Screen display sharing system

摘要

A pointing object display technique that can manipulate a pointing object without the user being aware of a difference in display time between sites in a distributed computing environment is disclosed. It is so designed that with whatever level of time difference the receiver side receives a pointing object is displayed and confirmed using an auxiliary pointing object on the sender's screen and the positional difference on the display is absorbed. In addition, the receiver side predicts the current position of the sender's pointing object by taking the time difference on the display into account and displays a pointing object at the predicted position on the receiver's screen.
