To obtain a natural view of the operation room and autonomous image selection and transformation during tele-surgical operation, we propose a telemonitoring system which is composed of two types of camera systems. One is an active camera system controlled by surgeon’s gesture and gaze direction to obtain natural view image. Another is a fixed camera system that is composed of multiple cameras a...

Gaze estimation plays a significant role in understating human behavior and human–computer interaction. Currently, there are many methods accessible for gaze estimation. However, most approaches need additional hardware data acquisition which adds an extra cost to tracking. The classic tracking usually require systematic prior knowledge or expertise practical operations. Moreover, they fundamen...

Given the high relevance of visual input to human behavior, it is often important to precisely monitor the spatial orientation of the visual axis. One popular and accurate technique for measuring gaze orientation is based on the dual search coil. This technique does not allow for very large displacements of the subject, however, and is not robust with respect to translations of the head. More r...

Purpose We compared cone density measurements derived from the center of gaze-directed single images with reconstructed wide-field montages using the rtx1 adaptive optics (AO) retinal camera. Methods A total of 29 eyes from 29 healthy subjects were imaged with the rtx1 camera. Of 20 overlapping AO images acquired, 12 (at 3.2°, 5°, and 7°) were used for calculating gaze-directed cone densities...

Head-mounted video cameras (with and without an eye camera to track gaze direction) are being increasingly used to study infants' and young children's visual environments and provide new and often unexpected insights about the visual world from a child's point of view. The challenge in using head cameras is principally conceptual and concerns the match between what these cameras measure and the...

People with autism spectrum disorder (ASD) show atypical attention to social stimuli [1] and gaze at faces [2] and complex images [3] in unusual ways. But all studies to date are limited by the experimenter's selected stimuli, which are generally photographs taken by people without autism. What might participants with ASD show us if they were the ones taking the photos? We gave participants a d...

Western feminist film theory was formed in the 1960s and 1970s it has been widely discussed since then. With help of Freud’s psychoanalysis, Laura Mulvey analyzes interweaving erotic pleasure film, its meaning, central place image woman. At same time, improvement technology photography methods provide more chances for female spectators to seek as counterparts films. The lesbian is a category th...

This thesis deals with gaze behaviour in human-human interactions. The aim of this work was to study and statistically analyse gaze direction during dialogues in order to suggest possible explanations about the role of gaze in social interactions. Previous research on gaze behaviour showed that visibility improved information transfer during human-human interaction. Recent works concentrated on...

EOG is a biosignal which occurs during eye activities such as eye movement and blink. EOG has a linear relationship with gaze distance. Detection object position in 3-dimensional area using gaze motion was proposed in this research. To calculate the distance of gaze motion in pixel unit, affine transform method was developed. The homogeneous matrix from five geometry processes: transformation-1...
