摘要:基于嵌入式系統,通過(guò)引入擴展接口、添加記錄設備并提出新穎的工作方式來(lái)對傳統的投影設備進(jìn)行改進(jìn)。利用改進(jìn)后的系統,講演者不僅可以通過(guò)網(wǎng)絡(luò )交互地控制幻燈片的播放,擺脫頻繁插拔VGA線(xiàn)的不便,還可以只通過(guò)一支普通廉價(jià)的激光筆就控制整個(gè)講演過(guò)程以及對幻燈片內容添加注解。除此之外,我們的系統僅利用很小的存儲空間,即可記錄包括講演者聲音、激光點(diǎn)的移動(dòng)、添加的注解和幻燈片播放進(jìn)度在內的整個(gè)報告講演的過(guò)程,同時(shí)在占用較小網(wǎng)絡(luò )帶寬的情況下將整個(gè)過(guò)程向遠程的客戶(hù)端直播。

Abstract:This design adopts embedded-system design to upgrade the traditional projector,by introducing extended ports and recording devices,as well as brand-new operating method. With the upgraded design,projector user can interactively play PowerPoint slides over LAN/WLAN linkwithout plugging and dragging the awkward VGA cable, and control presentation progress as well as annotate directly using a cheap laser-pointer. Besides, the new device can record the whole presentation with high-quality (including voice,pointer movement,annotation,and presentation progress) into a very small file,or concurrently broadcast the presentation over the internet to remote client PCs using limited bandwidth.
Keywords:Presentation device, Gesture recogination, Human-machine interaction, remote control
