碩士 === 國立交通大學 === 電資學院學程碩士班 === 90 === The purpose of this thesis is to improve conventional presentation method. Our new method replaces VGA cable and Infrared remote controller by the IEEE 802.11 wireless network technology in computer-based iProjector. Slider and projector are two most useful devices in presentation. Both of them evolved from the previous traditional overhead projector. Although these two devices are still being used, yet it does not mean that they will be used forever. The speed of machine evolution is more quickly now than ever. There appear several new methods. The weight of laptop PC and portable data projector are not heavy. We find that PowerPoint document makes presentation easier. In order to be cable-free, we propose a new approach based on a PDA and wireless computer projector. We study the properties of IEEE802.11 Ad Hoc mode and PowerPoint Viewer, find out all of API functions in Personal Digital Assistant such as Pocket PC, adapt API functions, propose our idea, control it and also implement the system in an iProjector prototype. Our conclusion is getting an approach method that uses a cable-free projector in the IEEE802.11 Ad Hoc mode.
