Description

빛을 이용한 직접 포인팅시스템{A direct pointing system by use of light}A direct pointing system by use of light}

본 발명은 CRT, 액정패널, PDP등의 디스플레이를 갖는 텔레비젼(Television; TV)에 관한 것으로, 보다 상세하게는, 빛을 이용한 직접 포인팅에 의해 원하는 화면상의 메뉴를 쉽게 조작하여 선택할 수 있도록 한 빛을 이용한 직접 포인팅시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television having a display such as a CRT, a liquid crystal panel, and a PDP. More particularly, the present invention relates to a light that allows easy manipulation of a desired on-screen menu by direct pointing using light. It relates to a direct pointing system used.

일반적으로 TV셋트의 조작용으로 셋트상에 부착된 키패드 이외에 사용자가 원격 조작할 수 있는 리모콘이 있다. 이는 송신기와 수신기로 구성되며, 사용자가 송신기(transmitter)에 부착된 키패드상의 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, in addition to the keypad attached to the set for the operation of the TV set, there is a remote control that the user can remotely operate. It consists of a transmitter and a receiver, and when a user presses a button of a desired operation among a plurality of operation buttons on a keypad attached to a transmitter, a corresponding light signal IR is transmitted, and a receiver located on a set ) Receives the light signal of the transmitter and converts it into an electrical signal and transmits 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.

한편, 디지탈 다채널 방송에서는 프로그램으로 수십∼수백개의 채널이 제공되므로 시청자의 선택의 여지가 많아지는 동시에 프로그램 선택이 더없이 복잡해진다. 그래서, 데이타서비스의 하나로서 프로그램표나 각 프로그램의 내용에 관한 정보등을 제공하는 전자프로그램가이드(electronic program guide; EPG)가 기본적인 서비스의 하나로 상정되고 있다. 아울러, 현재 방영되는 프로그램내의 인물이나 지역등을 클릭하면, 그에 대한 이력이나 상세정보등을 제공하는 서비스도 제시되고 있다.On the other hand, in digital multi-channel broadcasting, since dozens to hundreds of channels are provided as a program, the viewer has more choice and at the same time makes the program selection more complicated. Therefore, an electronic program guide (EPG) that provides a program table and information on the contents of each program as one of data services is assumed as one of the basic services. In addition, when a person or region in the currently aired program is clicked on, a service that provides a history or detailed information thereof is also presented.

그런데, 종래에는 리모콘으로 TV화면의 메뉴를 조작할 때 키패드(Key-pad)나 I-포인터를 사용하여 TV의 커서를 일일이 조작하여 원하는 메뉴를 선택했다. 이로 인하여, 원하는 메뉴를 선택하기 위한 조작이 복잡하여 불편할 뿐 아니라 가리키고자 하는 목적물이 움직이고 있는 경우에는 더욱 힘들었다.However, in the related art, when a menu of a TV screen is operated with a remote controller, a desired menu is selected by manipulating the cursor of the TV by using a keypad or an I-pointer. As a result, the operation for selecting a desired menu is complicated and inconvenient as well as more difficult when the object to be pointed is moving.

따라서, 본 발명의 목적은 전술한 점을 감안하여 사용자가 일일이 리모콘을 조작하지 않고 빛을 이용하여 원하는 메뉴의 화면상의 위치를 직접 포인팅하여 간편하면서도 자유롭게 TV메뉴조작이나 움직이는 물체를 선택할 수 있는 빛을 이용한 직접 포인팅시스템을 제공함에 있다.Accordingly, an object of the present invention is to provide a light that allows the user to easily and freely select a TV menu operation or a moving object by directly pointing the position on the screen of the desired menu using light without operating the remote controller. It is to provide a direct pointing system using.

The system shown in FIG. 1 includes a pointer 10 capable of menu selection through a direct screen irradiation method. The pointer 10 is composed of a light emitting part 11 for emitting light of a laser light, a light emitting switch 12 for driving the light emitting part 11, and a selection switch 13 made of buttons for menu selection. . The system of FIG. 1 also includes a sensing unit 22 that attaches a sensing pad between the liquid crystal panel 21 and the backlight 23 to detect a position on the screen where light emitted from the pointer 10 is received, and a broadcast signal. It is provided with a main body 30 for performing the original function of the TV for receiving and viewing the display menu or broadcast content on the screen. The detailed structure of the main body 30 is shown in FIG.

And an image processing unit 33 for processing an image to be displayed on the screen under the control of the CPU 32. The main body unit 30 also includes a cursor generation unit 34 for generating a cursor to be displayed at a screen position corresponding to the position calculated by the position calculating unit 31 under the control of the CPU 32, and an image processing unit. And a display unit 35 for screen-displaying the image processed at 33 and the cursor generated at the cursor generation unit 34.

이러한 구성을 갖는 본 발명의 빛을 이용한 직접 포인팅시스템에 대한 동작을 도 3을 통해 구체적으로 설명한다.An operation of the direct pointing system using the light of the present invention having such a configuration will be described in detail with reference to FIG. 3.

본체부(30)는 화상처리부(33)에서 처리된 방송내용이나 메뉴를 디스플레이부 (35)를 통해 화면상에 디스플레이한다. 사용자는 디스플레이된 메뉴화면을 보고 포인터(10)의 발광부(11)를 원하는 화면상의 메뉴를 향하도록 하고 발광용스위치 (12)를 조작하여 레이저광등의 빛을 발광시킨다. 여기서, 액정패널(21)과 백라이트(23) 사이에는 빛을 감지할 수 있는 감지패드(sensing pad)가 부착되어 있다. 감지패드는 도 3에 보여진 바와 같이, 상·하(X축방향) 및 좌·우(Y축방향)로 일정간격씩 광센서소자들이 배열된 매트릭스형태의 구조를 갖는다. 액정패널(21) 화면의 소정위치에 빛이 도달하면, 감지패드로 된 감지부(22)가 이를 감지하여 감지신호를 본체부(30)의 위치계산부(31)로 출력한다. 위치계산부(31)는 감지부(22)의 감지신호로부터 위치를 계산하여 CPU(32)에 전달한다. 여기서, 위치계산하는 방법은 이미 공지된 내용이므로 구체적인 설명은 생략한다. CPU(32)는 계산된 위치데이타에 대응하는 화면상의 위치에 커서(cursor)가 표시되도록 커서생성부(34)를 제어한다. 커서생성부(34)는 CPU(32)의 제어하에 커서를 생성하여 디스플레이부(35)를 통해 해당 화면위치에 커서를 디스플레이시킨다. 사용자는 화면상의 현재 커서가 원하는 메뉴상에 위치하면, 포인터(10)의 선택스위치(13)를 조작하여 그 메뉴를 선택한다. CPU(32)는 포인터(10)에서 선택스위치(13)가 조작되면, 커서가 위치한 화면상의 메뉴를 사용자가 선택한 경우로 인식하여 해당 메뉴의 동작을 수행한다.The main body 30 displays the broadcast contents or menu processed by the image processing unit 33 on the screen via the display unit 35. The user looks at the displayed menu screen and directs the light emitting unit 11 of the pointer 10 to the desired menu on the screen, and operates the light emitting switch 12 to emit light of a laser lamp. Here, a sensing pad for sensing light is attached between the liquid crystal panel 21 and the backlight 23. As shown in FIG. 3, the sensing pad has a matrix-like structure in which the optical sensor elements are arranged at regular intervals in the up, down (X-axis direction) and left and right (Y-axis directions). When light reaches a predetermined position on the screen of the liquid crystal panel 21, the sensing unit 22, which is a sensing pad, senses this and outputs a sensing signal to the position calculating unit 31 of the main body unit 30. The position calculator 31 calculates a position from the detection signal of the detector 22 and transmits the position to the CPU 32. Here, since the method for calculating the position is already known, a detailed description thereof will be omitted. The CPU 32 controls the cursor generator 34 to display a cursor at a position on the screen corresponding to the calculated position data. The cursor generation unit 34 generates a cursor under the control of the CPU 32 and displays the cursor at a corresponding screen position through the display unit 35. When the current cursor on the screen is located on the desired menu, the user operates the selection switch 13 of the pointer 10 to select the menu. When the selection switch 13 is operated by the pointer 10, the CPU 32 recognizes that the user selects a menu on the screen where the cursor is located and performs an operation of the menu.

한편, 현재 커서가 화면상에 디스플레이된 피사체를 가리키고 있는 상태에서 사용자가 포인터(10)의 선택스위치(13)를 조작한 경우 CPU(32)는 그 피사체에 대한 위치를 표시한다. 즉, 도 3에 보여진 바와 같이 빛이 화면상의 (7,E)부분에 입사되어 커서가 위치한 경우, 그 위치를 표시한다.On the other hand, when the user operates the selection switch 13 of the pointer 10 while the cursor is pointing to the subject displayed on the screen, the CPU 32 displays the position of the subject. That is, as shown in FIG. 3, when the light is incident on the (7, E) portion of the screen and the cursor is positioned, the position thereof is displayed.

상술한 바와 같이, 본 발명의 빛을 이용한 직접 포인팅시스템은, 화면에 빛을 감지하는 패드를 부착하여 사용자가 리모콘을 일일이 조작하지 않더라도 원하는 메뉴 내지 피사체를 향하여 화면에 빛을 직접 조사시켜 빛이 조사된 화면상의 위치를 셋트내에서 인식하여 원하는 메뉴 선택을 할 수 있어 사용이 용이한 효과를 갖는다.As described above, the direct pointing system using the light of the present invention attaches a light sensing pad to a screen so that the light is irradiated by directly irradiating light onto a screen or a desired menu even if the user does not operate the remote controller. Recognized location on the screen can be selected within the set to the desired menu has an effect that is easy to use.
