Software solution to completely wireless presentation

Recent technology advances have made laptops tether-free, longer battery life enables a laptop to run for hours without a power cord, and wireless communication lets a laptop connect to a network without a network cable. However, in some cases, a cable is still needed to connect the laptop to a specific device. For example, a speaker has to use a video cable to connect the laptop to an overhead projector to make a presentation, although the laptop has wireless access capacity and the conference room has the wireless access point. This is mainly due to the lack of appropriate software. A lot of time is wasted connecting and disconnecting physical cable. The paper discusses a software solution which projects an application running on a laptop wirelessly onto the computer connected to an overhead projector. A prototype system has been implemented based on that idea. With this wireless presentation system, a speaker can immediately access the overhead projector without using a single physical cable. As a result the time saved is substantial.
