During patient consultations by videoconferencing, clinicians often sit as close as 1 m from the videoconferencing units, creating a significant eye gaze angle (i.e. the angle between the eye and the camera, and the eye and the centre of the display). Eye gaze angle may adversely affect the satisfaction with videoconferencing. Four videoconferencing environments were examined: desktop PC, portable telehealth unit, videoconferencing room, and a boardroom equipped with a ceiling-mounted camera and a projection screen. Two still images of each of the three subjects were captured: one at a 7 degrees eye gaze angle and the other at 15 degrees. Each of 53 observers ranked four pairs of images for each of the three subjects. In 87% of cases, the observers perceived better eye contact at an eye gaze angle of 7 degrees than 15 degrees. Also, 92% of observers responded that the difference in the perceived eye contact was important to them as patients. Improved eye contact can be realized by increasing the horizontal distance of participants from the videoconferencing unit.
在通过视频会议进行患者咨询时，临床医生常常距离视频会议设备仅1米之遥，从而形成了较大的视线夹角（即眼睛与摄像头以及眼睛与显示屏中心之间的夹角）。视线夹角可能会对视频会议的满意度产生不利影响。研究人员考察了四种视频会议环境：台式电脑、便携式远程医疗设备、视频会议室以及配备了天花板摄像头和投影屏幕的会议室。对三名受试者分别拍摄了两张静态图像：一张是视线夹角为7度时拍摄的，另一张是15度时拍摄的。53名观察者对三名受试者的四组图像进行了排序。在87%的情况下，观察者认为7度视线夹角时比15度时的眼神交流更好。此外，92% 的观察者表示，他们作为患者，感觉到的眼神交流差异对他们很重要。通过增加参与者与视频会议设备之间的水平距离，可以改善眼神交流。
