Abstract:This paper investigates gaze estimation as a cognitive process and proposes that human gaze estimation can be modelled with an average brightness mechanism, split into four sectors or in other words, a quad brightness mechanism. The aim of this paper was to confirm whether humans are indeed able to estimate gaze in a quad brightness condition and, secondly, to test their accuracy in such a condition. For this research, face images were created and manipulated to show four quadrants with average brightness. These images were run through the times 70ms, 140ms, 400ms, 600ms and 1000ms in both original and manipulated form and participants estimated the gaze orientation of each conditions faces. It was found that participants were able to estimate the gaze orientation of quad brightness images. Their accuracy was, however, somewhat worse with a deviation of 10°. In a larger context and based on the findings, it is likely that the quad brightness process models, either a section of a larger process, of gaze estimations or is part of multiple and separate processes for gaze estimations. Further research could investigate how these processes are linked, as well as the influence of head directions.
