Abstract:
In a typical desktop video-conference setup, the camera and the display screen cannot be physically aligned. This problem produces lack of eye contact and substantially degrades the user’s experience. Expensive hardware systems using semi-reflective materials are available on the market to solve the eye gazing problem. However, these specialized systems are far away from the mass market. This paper presents an alternative approach using stereo rigs to capture a three-dimensional model of the scene. This information is then used to generate the view from a virtual camera aligned with the conference image the user looks at.
