Results of study aimed to evaluate the difficulty in maintaining eye contact during a teleconference for different camera-gaze angular offsets will be presented. Videoconferencing systems may compromise the eye contact between participants due to imperfect angular alignment between the center of the screen and the camera. The effect of camera-gaze angular offset was quantified by assessing Effectiveness and Engagement ratings. It was shown that even 10 degrees of misalignment cause a statistically significant drop in Effectiveness for business-type teleconference calls. Our research results can be practical in conferencing equipment design and setup, modern telecommunication equipment design, workplace ergonomics, or distance learning equipment setup.
