Description

觸控投影系統與其方法Touch projection system and method

本發明有關於一種投影技術，且特別有關於一種觸控投影系統與其方法。The present invention relates to a projection technology, and more particularly to a touch projection system and method thereof.

隨著電子科技的演進，人們在日常生活中，常需要利用電子裝置來執行多項工作。觸控投影系統可供使用者在投影幕進行觸控操作，投影幕的觸控操作區用以接收使用者所執行的觸控操作。在具有觸控互動功能的投影系統中，使用者可透過接觸投影幕上呈現的控制選項，以啟動投影機的對應功能。一般而言，使用者需要接觸投影幕上位於固定位置的圖示以叫出控制選單，該控制選單呈現於預設位置，使用者在該控制選單上進行觸控操作，進而執行進一步的控制操作。With the evolution of electronic technology, people often need to use electronic devices to perform multiple tasks in their daily lives. The touch projection system allows users to perform touch operations on the projection screen, and the touch operation area of the projection screen is used to receive touch operations performed by the user. In a projection system with touch interaction function, the user can activate the corresponding function of the projector by touching the control options presented on the projection screen. Generally speaking, the user needs to touch an icon at a fixed position on the projection screen to call up the control menu, which is presented in a preset position, and the user performs touch operations on the control menu to perform further control operations .

然而，在尺寸較大的觸控投影系統中，使用者需要移動位置才可接觸到投影幕的每一個角落。因此，使用者常常需要移動位置來接觸投影幕上位於固定位置的圖示，以叫出控制選單或下達使用者指令，此造成使用者使用上的不便利。舉例而言，若使用者位於投影幕的右側，且控制選單呈現於投影幕的左側，則使用者需走動才可操作控制選單，此對於使用者相當不友善。However, in a large-sized touch projection system, the user needs to move the position to touch every corner of the projection screen. Therefore, the user often needs to move the position to touch the fixed-position icon on the projection screen to call the control menu or give the user instruction, which causes inconvenience for the user. For example, if the user is located on the right side of the projection screen and the control menu is presented on the left side of the projection screen, the user needs to walk around to operate the control menu, which is quite unfriendly to the user.

In the embodiment of the present invention, the specific gesture may also include five fingers touching and clicking on the touch projection screen 110. Correspondingly, the projection device 120 can determine whether the user's touch operation is five fingers touching the touch projection screen 110 according to the number of contact points and the distance between the contact points, so as to determine whether the touch operation detected by the touch projection screen 110 is consistent Specific gestures. However, the specific gesture can be designed according to actual needs, and can also be set by the user, which is not limited by the invention.

於本發明實施例中，在步驟S204中，反應於觸控操作符合特定手勢，投影裝置120執行對應於特定手勢的投影控制功能。也就是說，使用者可透過特定手勢來控制投影裝置120執行對應的投影控制功能。於本發明實施例中，對應於特定手勢的投影控制功能，例如包含畫面擷取功能、控制選單顯示功能、系統模式切換功能或執行工具應用程式功能等，本發明對此不限制。此外，特定手勢可包含數目為一種以上的手勢。舉例而言，當觸控操作被判斷為符合特定手勢中的第一手勢時，投影裝置120可執行第一投影控制功能。當觸控操作被判斷為符合特定手勢中的第二手勢時，投影裝置120可執行相異於第一投影控制功能的第二投影控制功能。In the embodiment of the present invention, in step S204, in response to the touch operation conforming to the specific gesture, the projection device 120 executes the projection control function corresponding to the specific gesture. In other words, the user can control the projection device 120 to perform the corresponding projection control function through a specific gesture. In the embodiment of the present invention, the projection control function corresponding to a specific gesture includes, for example, a screen capture function, a control menu display function, a system mode switching function, or a tool application execution function, which is not limited by the present invention. In addition, the specific gesture may include more than one gesture. For example, when the touch operation is determined to conform to the first gesture in the specific gesture, the projection device 120 can perform the first projection control function. When the touch operation is determined to conform to the second gesture in the specific gesture, the projection device 120 can perform a second projection control function that is different from the first projection control function.

需特別說明的是，於本發明實施例中，投影裝置120可依據觸控操作是否符合特定手勢而決定是否執行投影控制功能。由於使用者可接觸觸控投影幕110的任何位置，以施予觸控操作，因此使用者無須移動位置來點擊觸控投影幕110上設置於固定位置的顯示物件來控制投影裝置120執行特定功能。本發明可大幅提昇使用者在使用觸控投影系統期間的操作便利性及流暢度。此外，在投影裝置120執行應用程式的期間，反應於觸控操作符合特定手勢，投影裝置120亦可執行額外的投影控制功能。換句話說，若投影裝置120判定觸控操作符合特定手勢，無論投影裝置120有無執行應用程式，投影裝置120皆可執行額外的投影控制功能。具體而言，當投影裝置120執行應用程式時，觸控投影幕110顯示的投影畫面PI為應用程式畫面。當觸控投影幕110偵測到觸控操作且投影裝置120判斷該觸控操作符合特定手勢，則投影裝置120可在顯示應用程式畫面的同時執行對應於該特定手勢的投影控制功能。It should be particularly noted that, in the embodiment of the present invention, the projection device 120 can determine whether to execute the projection control function according to whether the touch operation conforms to a specific gesture. Since the user can touch any position of the touch projection screen 110 to perform a touch operation, the user does not need to move the position to click a fixed position display object on the touch projection screen 110 to control the projection device 120 to perform a specific function . The present invention can greatly improve the operating convenience and fluency of the user during the use of the touch projection system. In addition, during the execution of the application program by the projection device 120, the projection device 120 can also perform additional projection control functions in response to the touch operation conforming to a specific gesture. In other words, if the projection device 120 determines that the touch operation conforms to a specific gesture, the projection device 120 can perform additional projection control functions regardless of whether the projection device 120 executes an application.
