Description

Pointing / Interface System {POINTING / INTERFACE SYSTEM}

The present invention relates to a pointing / interface system, and more particularly, to a pointing / interface system capable of simultaneously performing a function as a laser pointer and a mouse function among input devices for an information processing device such as a computer.

In various conferences and presentations, it is common for a presenter to perform a presentation by using an information processing device such as a computer, and to perform a presentation by displaying a large screen image on a screen using a beam projector. At this time, the presenter points to the image displayed on the screen using the laser pointer.

However, since the laser pointer has only a function of simply indicating a specific position on the screen, it is inconvenient to operate a mouse or a keyboard by going directly to the location where the computer is installed when the computer is to be operated during the presentation process.

In order to solve such inconvenience, a laser pointer is provided which provides a button for easily operating a computer in the laser pointer and wirelessly transmits a key signal according to the operation of the button to the computer. However, even in the case of a laser pointer provided with a button, the function of controlling the computer according to the operation of the button is extremely limited. For example, most laser pointers add only the functions of the Page Up and Page Down buttons on the keyboard.

In addition, although a wireless mouse has been proposed as a new input device of a computer, there are limitations in that a flat plate for manipulating a mouse such as a mouse pad is essential. In addition, new input devices using various types of sensors such as an acceleration sensor, a gyro sensor, and a touch sensor have been proposed, but an input capable of performing the same function as a conventional mouse without being restricted by a user's location. The situation is not practical to use the device.

However, the technique of tracking the coordinates on the screen of the pointing beam, including the technique disclosed in Korean Patent No. 0171847, is difficult to track the pointing beam because the pointing beam must be tracked within the image displayed on the screen.

That is, the pointing beam of a conventional laser pointer has a red beam shape having a wavelength in the range of 628 to 680 nm. If a portion of the laser beam that is close to or equal to the wavelength of the pointing beam exists in an image displayed on the screen, the pointing beam is difficult to track. In order to track this, there is a problem that the reliability is significantly lowered because it undergoes a complicated calculation process or an estimation process.

In addition, in order to overcome the difficulty of tracking as described above, the hardware itself is a high specification, which leads to an increase in the price of the product, such as a hardware-dependent system has a problem.

In the present invention, the VR pointing beam generator 11 emits a laser beam in the visible light region, for example, a red laser beam. In this case, when the VR pointing beam emitted from the VR pointing beam generator 11 touches the screen, a person may visually recognize it.

In addition, the irradiation direction of the VR pointing beam and the IVR pointing beam are adjusted so that they can enter together in a certain area when they touch the screen. That is, the emission direction of the VR pointing beam emitted from the VR pointing beam generator 11 corresponds to the emission direction of the IVR pointing beam emitted from the IVR pointing beam generator 12. For example, the irradiation direction of the VR pointing beam generator 11 and the IVR pointing beam generator 12 may be set to allow the VR pointing beam and the IVR pointing beam to enter within the size of a mask cursor on the screen.

Through the above configuration, the user recognizes the point displayed on the screen by the VR pointing beam as a cursor of a mouse, and manipulates the key signal input unit 13 provided in the pointing / input device 10 for VR pointing. The input signal for the coordinates indicated by the beam can be transmitted to the information processing device 30. At this time, the information processing device 30 recognizes the position on the screen of the VR pointing beam visually recognized by the user by tracking the position on the screen of the IVR pointing beam captured by the invisible light camera 40, and pointing. The key signal transmitted from the input device 10 can be recognized and processed as an input signal for the coordinates on the screen calculated by the IVR pointing beam.

In addition, the terminal controller 34 sequentially displays the correction points P1 to P8 in a predetermined order or displays them to be distinguished from other correction points P1 to P8, and the user displays the displayed or distinguished correction points P1. To P8), the VR pointing beam emitted from the pointing / input device 10 is irradiated. At this time, of course, the IVR pointing beam is also emitted.

Then, the terminal control unit 34 calculates the coordinates of the IVR pointing beam in the image captured by the invisible ray camera 40, thereby the coordinates of the correction points P1 to P8 and the IVR pointing beam in the image displayed by the terminal controller 34. The position of the screen, that is, the area A_1, is set in the image captured by the invisible light camera 40 using the coordinates calculated by tracking.

The position of the image output from the information processing device 30 in the captured image can be set.

Here, using the invisible light camera 40 as a camera capable of capturing visible light may reduce an error due to a difference in a photographing area between two cameras generated by using two cameras. To this end, the visible light blocking filter 41 of the invisible light camera 40 according to the present invention may be detachably provided from the invisible light camera 40. Then, the visible light cut filter 41 is taken from the invisible light camera 40 to take a correction image and transmit the corresponding image to the information processing device 30, the terminal control unit of the information processing device 30 It is possible to set the position of the image output from the information processing device 30 in the image captured by the invisible light camera 40 by tracking the positions of the correction points P1 to P8 from the image transmitted from 34.
