of glint and pupil center the eye gaze position is capt...

This paper argues for a joint development of an eye gaze -based, on-line communication aid running on a standard PC with a web -camera. Tracking software is to be provided as open source to allow for improvements and individual integrations with other aids. The interface design shall be defined by the achieved resolution of the tr acking system. The design of a type -to-talk system with 12 larg...

We present how gaze detection can be used to enhance the Rapid Serial Visual Presentation (RSVP) format, a dynamic text presentation technique suitable for mobile devices. A camera mounted on the device is used to monitor the reader’s gaze and control the onset of the text presentation accordingly. The underlying assumptions for the technique are presented together with a description of a proto...

The estimation of the human’s point of visual gaze is important for many applications. This information can be used in visual gaze based human-computer interaction, advertisement, human cognitive state analysis, attentive interfaces, human behavior analysis. Visual gaze direction can also provide high-level semantic cues such as who is speaking to whom, information on non-verbal communication a...

Gaze-following is an effective way for intention understanding in human–robot interaction, which aims to follow the gaze of humans estimate what object being observed. Most existing methods require people and objects appear same image. Due limitation view camera, these are not applicable practice. To address this problem, we propose a method following that utilizes geometric map better estimati...
