![]() ![]() It is dominated by the current needs for visual high-detail information, when the high-resolution area of the human retina, the fovea, is aligned with the sought-for visual input (for an overview, see Tatler et al., 2011).Īlthough looking behavior is primarily instrumental for the looker, it is additionally also communicative (Kendon & Cook, 1969). In general, gaze direction is determined by the ongoing and dynamically changing aspects of the looker’s task (Schneider et al., 2013). Size perception definition software#For the present context, a video conference is conceived of as a substitute for an in-person meeting between two or more participants, usually using a video camera and a screen (often integrated in a laptop computer, a tablet, or a smartphone) for each participant, and a software application that transmits the video stream via the internet, distributes them among the participants, and organizes the visual presentation of the streams on the participants’ screens.Ī common problem within this setting is gaze direction. Video conferences have become an everyday activity in recent years. The paper concludes with some recommendations for a setup of video conference systems, optimized for perceived gaze contact. Size was found to increase the gaze cone. A second experiment tested the effect of size on the perception of horizontal gaze directions. Optimal gaze direction was somewhat higher for tiles at the bottom of the screen. The results showed that a slightly upward directed gaze was optimal for the direct gaze judgment, with a width of ± 4 degrees. Furthermore, the position of the tile on the screen varied. If the listener feels looked at when the speaker looks into the camera, how tolerant is the listener for slight deviations? And does this depend on the position of the speaker’s tile on the screen, or the size of the tile? In a first experiment, participants from a student population judged whether they are looked at, while vertical gaze direction of the looker was varied. In a video-conference setting, where multiple participants are on the screen, things are complicated and not necessarily optimal. ![]() In face-to-face communication, it is common that speaker and listener intermittently look at each other. ![]() A common problem in video conferences is gaze direction. ![]()
