“…In diagnostic applications EGTs are used to quantify a user's attention, while in interactive applications EGTs are used to interact with the user for use in a device or computer [3]. According to the distance between the EGT capture device and the human subject's eyes, EGT systems are categorized into Remote Eye and Gaze Tracking systems (REGT) and Head Mounted Eye and Gaze tracking systems (HEGT).…”

“…The study of this originated from the field of psychology has now gained popularity within the field of computer science and in particular, Human-Computer Interaction (HCI). The fundamental goal of eye and gaze tracking is to estimate the direction of gaze of a person [3], and its output should be an estimation of the projected point of view with regards to the person [2]. An ideal eye gaze tracker should be accurate, reliable, robust, non-intrusive, operate as close to real-time as possible, be robust to head motion vibrations, and not require complex calibration procedures [3].…”

Abstract. A virtual avatar or autonomous agent is a digital representation of a human being that can be controlled by either a human or an artificially intelligent computer system. Increasingly avatars are becoming realistic virtual human characters that exhibit human behavioral traits, body language and eye and head movements. As the interpretation of eye and head movements represents an important part of nonverbal human communication it is extremely important to accurately reproduce these movements in virtual avatars to avoid falling into the well-known "uncanny valley". In this paper we present a cheap hybrid real-time head and eye tracking system based on existing open source software and commonly available hardware. Our evaluation indicates that the system of head and eye tracking is stable and accurate and can allow a human user to robustly puppet a virtual avatar, potentially allowing us to train an A.I. system to learn realistic human head and eye movements.

“…In the gaze-estimation block, the glints and pupil positions are used as input to the function that estimates the gaze-point coordinates in the screen. Generally, a second-or third-order polynomial is selected as the gaze estimation function based on unknown coefficients [26][27] in which glints and pupil center positions are used as input variables:…”

Abstract-A new system is presented that enhances the interoperability between a video-oculographic (VOG) system for mouse movement control and an electromyographic (EMG) system for mouse click detection. The proposed VOG-EMG system combines gaze and muscle information to minimize the number of undesired clicks due to involuntary activations and environmental noise. We tested the system with 24 subjects, comparing three different configurations: one in which the VOG and EMG systems worked independently and two in which we used VOG gaze information to improve the EMG click detection. Results show that the number of false-positive click detections can be reduced when VOG and EMG information is combined. In addition, the third configuration, including extra processing, can reduce the activation delay produced because of the combined use of the VOG and EMG systems. The new VOG-EMG system is meant to be used in noisy environments in which the number of false clicks may impeach a reliable human-computer interaction.
