Abstract
Using gaze detection to determine image information collected from a scene. In order to determine the gaze of persons within a scene, images of the faces of those persons are obtained, and the gaze or line of sight of those persons is determined. Image information encompassing an area of the scene at which the gazes of persons at the scene are directed is then obtained. The obtained video information may be displayed in realtime, or recorded for later viewing.
Claims31
A method for controlling a video camera, comprising:
- determining a line of sight of at least one person at a first location;
- and
- obtaining an image of a first area intersected by said line of sight of said at least one person at said first location using a first imaging camera at said first location;
- obtaining an image of a face of at least one person at a second location;
- determining a line of sight of said at least one person at said second location;
- obtaining an image of a face of at least one person at a third location;
- determining a line of sight of said at least one person at said third location;
- and
- in response to determining that said line of sight of said at least one person at said first location is directed to a display at said first location and to determining that said line of sight of said at least one person at said second location is directed to a display at said second location, displaying at said first and second locations at least a portion of an image obtained by said third imaging camera at a third location.

A system for controlling a displayed image, comprising:
- a first gaze detection module, wherein a direction of a gaze of at least one person at a first location is determined;
- a first display at said first location;
- a first camera control module, wherein said first camera control module receives information related to said determined direction of a gaze of at least one person at said first location;
- a first imaging camera at said first location, wherein an output derived from said first imaging camera includes image information from an area intersected by said gaze of said at least one person at said first location;
- a second gaze detection module, wherein a direction of a gaze of at least one person at a second location is determined;
- a second display at said second location;
- a second camera control module, wherein said second camera control module receives information related to said determined direction of a gaze of at least one person at said second location;
- a second imaging camera at said second location, wherein an output derived from said second imaging camera includes image information from an area intersected by said gaze of said at least one person at said second location;
- a third gaze detection module, wherein a direction of a gaze of at least one person at a third location is determined;
- a third display at said third location;
- a third camera control module, wherein said third camera control module receives information related to said determined direction of a gaze of at least one person at said third location;
- a third imaging camera at said third location, wherein an output derived from said third imaging camera includes image information from an area intersected by said gaze of said at least one person at said third location, wherein in response to determining that the area intersected by said gaze of said at least one person at said first location is directed to said display at said first location, and in response to determining that the area intersected by said gaze of said at least one person at said second location includes said display at said second location, at least a portion of an image obtained by said third imaging camera at said third location is displayed by said first display and said second display.
