Abstract

PURPOSE: A remote pointing system is provided to select a menu a user wants by pointing the menu easily using a remote controller. CONSTITUTION: A remote pointing system consists of four parts. At first, a remote control sends a laser or an infrared rays signal crosswise toward the direction a user wants. At second, a sensing part senses the incident position of the signal, sent from the remote control, on a screen. At third, A MICOM controls the system so that the cursor can be located on the given position by calculating the position of the x-axis and the y-axis on the screen, and so that the given menu can be executed if the cursor is kept on a certain position for the stated time. At fourth, a display part shows the cursor under the control of the MICOM.

원격 포인팅시스템{A remote pointing system}Remote pointing system {A remote pointing system}

본 발명은 텔레비젼(Television; TV) 내지 컴퓨터(Computer) 등의 모니터를 갖는 디스플레이기기에 관한 것으로, 보다 상세하게는, 리모콘을 통한 원격 포인팅에 의해 원하는 화면상의 메뉴를 쉽게 선택할 수 있도록 한 원격 포인팅시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device having a monitor such as a television (Television) to a computer, and more particularly, a remote pointing system for easily selecting a desired on-screen menu by remote pointing through a remote controller. It is about.

일반적으로 TV셋트의 조작용으로 셋트상에 부착된 키메트릭스 이외에 사용자가 원격조작할 수 있는 리모콘이 있다. 이는 송신기와 수신기로 구성되며, 사용자가 송신기(transmitter)의 다수 동작버튼중 원하는 동작의 버튼을 누르면 그에 해당하는 빛의 신호(IR)가 전송되고, 셋트상에 위치하는 수신기(receiver)는 송신기의 빛신호를 받아서 전기적 신호로 변화시켜 셋트내의 제어부로 전송시킨다. 제어부는 수신받은 전기적 신호를 인식하여 그에 해당하는 동작이 이루어지도록 셋트내의 각 구성 동작을 제어한다.In general, there is a remote control that can be remotely operated by the user in addition to the key metrics attached to the set for the operation of the TV set. It consists of a transmitter and a receiver. When a user presses a button of a desired operation among a plurality of operation buttons of a transmitter, a signal IR corresponding to the light is transmitted, and a receiver located on the set receives a receiver of the transmitter. It receives the light signal, converts it into an electrical signal, and sends it to the control unit in the set. The control unit recognizes the received electrical signal and controls each configuration operation in the set to perform the corresponding operation.

이러한 리모콘은 화면상의 커서를 이동해가면서 원하는 메뉴를 선택하는 데, 이때 리모콘에서 커서를 이동시키기 위한 위치데이타가 발생한다. 리모콘에서 발생되는 위치데이타는 상대위치로, 셋트내의 제어부에서 다시 절대위치로 계산하여 그 위치로 커서를 이동시킨다.The remote controller selects a desired menu while moving the cursor on the screen, and location data for moving the cursor is generated. The position data generated by the remote controller is a relative position, and the control unit in the set calculates the absolute position again and moves the cursor to the position.

그런데, 위와 같이 종래에는 원하는 메뉴를 선택하기 위해 사용자가 일일이 리모콘을 조작하여 리모콘을 통해 위치데이타를 발생시켜야 하므로 불편함이 있다.However, in the related art, in order to select a desired menu, the user needs to generate location data through the remote controller by operating the remote controller one by one.

따라서, 본 발명의 목적은 전술한 점을 감안하여 사용자가 일일이 조작하여 위치데이타를 발생하지 않고 원하는 메뉴의 화면상의 위치를 리모콘을 통해 원격으로 포인팅하여 쉽게 선택할 수 있는 원격 포인팅시스템을 제공함에 있다.Accordingly, an object of the present invention is to provide a remote pointing system that can be easily selected by remotely pointing a location on a screen of a desired menu through a remote controller without generating location data by manipulating each one in view of the above-described point.

And a display for displaying a cursor on a screen according to the control of the microcomputer.

이하, 첨부한 도면들을 참조하여 본 발명의 바람직한 실시예를 상세히 기술하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 원격 포인팅시스템의 구성도를 나타낸다. 도 1에 나타낸 시스템은 원격조종을 통해 화면의 조작지령 메뉴 선택이 가능한 리모콘(11)을 구비한다. 도 1의 시스템은 또한, 세트의 화면 좌우측중 한측에, 그리고 상하측중 한측에 광센서(121,122)를 마련하여 리모콘(11)에서 발사된 레이저 또는 적외선이 수신되는 화면상의 위치를 감지하는 감지부(12), 감지부(12)의 감지신호로부터 위치를 계산하여 해당 화면위치에 커서(cursor)가 표시되도록 제어하는 마이콤(13), 및 마이콤(13)의 제어하에 화면상에 커서를 표시하는 표시부(14)를 구비한다. 이러한 구성을 갖는 도 1의 원격 포인팅시스템에 대한 동작을 도 2를 통해 구체적으로 설명한다.1 shows a configuration of a remote pointing system according to the present invention. The system shown in FIG. 1 includes a remote controller 11 capable of selecting an operation command menu of a screen through remote control. The system of FIG. 1 also includes a light sensor 121, 122 on one side of the left and right sides of the screen and one side of the top and bottom sides to detect a position on the screen where the laser or infrared light emitted from the remote controller 11 is received. (12), the microcomputer 13 for calculating a position from the detection signal of the detection unit 12 and controlling a cursor to be displayed at the corresponding screen position, and displaying the cursor on the screen under the control of the microcomputer 13; The display unit 14 is provided. An operation of the remote pointing system of FIG. 1 having such a configuration will be described in detail with reference to FIG. 2.

도 1에서, 사용자는 리모콘(11)을 원하는 화면상의 메뉴를 향하도록 하여 레이저 또는 적외선신호를 발사한다. 셋트의 화면은 도 2에 보여진 바와 같이 화면의 위쪽(X축방향)과 왼쪽(Y축)으로 일정간격씩 광센서소자들이 배열된 구조를 갖는다. 여기서, 리모콘(11)은 열십자형태(十)로 빛을 발산하여 배열되는 광센서소자의 수를 절감할 수 있도록 한다. 화면상의 소정위치에 빛이 도달하면, 광센서(121,122)가 이를 감지하여 X축과 Y축 각각의 물리적 위치데이타를 마이콤(13)에 전송한다. 마이콤(13)은 X축광센서(121)와 Y축광센서(122)로부터의 감지신호로부터 좌표를 계산하여 계산된 화면상의 좌표에 표시부(14)를 통해 커서를 표시한다. 여기서, 좌표계산하는 방법은 이미 공지된 내용이므로 구체적인 설명을 생략한다. 마이콤(13)은 표시된 커서위치가 일정시간 유지되면 그 위치의 메뉴가 선택된 경우로 인식하여 해당 메뉴의 동작을 수행한다. 만약, 사용자가 리모콘(11)의 위치를 변경하면, 그에 맞게 다시 위치를 계산하여 커서를 표시하도록 한다.In FIG. 1, the user fires a laser or infrared signal with the remote control 11 facing a desired on-screen menu. The screen of the set has a structure in which the optical sensor elements are arranged at regular intervals to the upper (X-axis direction) and the left (Y-axis) of the screen as shown in FIG. Here, the remote controller 11 can reduce the number of optical sensor elements arranged by dissipating light in a crisscross shape (十). When light reaches a predetermined position on the screen, the photosensors 121 and 122 detect this and transmit the physical position data of each of the X and Y axes to the microcomputer 13. The microcomputer 13 displays the cursor through the display unit 14 in the coordinates on the screen calculated by calculating coordinates from the detection signals from the X-axis light sensor 121 and the Y-axis light sensor 122. Here, the method of calculating the coordinates is already known, so a detailed description thereof will be omitted. If the displayed cursor position is maintained for a certain time, the microcomputer 13 recognizes that the menu of the position is selected and performs the operation of the menu. If the user changes the position of the remote controller 11, the position is calculated again accordingly to display the cursor.

상술한 바와 같이, 본 발명의 원격 포인팅시스템은, 화면에 광센서를 부착하여 사용자가 리모콘을 일일이 조작하여 위치데이타를 발생하지 않더라도 리모콘에서 송출되는 적외선 혹은 레이저신호가 수신되는 화면상의 위치를 셋트내에서 인식하여 원하는 메뉴 선택을 인식할 수 있어 사용이 용이한 효과를 갖는다.As described above, the remote pointing system of the present invention attaches an optical sensor to a screen so that the user can operate the remote controller to set the position on the screen where the infrared or laser signal transmitted from the remote controller is received even without generating position data. You can recognize the desired menu selection by recognizing it in the easy to use effect.
