Description
本發明涉及一種光學觸控裝置，尤其是一種可實現多重感應的光學觸控裝置。 The invention relates to an optical touch device, in particular to an optical touch device capable of implementing multiple inductions.
隨著平面顯示時代的到來，諸如平面CRT顯示器、液晶、等離子顯示技術的不斷成熟和普及，基於紅外線掃描檢測原理為技術基礎的光學觸控交互技術優勢凸現，以此為依託市場優勢漸趨明顯。 With the advent of the era of flat display, such as the continuous maturity and popularization of flat CRT displays, liquid crystals, and plasma display technologies, the advantages of optical touch interaction technology based on the principle of infrared scanning detection are prominent, and it is becoming more and more obvious based on market advantages. .
目前，利用光學觸控技術的產品層出不窮，其主要分為兩類，一類是在觸控螢幕表面進行輸入的光學觸控產品，例如廣達的光學觸控LED螢幕，此類產品可以允許用戶用手指或者其他指示物在不觸碰螢幕表面的情況下進行輸入；另一類是不需要靠近顯示幕而通過遙控的方式進行輸入的產品，例如任天堂的Wii，可以透過移動和指向來與螢幕上的虛擬物件產生互動，例如，當用戶想要在遊戲中揮動球拍時，他只需要像現實中那樣直接揮動握有控制器的手臂就可以在遊戲中完成揮動球拍的動作。 At present, products using optical touch technology are endless, and they are mainly divided into two categories. One is optical touch products that are input on the touch screen surface, such as Quanta's optical touch LED screen, which allows users to use Fingers or other indicators are input without touching the surface of the screen; the other is a product that is input remotely without having to be close to the display screen, such as the Nintendo Wii, which can be moved and pointed to the screen. The virtual object creates an interaction. For example, when the user wants to swing the racket in the game, he only needs to directly swing the arm holding the controller as in reality to complete the swinging of the racket in the game.
然而，先前技術中的各類光學觸控產品都存在著各自的缺陷。當使用該允許用戶用手指或者其他指示物在不觸碰螢幕表面的情況下進行輸入的產品時，如果用戶距離螢幕較遠時就無法完成輸入；而使用該通過遙控的方式來輸入的產品時，在用戶沒有控制器 的情況下也無法進行輸入。 However, various types of optical touch products in the prior art have their own drawbacks. When using the product that allows the user to input with a finger or other indicator without touching the surface of the screen, if the user is far away from the screen, the input cannot be completed; and when the product is input by remote control, , the user does not have a controller In the case of this, it is not possible to input.
有鑒於此，有必要提供一種既能夠在螢幕表面進行輸入，又可以進行遙控輸入的光學觸控裝置。 In view of this, it is necessary to provide an optical touch device that can perform input on the screen surface as well as remote input.
一種光學觸控裝置，其包括：一個觸控面板；至少一個紅外光源，該紅外光源設置於該觸控面板的周邊，該紅外光源所發出的紅外光線將該觸控面板的表面所覆蓋；至少兩個線性感測器設置於該觸控面板的周邊，用來感測物體觸碰該觸控面板時反射的紅外光線；一個控制器，該控制器用來在該觸控面板上形成一紅外光點，並同時發出遙控訊號以對該觸控面板進行遙控輸入；一個與該觸控面板電連接的訊號接收裝置，用來接收該控制器的遙控訊號；至少兩個與該觸控面板電連接的紅外影像感測器，其圍繞該觸控面板設置，用來攝取該控制器投射到該觸控面板上的紅外光點圖像以確定其在該觸控面板上的位置及運動軌跡。 An optical touch device includes: a touch panel; at least one infrared light source, wherein the infrared light source is disposed at a periphery of the touch panel, and the infrared light emitted by the infrared light source covers the surface of the touch panel; Two line sensors are disposed at the periphery of the touch panel for sensing infrared light reflected by the object when the touch panel is touched; and a controller for forming an infrared light on the touch panel Pointing and simultaneously transmitting a remote control signal to remotely input the touch panel; a signal receiving device electrically connected to the touch panel for receiving a remote control signal of the controller; at least two electrically connected to the touch panel The infrared image sensor is disposed around the touch panel for capturing an infrared spot image projected by the controller onto the touch panel to determine its position and motion track on the touch panel.
與先前技術相比，本發明所提供的光學觸控裝置既能夠在螢幕表面進行輸入，又可以進行遙控輸入，大大的降低了對用戶輸入方式的限制，提高了用戶使用的靈活性。 Compared with the prior art, the optical touch device provided by the invention can input both on the screen surface and remote control input, which greatly reduces the limitation on the user input mode and improves the flexibility of the user.
