Abstract
A pointing-control system for multipoint conferences includes a plurality of computers, a gateway, a display, a conference-control module and a pointing-control module. The computers are connected through a wired or wireless network with the gateway. The computer with the highest priority number is defined as the host computer having the right to assign any of the computers to be the report computer. The conference-control module can demonstrate a presentation frame of the report computer on the display through the gateway. The pointing-control module is used to capture pointing coordinates of pointing apparatuses of the respective computers, and further to display the pointing coordinates on the presentation frame of the display.
