Such a pointing device may focus the public's attention to more effectively transmit information on the screen projected on the screen or allow the public to easily recognize information displayed on the screen of an image terminal such as a television or a monitor.

On the other hand, in the pointing device of the method of irradiating straight light, the point of indication is recognized by the public as the straight light irradiated onto the screen is reflected from the screen. Therefore, the point indicated by the pointing device is clearly visible on the dedicated projector screen, but if a diffuse reflection film is attached to the surface or is coated with an anti-reflective coating such as an LCD screen, the direct light is not reflected from the screen and the pointing device indicates. There was a problem that the point of doing was not clearly visible. Accordingly, a variety of pointing devices that can be used simultaneously on a projector dedicated screen and an LCD screen are being developed. However, a conventional pointing device has a switch that performs a function of outputting straight light and a function of generating an image pointer. A switch for performing a function and a switch for underlining text, moving an icon, a file, or dragging a screen are each independently provided, so that the configuration of the pointing device is complicated and operation is cumbersome.

Accordingly, there is a need for a pointing device that can be used simultaneously on a projector dedicated screen and an LCD screen and is easy to operate.

The pointing device 1 according to the present invention includes a housing 10, a power supply unit 20, a sensor unit 30, a first switch unit 40, a control unit 50, and a communication unit 60. Include.

The housing 10 is a main body of the pointing device 1 and is formed of a bar or rod-shaped member whose one side is elongated and can be held by a user. Since the housing 10 is formed of a bar or rod-shaped member, the pointing device 1 can be easily operated while the user is holding it with one hand. As shown in the figure, the side surface of the housing 10 that is in contact with the user when gripped is formed in a curved surface, so that a grip feeling and an aesthetic feeling can be improved at the same time. However, it is not limited to the shape of the housing 10 shown in FIGS. 1 and 2, and the housing 10 may be deformed into various shapes that the user can easily grip and manipulate. The housing 10 may have a space formed therein to accommodate the power supply unit 20.

The power supply unit 20 supplies power to the sensor unit 30, the first switch unit 40, the control unit 50, the communication unit 60, the laser output unit 70, and the second switch unit 80 to be described later. By supplying, it may be a conventional battery.

The sensor unit 30 senses the movement of the housing 10 to generate a position signal, and may be installed inside the housing 10. The sensor unit 30 receives power from the power supply unit 20 to generate a position signal corresponding to the movement of the housing 10, and may generate a position signal including an acceleration sensor and a gyro sensor. The sensor unit 30 transmits the generated position signal to the control unit 50.

The first switch unit 40 is an input means in the form of a button that is exposed to the outside of the housing 10 and can be located in the center of the upper surface of the housing 10 so that the user can easily operate it while holding the housing 10. have. However, the first switch unit 40 is not limited to being located in the center of the upper surface of the housing 10, and the position of the first switch unit 40 in the housing 10 may be variously modified. The first switch unit 40 is exposed to the outside of the housing 10 and is a touch pad unit 41 that recognizes a contact by a pressure type or a capacitive type, and the touch pad unit 41 is located under the touch pad unit 41. Including a press recognition unit 42 for recognizing a press of ), it is possible to recognize a user's touch state and simultaneously input a click signal. The push recognition unit 42 may be formed as a push button switch that moves downward when pressure is applied to the touch pad unit 41 to move current, and is restored when the pressure is released to block the current. . Therefore, as shown in (a) of FIG. 4, when the user touches the touch pad part 41 without pressing the touch pad 41, a touch signal is input, and as shown in FIG. 4(b), the touch pad When the press recognition unit 42 moves downward by pressing the unit 41, a click signal may be input.

The controller 50 receives a position signal from the sensor unit 30 and generates a position coordinate in the form of a plane coordinate. At this time, when a user's touch signal is input from the first switch unit 40, the control unit 50 transmits the position coordinates to the host device H connected to the display device D in real time, and the first switch unit ( When a touch signal is not input from 40), the controller 50 does not transmit the position coordinates to the host device H. The controller 50 may transmit the location coordinates to the host device H through the communication unit 60 that communicates with the host device H wirelessly or by wire. When a touch signal is input from the first switch unit 40 and the control unit 50 transmits the position coordinates to the host device H in real time, the host device H is a display device D as shown in FIG. An image pointer (I) is created in the display area (A) of ).

As described above, since the relative position coordinates are transmitted from the control unit 50 to the host device H in real time, the position of the image pointer I output on the display area A may be changed. By changing the position of the image pointer I, it is possible to easily indicate a specific position on the display area A. The image pointer I may be output as a shape of a specific shape, such as a circle, a ring, a square, a triangle, and an arrow, or as a picture in the form of a face such as a character or a logo, or as a continuously moving video. A display device with a diffuse reflection film attached to the surface, such as an LCD screen (D1) or an LCD television or computer monitor, or coated with an anti-reflective coating as the image pointer (I) is output as a picture or video in a specific shape or plane shape. Also in (D), the point indicated by the pointing device 1 can be clearly seen.

In addition, when a click signal is input from the first switch unit 40, the host device H draws an underline on the text along the image pointer I, or the icon touched by the image pointer I or You can move files or drag the screen. For example, as shown in FIG. 7, in a state in which the image pointer I is superimposed on the text displayed on the display area A, the pointing device 1 is pressed in the direction in which the text is extended. ), the host device H can underline the text along the image pointer I that moves in response to the movement of the pointing device 1. In addition, as shown in FIG. 8, when the pointing device 1 is moved while pressing the touch pad 41 while the image pointer I is superimposed on the icon or file displayed on the display area A, the host device In response to the movement of the pointing device 1, (H) may move the icon or file in the direction in which the image pointer I has moved.

In response to the movement of (1), the screen can be dragged in the direction in which the image pointer I has moved. As such, the pointing device 1 of the present invention can create an image pointer I with one first switch unit 40, underline text, move icons or files, or drag the screen, so that the pointing device ( The configuration of 1) is simpler and the operation can be made easier. In particular, a touch signal is input when the touch pad unit 41 of the first switch unit 40 is touched, and a click signal is input when the touch pad unit 41 is pressed, so that the user does not make the mistake of pressing the switch incorrectly. As a result, the lecture or presentation can proceed smoothly.

The laser output unit 70 receives power from the power supply unit 20 and outputs the laser light source R to the outside of the housing 10.

However, the second switch unit 80 is not limited to being positioned above the first switch unit 40, and the position and shape of the second switch unit 80 in the housing 10 may be variously modified. I can. The second switch unit 80 is a laser pointing mode in which the laser output unit 70 operates and the laser light source R is output, and the control unit 50 receives the touch signal and transmits the position coordinates to the host device H. The image pointing mode can be converted to each other. For example, when the second switch unit 80 is set to the laser pointing mode, the power supply unit 20 supplies power only to the laser output unit 70, and the control unit 50 provides the position coordinates to the host device (H). The transmission of is stopped, and the laser output unit 70 may output the laser light source R. Conversely, when the second switch unit 80 is set to the image pointing mode, the power supply unit 20 supplies power only to the control unit 50, and the laser output unit 70 limits the output of the laser light source R. , The control unit 50 may transmit the location coordinates to the host device H.

When the host device H is a desktop computer without a built-in wireless LAN, a receiver 90 that communicates with the communication unit 60 may be installed by implementing a local area network wirelessly. The receiver 90 is detachably coupled to the housing 10 to be mounted on the host device H if necessary, and the housing 10 is a recessed groove on the other side opposite to one side from which the laser light source R is output. 10a) is formed to accommodate at least a portion of the receiver 90. However, as shown in FIG. 2, it is not limited that the recessed groove 10a is formed on the lower surface of the housing 10, and the position of the recessed groove 10a may be variously modified. For example, the recessed groove 10a may be formed on the side of the housing 10.

In addition, the third switch unit 100 and the fourth switch unit 110 may be exposed outside the housing 10.

The fourth switch unit 110 is an input means in the form of a pressurized button, and may be used to convert the current screen of the display area A to the next screen. However, as shown, the second switch unit 80 and the third switch unit 100 are arranged parallel to the upper side of the first switch unit 40, and the fourth switch unit 110 is the first switch unit (40) It is not limited to being disposed on the lower side, and the positions and shapes of the third switch unit 100 and the fourth switch unit 110 in the housing 10 may be variously modified.

Meanwhile, the image pointer I may adjust at least one of shape, size, transparency, and color according to a control signal from the controller 50 or an input signal from the host device H. More specifically, when the host device H receives the position coordinates from the control unit 50 and outputs the image pointer I to the display area A of the display device D, the image on the display area A A selection screen in which at least one of the shape, size, transparency, and color of the pointer I can be adjusted may be activated. When the control signal of the controller 50 is input or the input signal of the host device H is input while the selection screen is activated, at least one of the shape, size, transparency, and color of the image pointer I is adjusted and reflected. I can. In this case, the control signal of the control unit 50 may be generated by the first switch unit 40, the third switch unit 100, or the fourth switch unit 110, or may be generated in response to the movement of the housing 10. In addition, the input signal of the host device H may be generated by manipulation of an input device connected to the host device H, for example, a mouse.

The sensor unit 30 installed in the housing 10 detects the movement of the housing 10 and generates a position signal (step (A)). The sensor unit 30 includes an acceleration sensor and a gyro sensor, and may receive power from the power supply unit 20 to generate a position signal corresponding to the movement of the housing 10. The position signal generated by the sensor unit 30 is transmitted to the control unit 50.

The controller 50 receives a position signal from the sensor unit 30 and generates a position coordinate in the form of a plane coordinate (step (B)). At this time, a laser pointing mode in which the laser output unit 70 outputs a laser light source R to the outside of the housing 10 by manipulating the second switch unit 80 exposed to the outside of the housing 10, and The controller 50 selects an image pointing mode in which a touch signal is received and the position coordinates are transmitted to the host device H (step (C-1)).

The touch signal may be input when only contact is made without pressing the touch pad part 41 of the first switch part 40.

The host device H receives the position coordinates and generates an image pointer I in the display area A of the display device D (step (D)). The image pointer I may be output as a shape of a specific shape, such as a circle, a ring, a square, a triangle, and an arrow, or as a picture in the form of a face such as a character or a logo, or as a continuously moving video. In this case, if necessary, at least one of the shape, size, transparency, and color of the image pointer I may be adjusted by manipulating the control unit 50 or the host device H. As the image pointer (I) is output as a picture or video in a specific shape or plane shape, the point indicated by the pointing device (1) also to the display device (D) with a diffuse reflection film attached to the surface or coated with an anti-reflection coating This can be clearly seen. In addition, since the position coordinates are transmitted to the host device (H) in real time from the control unit 50, the position of the image pointer (I) output to the display area (A) is changed to facilitate a specific position on the display area (A). I can instruct you to do.

On the other hand, when a click signal is input from the first switch unit 40, the host device (H) underlines the text along the image pointer (I) or moves the icon or file that the image pointer (I) is touching. Or drag the screen (step (E)). The click signal may be input while being energized when the touch pad part 41 of the first switch part 40 is pressed and the push recognition part 42 moves downward. For example, if the pointing device 1 is moved in the direction in which the text is extended while pressing the first switch unit 40 while the image pointer I is superimposed on the text displayed on the display area A, the host device ( H) may underline the text along the image pointer I moving in response to the movement of the pointing device 1.
