Embodiment Construction

[0022] A method of automatically tracking the movement of a user participating in a video chat application and displaying consecutive frames of images of the user is disclosed. A capture device coupled to the computing device captures the user within the field of view of the capture device. A sub-frame of pixels containing the user's head, neck, and shoulders is identified in the capture frame of the capture area captured by the capture device. The sub-frame of pixels is displayed to a remote user at the remote computing device who is participating in a video chat application with the user. In one embodiment, the capture device also detects more than one user in the capture area and automatically adjusts the pixel subframe to include all users. A sub-frame of pixels identifying the user's head, neck, and shoulders is displayed to the remote user at the remote computing system. In this way, a better user experience is provided between users of the video chat application, wher...

Abstract

The invention relates to automatically tracking user movement in video chat application. A system for automatically tracking movement of a user participating in the video chat application executing in a computing device is disclosed. A capture device connected to the computing device captures a user in a field of view of the capture device and identifies a sub-frame of pixels identifying a position of the head, neck and shoulders of the user in a capture frame of a capture area. The sub-frame of pixels is displayed to a remote user at a remote computing system who is participating in the video chat application with the user. The capture device automatically tracks the position of the head, neck and shoulders of the user as the user moves to a next location within the capture area. A next sub-frame of pixels identifying a position of the head, neck and shoulders of the user in the next location is identified and displayed to the remote user at the remote computing device.

Description

technical field [0001] The present invention relates to video chat applications, in particular to automatically tracking user movement in video chat applications. Background technique [0002] Video communication systems, such as video conferencing systems and video chat systems, provide multiple participants at different locations with the ability to communicate with each other. Video communication systems can utilize web cameras and microphones to capture audio / video content and transmit the content to other users over the network in real time. However, video communications typically require the user to remain still in front of the camera while communicating with the remote user at the remote computing device. Any movement of the user typically causes the user to no longer be optimally viewed by the remote user at the camera and remote computing device. Contents of the invention [0003] Disclosed herein is a method and system by which a user participating in a video c...
