Description

1375898 六、發明說明： 【發明所屬之技術領域】 本發明大體上是關於一種追縱光指標器之技術。更具 體而δ，本發明是關於一種追縱光指標器位置以仿直 (emulate)遠端控制裝置之裝置及方法。 一 【先前技術】· 光指標器係為將光束投射至一表面區域上以強調—目 =of lnteres〇之裝置。在許多會將演說資料顯示於 J幕上的場合’’像是在會議、演講、研討會或其他場人 二標器已成為普遍使用之工具。一般演說資料係： 用一連接至電腦的投影裝置，如一液晶投影機， 影至顯示榮幕上。在演說的過程中，演說者可在任何時亥^ =-先指標器產生一觀眾可看見的光點，以將觀眾的注 思力拉到顯示勞幕上之特定位置或目標物。 最常見的光指標器為手持式的筆型裝置，其具有電池 組、控制迴路、光源模組及透鏡組。此光源模組包含—光 ^譬如雷射光源或發光二極體（Light Emiuing Di〇de，l 之ίΪ長用以發出給定的光波長，如對應紅光、綠光或藍光 :指標器亦可含有開關或按鈕，用以啟動遠端控制之 Γ ^功能。例如’美國專利公開第2006/_7756號揭 不一種光指標器裝置，其上裝有開關 腦鍵盤之指令及/戍像是、、晋气邮動谷禋電 夂次像疋π鼠、觸控板及軌跡球等指標裝置 未，譬如選擇、移動、點擊左鍵、點擊右鍵及雙擊按 Γ1375898 鍵等。此光指標器發出-光束至被投射在顯示影幕上的声 像來產生-可見光點重疊在影像上。此光點係作為演說電 腦之控制游標。在影像處理器令具有一攝影機連接至演說 電腦用來掃描投影在螢幕上的影像。此影像處理器接著分 析此被掃描影像’以確認光指標器所發送之控制游標位 置，即光點之位置。使用者可導引此控制游標至營幕中一 位置並藉由開關來仿真（emulate)位置相關 (position-dependent)之電腦指令。 光指標器亦可含有控制器及無線模組來發送控制㈣ 至^說電腦。例如，美國專利公開第屬/〇2271〇7號揭露 了一種光指才票器’纟具有無線操作模組來發送控制訊號至 一演說電腦，此動作即代表壓下光指標器上給定之開關°。 其-開關可能是用來發送「上一頁」訊號給電腦，而另一 •開關可能是用來發送「下一頁」訊號給電腦。「上一頁」及 「下一頁」訊號將指示電腦顯示新的演說頁面並將之投影 φ 至螢幕上。 如 光指標器亦可與其他裝置整合。如美國專利公告第 Μ17,840號所揭示’一光指標^可整合至無線滑鼠中:此 整合之裝置可選擇性地當作滑鼠使用以與電腦進行控制訊 说溝通’以及當作光指標器使用以發送光束至投影勞幕上。 卜亦了改良光指標以產生模組化之輸出a 1 來作為投影系統之…號。美國專利出二;) 20二/:60號揭示了一種光指標器其具有一模組化輸 (早兀）被用來提供指令至投影系統。此投影系統具有一 4 1375898 整合：影像感測器來偵測其光指標器發送之光點位置。苴 :射’使用者可按壓光指標器上之按紐使其發出特定頻 率之脈波。此脈波指示投影系統監控其光指標器之位置作 為=「拖戈」之結果’直到使用者再次按壓按鍵停止此 脈波為止。 故些現有的光指標器使用機械按钮或開關，故僅可作 為遠端控制器來使用。使用者必須手動操控這些開關以控 制演說電腦。如此不僅麻煩，在實用上亦有困難，因為使 籲用者除了進行演說外，還須分散注意力去操控這些開關。 於整場演說期間，這些開關亦易發生錯誤或失效。 口此σ人希望^供一種能夠仿真遠端控制裝置（像是 無線滑鼠）之光指標器裝置，且不需使用手動開關。具體而 言，吾人希望提供一種光指標器裝置及方法，其可用於追 蹤光^曰“器之位置’並利用此位置來控制演說電腦。 - 【發明内容】 • 本發明揭露一種光指標器裝置，其包含一光源模組用 以將一光束投射至一表面上；一影像感測器模組，用以偵 測此投射光束打在表面上所產生可見光點之位置；及一發 送器’用以將此可見光點之位置發送至一遠端裝置，進而 對此裝置進行遠端控制。 本發明之一實施例包含了 一影像感測器裝置，其用於 一光指標器中將光束投射至一表面上；一影像感測器模 組’用以伯測此投射光束打在表面上所產生可見光點之位 置；及一發送器模組’用以將此可見光點之位置發送至一 1375898 遠端裝置。 本發明之另一實施例包含一方法，其係藉由一光指標 器仿真一遠端控制裝置。於此實施例中，一光指標器投射 一光束至一表面上以在此表面上產生一可見光點。並藉由 一整合至此光指標器中之影像感測器偵測此表面上對應此 可見光點之位置。此可見光點之位置會被發送至一遠端裝 置’則可根據此光束之投射位置對此遠端裝置進行控制。 【實施方式】 • 本發明提出一種光指標器裝置。此處所稱之光指標器 如同一般所使用者，係為一種將光束投射至一表面區域上 以強調一目標物之裝置。此表面區域可為一顯示螢幕，藉 由一與電腦連接之投影機產生影像，並將此影像投影至此 表面區域上。此光束可投射在顯示螢幕上成為一可見光點 與影像重疊。此光指標器包含一光源模組以發送此光束。 此光指標器亦包含一影像感測器模組，且此模組具有 φ 衫像感測器及一處理器。如此處常使用者，影像感測器 可為具有像素陣列之裝置或迴路以榻取並將光學影像處理 成電子訊號。此電子訊號可被一處理器處理以判定此光指 標器發出之可見光點所對應之位置。 • 根據本發明實施例所建構之一光指標器裝置係描繪於 圖中。光才曰払器1 〇〇具有一光源模組1 〇5，一影像感測 器模組u〇及-發送器模組115。光源模組1〇5:= 源s如雷射光源或發光二極體（Light Emitting 心，led) 光源，用於發出特定波長之光束，譬如對應紅光、綠光或 6 1375898 光之波長。此光束可被投射至一表面，譬如表面12〇, 二於此表面120上產生一可見光點125。此可見光點125 β .·.、員示成不同的圖形或形狀，譬如圓形區塊蝴蝶形狀、 游標形狀諸如此類等。 當光指標器100面向表面120並投射光束至其上時， 光線從表面120反射。此反射光會被位於光指標器}⑻中 的办像感測器模組11 〇所感測，其係用以擷取在光線的相 φ同方向上的影像。影像感測器模組110感測表面120及其 上之可見光點，並偵測光點之位置。經由自動偵測或對獲 得之影像進行處理及分析，可得知光點125位置。 接著，光點位置125可藉由發送器模組丨丨5發送至遠

(calibration routine) ’以照比例調整表面12〇上的位置，: 配合顯示於表面12〇上影像的位置。例如，光點125可2 定位重疊於一影像區域，以指示電腦13〇顯示新的演說影 像或幻燈片，譬如影像上的一圖像可代表演說内容之一= 像或頁數。此光點125在表面120上之位置係由表面12ζ 尺度之二維座標所決定。於接收到光點丨25的位置時，遠 φ端裝置130會將接收之位置映射（map)為表面12〇上所顯示 影像尺度之二維座標。 應瞭解遠端電腦130可具有從顯示螢幕至演說影像之 預定映射（mapping)。也應瞭解遠端電腦no可藉由投射影 像至顯示螢幕決定其映射關係。 或者’光指標器100亦可連續地移動穿過顯示螢幕12〇 以指示電腦130顯示新的影像或投影片。將光點125定位 在圖像上，或連續移動光指標器100等動作都具有和點擊 滑鼠按鍵一樣的效果，使電腦130跳至下一張幻燈片。在 8 U75898 此實施範例中，光指標器100可有效地 操作電腦130。 …、線α取來 在f -個實施範例中’遠端裝置13〇可為—玩具或遊 戲。可藉由光指標器100根據所需指令 此先指標器100可用來引導此遙控汽車至—特定位置。各 發送模組m將光點位置125發送至此遙控汽車時，此^ 控汽車被引導而移動至一特定位置。

Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention generally relates to a technique for tracking light indicators. More particularly, the present invention relates to an apparatus and method for tracking the position of a light director to emulate a remote control device. A [Prior Art] The light indexer is a device that projects a light beam onto a surface area to emphasize -mesh =of lnteres. In many occasions where the presentation materials are displayed on the screen of J, it seems to be a common tool in conferences, lectures, seminars or other venues. General speech data: Use a projection device connected to a computer, such as a liquid crystal projector, to display the screen. In the course of the speech, the presenter can generate a spot visible to the viewer at any time. The first indicator can be used to draw the viewer's attention to a specific position or object on the screen. The most common light indicator is a hand-held pen type device having a battery pack, a control loop, a light source module, and a lens assembly. The light source module includes a light source such as a laser light source or a light emitting diode (Light Emiuing Di〇de, which is used to emit a given wavelength of light, such as corresponding to red, green or blue light: the indicator is also It may include a switch or a button for initiating a remote control function. For example, 'US Patent Publication No. 2006/_7756 discloses a light indicator device having an instruction to switch a brain keyboard and/or an image. , Jinqi postal 禋 禋 禋 疋 疋 疋 鼠 鼠 mouse, touchpad and trackball and other indicators device, such as select, move, click the left button, right click and double-click Γ 589 589 589 589 589 589 589 Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ The light beam is generated by the sound image projected onto the display screen - the visible light point is superimposed on the image. This light spot serves as a control cursor for the speech computer. The image processor has a camera connected to the speech computer for scanning projection. The image on the screen. The image processor then analyzes the scanned image to confirm the position of the control cursor sent by the light indicator, that is, the position of the light spot. The user can guide the control cursor to a position in the camp. The position-dependent computer command is emulated by a switch. The light indicator can also include a controller and a wireless module to send control (4) to the computer. For example, US Patent Publication No. 2/2271 〇7 discloses a light-pointing device that has a wireless operation module to send a control signal to a speech computer, which represents the given switch on the light indicator. The switch may be used to send The "previous" signal is sent to the computer, and the other switch may be used to send the "next page" signal to the computer. The "previous page" and "next page" signals will instruct the computer to display the new speech page and The projection φ is on the screen. For example, the light indicator can be integrated with other devices. As disclosed in US Pat. No. 17,840, the 'one light indicator' can be integrated into the wireless mouse: the integrated device can be selectively Used as a mouse to communicate with the computer for control communication' and as a light indicator to send a beam of light onto the projection screen. Bu also improved the light indicator to produce a modular output a 1 as a projection system U.S. Patent No. ... of the two;) 20 b /: 60 discloses an optical pointing device having a modular transmission (early Wu) is used to provide instructions to the projection system. The projection system has a 4 1375898 integration: an image sensor to detect the position of the spot transmitted by its light indicator.苴 : Shooting user can press the button on the light indicator to emit a pulse wave of a specific frequency. This pulse indicates that the projection system monitors the position of its light indicator as a result of = "drag" until the user presses the button again to stop the pulse. Therefore, existing optical indicators use mechanical buttons or switches and can only be used as remote controllers. The user must manually manipulate these switches to control the speaking computer. This is not only troublesome, but also practically difficult, because the caller must distract attention to these switches in addition to the speech. These switches are also prone to errors or failures during the entire speech. This sigma hopes to provide a light indicator device that can simulate a remote control device (such as a wireless mouse) without the need for a manual switch. In particular, it is desirable to provide an optical indicator device and method that can be used to track the position of a light device and use this position to control a speech computer. - [Summary] The present invention discloses a light index device The method includes a light source module for projecting a light beam onto a surface; an image sensor module for detecting a position of the visible light spot generated by the projected light beam on the surface; and a transmitter The device is remotely controlled by transmitting the position of the visible spot to a remote device.
