A video telephone headset device includes a foundation which supports an image capture device, a support arm, and a convex mirror. When the foundation is held adjacent to a user's head, the support arm positions the convex mirror in a fixed position in front of the user's face. The mirror reflects the full facial image to the image capture device. This arrangement makes it possible to construct a video telephone headset which is simple and small in size yet able to capture the full face and facial expressions using very little bandwidth. |

DETAILED DESCRIPTION I claim: 1.
A method for simulating eye-to-eye contact in a videoconference, including the steps of: displaying an image of a remote face on a local display, said local display located in a first position; collecting an image of a local face through a camera located in a second position, said second position offset from the line of sight directed from said local face toward said first position; and, shifting the viewing perspective point of said camera in said collected image from said second position to a third position, said shift including a lateral component such that said third position is adjacent to said line of sight from said local face to said first position, whereby said camera can remain visually unobtrusive and said lateral shift in perspective allows the view collected by said visually unobtrusive camera to appear to be from a perspective point located on said line of sight such that eye-to-eye contact is simulated.
2.
The method of claim 1, wherein said camera is a head-mounted face-capture camera, and the step of collecting said image of said face is through said head-mounted face-capture camera.
3.
The method of claim 1, further comprising the step of: abstracting a parametric image model representation of said image of said local face.
4.
The method of claim 3, wherein said shift includes a component in the direction of the line of sight, from a proximate perspective to a distal perspective, such that said third position is more distant from said local face than said second position, whereby said head-mounted face-capture camera can capture an image of said face with a reduced perspective distortion.
5.
The method of claim 3, further comprising the step of: retrieving from storage predetermined data representative of the position of said head-mounted face-capture camera with respect to said face.
6.
The method of claim 1, further comprising the steps of: retrieving from storage three-dimensional data corresponding to the contours of a face; and applying a transform to the image of said remote face based on said three-dimensional data
