技術摘要:
一種互動式多點觸控電腦系統,包含一供光線部分穿透且部分反射的互動板、一影像擷取裝置、一物件資料庫、一處理器及一投影裝置。物件資料庫中的物件識別資料包括一對一實體物件所作的特性描述及對應該特性描述的一控制指令。處理器針對影像擷取裝置所擷取之影像與該等特性描述比對,當比對符合,則判斷為有實體物件接觸互動板,並計算實體物件之座標,且執行該特性描述所對應之控制指令。投影裝置將控制指令執行結果投影至互動板。藉此,使用者可藉由將預設之實體物件擺放到互動板上,甚至旋轉、移動實體物件而使電腦系統產生預設之互動反應。
An interactive multi touch computer system includes an interactive board that is partially light transmissible and that is partially reflective, an image capture device, an object database, a processor, and a projector. Object identified data in the object database includes a characteristic description of a physical object, and a control instruction corresponding to the characteristic description. The processor compares the image captured by the image capture device with the characteristic description, if they match each other, the processor concludes that the physical object contacts the interactive board, and computes coordinates of the physical object. Then, the processor executes the control instruction corresponding to the characteristic description. The projector projects the result of the execution of the control instruction to the interactive board. Therefore, an user can enable the computer system to perform a predetermined interactive reaction by putting the physical object on the interactive board or by rotating or moving the physical object on the interactive board.
