Abstract
A presentation server establishes a network connection with a presentation device and a client device. The presentation server is able to receive frame data transmitted by the presentation device and pointer coordinates transmitted by the client device. Therefore, the presentation server is able to display a virtual pointer on the presentation frame according to the pointer coordinates, so that the participant can operate the pointing device of the client device to control the virtual pointer so as to participate effectively in the presentation and interact with the speaker.
