Eye tracking is the process of measuring either the point of gaze or the motion of an eye relative to the head. Cognitive neurosciences has emphasized the importance of eye movements in carrying crucial information about emotional states of others. As face perception is a basic process in interpersonal communication. The facial gaze pattern of human face experiment was performed. Twenty-two subjects, all right handed, aged 25.5 ± 5.4 yrs (females =16), from visiting graduate students to NIOH and staff of NIOH were recruited. On eye tracking experiment with spontaneous gazing of neutral face photograph, majority of subjects gazed at upper half of face near bilateral eye region of the face, on focus map analysis, gaze maps, as well as on heat map analysis. Study revealed the pattern of human face perception and reiterated the results of earlier western studies among young subjects from India. Introduction: Most of the surroundings information is taken from the eyes, and with a lesser extent from other sensory inputs. Thus the external world is explored predominantly through visual perception. During …show more content…

An eye tracker is a device for measuring eye positions and eye movement. Recent reports from the social-cognitive neurosciences have emphasized the importance of eye movements in carrying crucial information about emotional states of others (Kliemann, Dziobek, Hatri, Steimke, & Heekeren, 2010). An amount of eye gaze has been reported to be predictive of one’s ability to interpret the intentions of others and the meaning of social situations. As face perception is a basic process in interpersonal communication (Haxby, Hoffman,, & Gobbini, 2002). In the current study, pattern of facial gaze processing of young subjects on viewing faces with neutral expression was performed to understand the patterns of spontaneous human face
