Supervised Gaze Bias Correction for Gaze Coding in Interactions

Abstract

Understanding the role of gaze in conversations and social interactions or exploiting it for HRI applications is an ongoing research subject. In these contexts, vision based eye trackers are preferred as they are non-invasive and allow people to behave more naturally. In particular, appearance based methods (ABM) are very promising, as they can perform online gaze estima- tion and have the potential to be head pose and person invariant, accommodate more situations as well as user mobility and the resulting low resolution images. However, they may also suffer from a lack of robustness when several of these challenges are jointly present. In this work, we address gaze coding in human-human interactions, and present a simple method based on a few manually annotated frames that is able to much reduce the error of a head pose invariant ABM method, as shown on a dataset of 6 interactions.

Male gaze

In feminist theory, the male gaze is the act of depicting women and the world in the visual arts and in literature from a masculine, heterosexual perspective that presents and represents women as sexual objects for the pleasure of the heterosexual male viewer. In the visual and aesthetic presentations of narrative cinema, the male gaze has three perspectives: (i) that of the man behind the camera, (ii) that of the male characters within the film's cinematic representations; and (iii) that of the spectator gazing at the image.

Eye tracking

Eye tracking is the process of measuring either the point of gaze (where one is looking) or the motion of an eye relative to the head. An eye tracker is a device for measuring eye positions and eye movement. Eye trackers are used in research on the visual system, in psychology, in psycholinguistics, marketing, as an input device for human-computer interaction, and in product design. In addition, eye trackers are increasingly being used for assistive and rehabilitative applications such as controlling wheelchairs, robotic arms, and prostheses.

Eye movement in reading

Eye movement in reading involves the visual processing of written text. This was described by the French ophthalmologist Louis Émile Javal in the late 19th century. He reported that eyes do not move continuously along a line of text, but make short, rapid movements (saccades) intermingled with short stops (fixations). Javal's observations were characterised by a reliance on naked-eye observation of eye movement in the absence of technology.
