Title: System and method for acquiring and drawing hand skeleton on document image for telepresence, calculation execution method, program, and computer system
Inventor: CHUL-HWAN KIM
IPC: G06T1/00
Filed: 2019-08-20
Abstract: To follow a part of a document being discussed in a telepresence scene where a document or a slide is discussed with a remote user.SOLUTION: One way to deal with this problem is to provide feedback indicating where in the document a user's hand points. By doing so, it becomes possible to have a dialogue with gestures that is richer in expression than a simple remote cursor. A critical practice issue is how to efficiently transmit this remote feedback with a high resolution document image. This is not possible with standard video conferencing systems due to insufficient resolution. The inventors propose a method of using hand skeletons for feedback. The skeleton can be captured using a depth camera or a webcam (with a deep network algorithm) and can transmit small data at high frame speeds (without video coding).SELECTED DRAWING: Figure 4
