探討彈性顯示方式

Abstract

如何取代傳統的顯示方式，如LCD(Liquid Crystal Display)或CRT(Cathode Ray Tube)，一直是人機互動(Human Computer Interaction)一個很重要的議題。 本論文透過以投影機(Projector)代替傳統顯示方式，透過雙手在投影機投出的影像下模擬滑鼠行為的方式，探討新的顯示方式的可行性、困難和帶給使用者的影響。 本論文以攝影機(Camera) – 投影機(Projector)為基礎的架構，提供一套以雙手模擬滑鼠行為的系統。 系統以投影機代替傳統顯示方式，將傳統顯示器的影像透過投影機投在桌面或牆上，利用攝影機捕捉右手在投影機投出影像中的移動作為滑鼠的游標移動；左手拿著標記(Token)當作滑鼠指令，如:左鍵雙擊、右鍵單擊，透過訊息傳遞方式與微軟系統溝通。透過這樣的方式，探討新的顯示方式的可行性、困難和帶給使用者的影響。

It is always an important issue to substitute the traditional display, like LCD(Liquid Crystal Display) or CRT(Cathode Ray Tube) in the HCI(Human Computer Interaction). The thesis provides a system which is based on the camera and projector to simulate the mouse actions. The system uses projector to substitute the traditional displays. It projects the images form the traditional displays on the desk or the wall. The camera catches the motion of the right hand in the image as mouse cursor and tokens in the left hand as the instructions of the mouse, like double click or pop out menu. We can explore the difficulty and convenient for users through this system.
