本發明乃是關於一種互動式投影系統，特別是指一種透過輸入裝置上的色碼來界定輸入裝置之功能之互動式投影系統。The present invention relates to an interactive projection system, and more particularly to an interactive projection system that defines the functionality of an input device through color codes on an input device.
在現今資訊時代中，人類對於電子產品之依賴性與日俱增。筆記型電腦、行動電話、數位隨身聽、光學投影機等電子產品均已成為現代人生活及工作中不可或缺之應用工具。上述之電子產品均具有一輸入介面，用以輸入使用者所須指令，以使電子產品之內部系統自動執行此項指令。In today's information age, human dependence on electronic products is increasing. Electronic products such as notebook computers, mobile phones, digital walkmans, and optical projectors have become indispensable tools for modern people's lives and work. Each of the above electronic products has an input interface for inputting instructions required by the user so that the internal system of the electronic product automatically executes the command.
在科技越趨發達的現在，桌上型電腦以及筆記型電腦等之類的主機裝置皆已成為求學或工作中不可或缺的一部份。此外，由於簡報軟體的問世，使得許多人會將報告資料預先編輯好並儲存在主機裝置中，以在報告時將報告資料呈現於主機裝置的螢幕影像。為了使報告資料可以呈現於台下眾多聽眾面前，可以透過電性連接主機裝置的投影裝置，使得投影裝置可以在屏幕上投射影像，據以產生對應螢幕影像的投影畫面。如此一來，投影裝置除了可以使報告者有效且生動地將報告資料呈現給聽眾外，更加方便讓聽眾對報告資料進行提問與討論外。Nowadays, with the development of technology, host devices such as desktop computers and notebook computers have become an indispensable part of schooling or work. In addition, due to the advent of the presentation software, many people pre-edit the report data and store it in the host device to present the report data to the screen image of the host device at the time of the report. In order to enable the report data to be presented to a large number of listeners in the audience, the projection device can be electrically connected to the projection device of the host device, so that the projection device can project an image on the screen to generate a projection image corresponding to the screen image. In this way, in addition to enabling the reporter to effectively and vividly present the report data to the audience, the projection device is more convenient for the audience to ask questions and discuss the report data.
在先前技術下，雖然觸控板已漸行趨勢且朝多點觸控發展，但是多點時序處理，並沒有編號之分別，所以每一觸控點的權位都一樣。故，先前技術為了達到不同編號之光筆，通常要要在光 筆上發射出特定之訊息，如射頻、紅外線、或其它主動發射之電磁波。然而，這會導致較高的成本且在長時耗電下較容易使得電池壽命較差。In the prior art, although the touchpad has gradually evolved and developed toward multi-touch, the multi-point timing processing has no number difference, so the weight of each touch point is the same. Therefore, in order to achieve different numbers of light pens, the prior art usually needs to be in the light. The pen emits specific messages, such as radio frequency, infrared, or other electromagnetic waves that are actively emitted. However, this leads to higher costs and it is easier to make battery life worse under long-term power consumption.

請同時參照圖1與圖2，圖1為根據本發明例示性實施例所繪示之互動式投影系統之示意圖。圖2為根據本發明例示性實施例所繪示之互動式投影系統之區塊示意圖。互動式投影系統100包括M個輸入裝置110與投影裝置120，其中M為大於等於1之正整數並且圖1僅是示意實際操作的環境，本發明並不加以限定。每一輸入裝置110包括色碼與觸碰部114。投影裝置120包括投影模組122、第一影像擷取模組124、第二影像擷取模組126與處理模組127。觸碰部114鄰接於色碼之編碼區域112。投影模組122透過傳輸通道150連接至主機裝置130，進一步來說，主機裝置130透過傳輸通道150與投影裝置120進行資料傳輸，而使主機裝置130內所儲存的資料可以透過投影裝置120將主機裝置130的螢幕影像SI投射至屏幕140，據以產生對應的投影畫面。處理模組127連接第一影像擷取模組124及第二影像擷取模組126。一般來說，屏幕140通常設置在投影裝置120的投射孔前方，且背景通常為白色，以利投影裝置120進行投射而產生投影畫面。但是，由於屏幕140沒有實際的作動，而是僅為一種可被投射之平面，因此未繪示於圖2的功能方塊圖中，但並不代表此互動投影系統100不需要使用屏幕140。Please refer to FIG. 1 and FIG. 2 together. FIG. 1 is a schematic diagram of an interactive projection system according to an exemplary embodiment of the present invention. 2 is a block diagram of an interactive projection system in accordance with an illustrative embodiment of the invention. The interactive projection system 100 includes M input devices 110 and projection devices 120, where M is a positive integer greater than or equal to 1 and FIG. 1 is merely an illustration of an actual operating environment, which is not limited in the present invention. Each input device 110 includes a color code and a touch portion 114. The projection device 120 includes a projection module 122, a first image capturing module 124, a second image capturing module 126, and a processing module 127. The touch portion 114 is adjacent to the code region 112 of the color code. The projection module 122 is connected to the host device 130 through the transmission channel 150. Further, the host device 130 performs data transmission with the projection device 120 through the transmission channel 150, so that the data stored in the host device 130 can be hosted through the projection device 120. The screen image SI of the device 130 is projected onto the screen 140 to generate a corresponding projected picture. The processing module 127 is connected to the first image capturing module 124 and the second image capturing module 126. In general, the screen 140 is typically disposed in front of the projection aperture of the projection device 120, and the background is typically white to facilitate projection by the projection device 120 to produce a projected image. However, since the screen 140 has no actual action, but is only a plane that can be projected, it is not shown in the functional block diagram of FIG. 2, but it does not mean that the interactive projection system 100 does not need to use the screen 140.
在本實施例中，色碼(color code)為由顏色資料與位置資料所組成並且互動式投影系統100能夠透過色碼界定輸入裝置110之功能，其中顏色資料可以例如是紅色、黃色或綠色，但並不以列舉者為限。具體來說，在一實施例中，輸入裝置110之外型通常會設計為一筆型殼體以利使用者的操作使用，而本揭露內容透過將一色環(color ring)套裝在該輸入裝置110之編碼區域112，並且透過色環在編碼區域112的不同位置與色環本身的顏色來定義不同的色 碼(亦即進行編碼)，而且不同的色碼會界定輸入裝置110之不同功能，其色碼與輸入裝置110之功能的對應關係內建於查找表128。也就是說，在同一輸入裝置110下，如果改變其色碼(亦即改變顏色資料與位置資料其中至少之一)，則會將輸入裝置110之原本功能切換至另一特定功能。In this embodiment, the color code is composed of color data and location data, and the interactive projection system 100 can define the function of the input device 110 through the color code, wherein the color data can be, for example, red, yellow or green. However, it is not limited to the enumerators. Specifically, in an embodiment, the input device 110 is generally designed as a one-piece housing for user operation, and the present disclosure is applied to the input device 110 by a color ring. The coding region 112, and different colors are defined by the color ring at different positions of the coding region 112 and the color of the color circle itself. The code (i.e., encoded), and the different color codes define different functions of the input device 110, and the correspondence between the color code and the function of the input device 110 is built into the lookup table 128. That is to say, under the same input device 110, if the color code is changed (i.e., at least one of the color data and the location data is changed), the original function of the input device 110 is switched to another specific function.
此外，投影模組122透過傳輸通道150連接至主機裝置130以接收主機裝置130所傳送的螢幕影像SI，並且投影模組122將螢幕影像SI投射至一屏幕140以產生一投影畫面，其中傳輸通道150為一傳輸纜線或利用無線通訊協定之一無線傳輸通道。舉例來說，當投影裝置120與主機裝置130之間的信號連結方式為有線的電性連接時，投影裝置1200具有影像傳輸線(未繪示)，而主機裝置130具有對應此影像傳輸線的連接埠(port，未繪示)，其中連接埠例如是VGA連接埠或HDMI連接埠。透過上述影像傳輸線與連接埠之間的插接，主機裝置130能電性連接投影裝置120，從而能傳遞電信號至投影裝置120。當投影裝置120與主機裝置130之間的信號連結方式為無線連接時，投影裝置120與主機裝置130之間可以透過藍芽(bluetooth)或無線網路而建立無線連接。如此，投影裝置120能接收來自主機裝置130的無線信號而投影對應此無線信號的影像在屏幕140上，無線訊號可以是射頻(radio frequency，RF)的形式，其典型使用頻段範圍可分30KHz~300KHz的低頻頻段、300KHz~3MHz的中頻頻段以及3MHz~30MHz的高頻頻段。於所屬技術領域具通常知識者更可以視情況，而使用3KHz~30KHz的甚低頻頻段至30GHz~300GHz的極高頻頻段，故本發明在此不加以限制。In addition, the projection module 122 is connected to the host device 130 through the transmission channel 150 to receive the screen image SI transmitted by the host device 130, and the projection module 122 projects the screen image SI to a screen 140 to generate a projection image, wherein the transmission channel 150 is a transmission cable or wireless transmission channel using one of the wireless communication protocols. For example, when the signal connection mode between the projection device 120 and the host device 130 is a wired electrical connection, the projection device 1200 has an image transmission line (not shown), and the host device 130 has a connection corresponding to the image transmission line. (port, not shown), where the port is, for example, a VGA port or an HDMI port. The host device 130 can be electrically connected to the projection device 120 through the plug-in connection between the image transmission line and the connection port, so that the electrical signal can be transmitted to the projection device 120. When the signal connection mode between the projection device 120 and the host device 130 is wirelessly connected, a wireless connection can be established between the projection device 120 and the host device 130 via a Bluetooth or wireless network. In this manner, the projection device 120 can receive the wireless signal from the host device 130 and project the image corresponding to the wireless signal on the screen 140. The wireless signal can be in the form of radio frequency (RF), and the typical frequency range can be divided into 30KHz~ 300KHz low frequency band, 300KHz~3MHz IF band and 3MHz~30MHz high frequency band. Those skilled in the art can use the very low frequency band of 3 kHz to 30 kHz to the very high frequency band of 30 GHz to 300 GHz, as the case may be, and the present invention is not limited thereto.
一般來說，主機裝置130的螢幕影像SI可以透過電性連接主機裝置130的液晶顯示器(liquid crystal display，LCD)或陰極射線管(cathode ray tube，CRT)諸如此類之顯示裝置(未繪示於圖2)來進行呈現。另外，螢幕影像SI可以不需透過顯示裝置呈現，而是直接透過投影裝置10投射於屏幕12來進行呈現。舉例來說，當主機 裝置130為桌上型電腦時，操作者不一定要將桌上型電腦電性連接液晶顯示器，而是可以直接將桌上型電腦電性連接投影裝置120，即可順利進行桌上型電腦的操作，使得投影裝置120所產生的投影畫面亦等同於螢幕影像SI，因此本發明在此不加以限定是否需要使用顯示裝置。Generally, the screen image SI of the host device 130 can be electrically connected to a liquid crystal display (LCD) or a cathode ray tube (CRT) of the host device 130 (not shown in the figure). 2) to present. In addition, the screen image SI can be presented without being transmitted through the display device, but directly projected onto the screen 12 through the projection device 10. For example, when the host When the device 130 is a desktop computer, the operator does not have to electrically connect the desktop computer to the liquid crystal display, but can directly connect the desktop computer to the projection device 120 to perform the desktop computer smoothly. The operation is such that the projection screen generated by the projection device 120 is also equivalent to the screen image SI. Therefore, the present invention does not limit whether or not the display device is required.
第一及第二影像擷取模組124與126用以擷取輸入裝置110之影像。於實務上，第一及第二影像擷取模組124與126可以為一種由電荷耦合元件(charge coupled device，CCD)或是互補式金屬氧化物半導體(complementary metal oxide semiconductor，CMOS)所製成且可感測影像的元件，但本發明不以此為限。在一實施例中，輸入裝置110的觸碰部114為一發光部，並且發光部包括發光模組1141、電池單元1142與觸碰感應單元1143。發光模組1141用以發射可見光或不可見光(例如紅外線)，電池單元1142電性連接發光模組1141，電池單元1142用以提供發光模組1141工作時所需之電能BV。觸碰感應單元1143電性連接發光模組1141，觸碰感應單元1143用以判斷輸入裝置110是否觸碰到屏幕140，其中如果觸碰感應單元1143觸碰到屏幕140，則觸碰感應單元1143傳送發光訊號LS至發光模組1141以觸發發光模組1141進行發光。The first and second image capturing modules 124 and 126 are configured to capture an image of the input device 110. In practice, the first and second image capturing modules 124 and 126 may be made of a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). The components of the image can be sensed, but the invention is not limited thereto. In one embodiment, the touch portion 114 of the input device 110 is a light emitting portion, and the light emitting portion includes a light emitting module 1141, a battery unit 1142, and a touch sensing unit 1143. The light-emitting module 1141 is configured to emit visible light or invisible light (for example, infrared light), and the battery unit 1142 is electrically connected to the light-emitting module 1141. The battery unit 1142 is configured to provide the electric energy BV required for the operation of the light-emitting module 1141.

請同時參照圖3A與3B，圖3A與3B為根據本發明例示性實施例所繪示之辨識輸入裝置之功能之示意圖。當互動式投影系統100在校正模式(calibration mode)下，處理模組127會透過第一及第二影像擷取模組124與126以將輸入裝置110之觸碰部114定義為圓心，並據此來設定對應於位置資料之第一半徑r1與第二半徑r2，並且將觸碰部114所在之位置予以定位以進行座標校正，其中第二半徑r2大於第一半徑r1。接著，處理模組127會開始辨識輸入裝置110上的色碼。進一步來說，處理模組127會透過第一及第二影像擷取模組 124與126會依序在第一圈內(亦即第一半徑r1內)與第二圈內(亦即第二半徑r2減去第一半徑r1)尋找顏色資料(亦即對輸入裝置110之色碼之顏色資料進行色彩過濾判斷)，以將輸入裝置110之色碼與查找表128進行比較，並據此傳送功能辨識資料FD至主機裝置130，以決定輸入裝置110之功能。須注意的是，本揭露內容主要是以顏色資料與位置資料所形成的色碼來定義輸入裝置110之功能，因此並不以顏色之數量與位置資料之數量作為限制，並且所述第一圈為表示第一位置的位置資料，第二圈為表示第二位置之位置資料。據此，互動式投影系統100能夠以色碼的方式來區分不同的輸入裝置以降低成本並且符合人性化的使用，並且適用於多個輸入裝置同時使用，並無侷限輸入裝置之數量。Please refer to FIG. 3A and FIG. 3B simultaneously. FIGS. 3A and 3B are schematic diagrams showing the function of the identification input device according to an exemplary embodiment of the present invention. When the interactive projection system 100 is in the calibration mode, the processing module 127 passes the first and second image capturing modules 124 and 126 to define the touch portion 114 of the input device 110 as a center, and according to The first radius r1 and the second radius r2 corresponding to the position data are set, and the position of the touch portion 114 is positioned for coordinate correction, wherein the second radius r2 is greater than the first radius r1. Next, the processing module 127 will begin to recognize the color code on the input device 110. Further, the processing module 127 transmits the first and second image capturing modules. 124 and 126 will sequentially search for color data in the first circle (ie, within the first radius r1) and the second circle (ie, the second radius r2 minus the first radius r1) (ie, for the input device 110) The color code of the color code is subjected to color filter determination) to compare the color code of the input device 110 with the lookup table 128, and accordingly transmit the function identification data FD to the host device 130 to determine the function of the input device 110. It should be noted that the disclosure mainly defines the function of the input device 110 by the color code formed by the color data and the location data, and therefore is not limited by the number of colors and the number of location materials, and the first circle To indicate the location data of the first location, the second circle is the location data indicating the second location. Accordingly, the interactive projection system 100 is capable of distinguishing different input devices in a color code manner to reduce cost and conform to humanized use, and is suitable for simultaneous use of a plurality of input devices without limiting the number of input devices.
當互動式投影系統100進入正常模式時，本實施例能夠透過投影裝置120將輸入裝置110在投影畫面之移動軌跡對應地顯示於螢幕影像。舉例來說，當輸入裝置110之色碼為定義為紅色書寫筆時，則使用者利用輸入裝置110在屏幕140上之移動軌跡，會呈現出紅色的移動軌跡。同理，當輸入裝置110之色碼為定義為黃色書寫筆時，則使用者利用輸入裝置110在屏幕140上之移動軌跡，會呈現出黃色的移動軌跡。When the interactive projection system 100 enters the normal mode, the present embodiment can display the movement trajectory of the input device 110 on the projection screen correspondingly to the screen image through the projection device 120. For example, when the color code of the input device 110 is defined as a red writing pen, the user may display a red moving track by using the movement track of the input device 110 on the screen 140. Similarly, when the color code of the input device 110 is defined as a yellow writing pen, the user can display a yellow moving track by using the movement track of the input device 110 on the screen 140.
值得一提的是，查找表128為配置於儲存單元，並且在本實施例中，查找表128定義為色碼與輸入裝置110之功能的對應關係，其中儲存單元為光罩唯讀記憶體(Mask ROM)、可抹除式唯讀記憶體(EPROM)、電氣式可抹除唯讀記憶體(EEPROM)或快閃記憶體(Flash Memory)。It is worth mentioning that the lookup table 128 is configured in the storage unit, and in the embodiment, the lookup table 128 is defined as a correspondence between the color code and the function of the input device 110, wherein the storage unit is a mask read-only memory ( Mask ROM), erasable read-only memory (EPROM), electrical erasable read-only memory (EEPROM) or flash memory.
