Description

Wireless Mouse Device with Pointer {Wireless mouse using as a pointer}

The present invention relates to the field of mouse devices. More specifically, by adding a wireless mouse function to a pointer, a lecturer or a conference host can display contents of educational materials or conference materials that are displayed on the front screen by themselves without the help of a separate assistant. The present invention relates to a pointer-based wireless mouse device that allows a training or a meeting to be carried out while changing.

In general, when a company conducts training or a meeting, training materials or meeting materials, which are created using a presentation program such as PowerPoint, and then stored in a notebook computer, are connected to a projector connected to the notebook computer. Training or meetings with content on the front screen will enhance the effectiveness of training or meetings.

In the case of training or meeting by using a projector as described above, the instructor or the meeting presenter is displayed on the screen of the screen installed in front by using a pointer that emits a small circular red laser beam. The teaching or meeting will be carried out by pointing out any specific part of the course that requires emphasis or specific explanations during the training or meeting.

As shown in FIG. 1, the pointer includes a power supply unit 1 in which a battery is mounted, a switch 2 for allowing a user to supply and cut off the power of the battery, and the switch. When (2) is turned on, it consists of a laser part 3 which emits a laser beam when power is applied from the power source part 1 described above.

On the other hand, the educational materials or meeting materials displayed on the front screen through the projector need to continuously change the contents by operating the laptop computer during the training or meeting, and the instructor or the meeting host is responsible for the training or meeting. While there is a lot of inconvenience in changing the contents of educational materials and meeting materials by operating the laptop through input devices such as a mouse or keyboard, it is common to facilitate the progress of training or meetings. A separate assistant will change the contents of the training materials and meeting materials displayed on the screen.

Therefore, in the related art, in order to proceed with education or a meeting, a separate auxiliary manpower is required in addition to an instructor or a conference coordinator, so that a relatively large number of manpower is introduced in the education or meeting.

In addition, in the related art, when the communication between the instructor or the meeting facilitator and the additional assistants to assist them is not well performed, there is a problem that the education or the meeting is not performed smoothly, so that the effect as expected cannot be obtained. .

The purpose of the present invention is to solve such a conventional problem, and by adding a wireless mouse function to the pointer, the instructor or conference facilitator can keep up with the educational materials or conference materials that are displayed on the front screen alone without the help of a separate assistant. The present invention provides a pointer-based wireless mouse device that can be used for teaching or meeting while changing contents.

According to the above configuration, the operation of the pointer and wireless mouse device according to the embodiment of the present invention is as follows.

After the battery is installed in the power supply unit 4, when the user turns on the laser beam switch 51 of the switch unit 5, the control unit 9 operates the laser unit 6 to operate the laser beam from the laser unit 6. Is emitted, and when the user turns off the laser beam switch 51 of the switch unit 5, the controller 9 stops the operation of the laser unit 6 so that the laser beam is not emitted from the laser unit 6. do. The user can use the laser beam emitted from the laser unit 6 to point out a specific part of the contents displayed on the screen of the screen installed in front of the user, which requires emphasis or specific explanation during the training or meeting. Will proceed.

Irrespective of the operation of the laser beam, the control unit 9 operates the projection light driver 10 to emit light from the projection light 111 of the image generator 11.

The light emitted from the projection light 111 forms an image on the surface of the TFT sensor 13 via the transparent hemisphere 113 into which the liquid 112 enters, and this image is generated by the TFT sensor 13. It is detected and converted into an electrical signal. At this time, when the user changes the inclination degree of the hemisphere 113 by holding the pointer combined wireless mouse device in hand, the liquid 112 sealed in the hemisphere 113 is in the hemisphere 112. As it moves around, the image formed on the surface of the TFT sensor 13 also changes. As such, the liquid 112 is detected and converted by the TFT sensor 13 according to the degree of the liquid 112 being concentrated in the hemisphere 113. If the signal is different, the control unit 9 detects the degree of inclination of the hemisphere 113, that is, the inclination of the pointer-use wireless mouse device, and uses the value as a kind of position coordinate.

In this case, when coordinates on the Z-axis are added using a signal input from the semiconductor acceleration sensor 8, spatial coordinates can be generated.

The hemispheres 113 may draw or engrave a pattern on the surface. For example, it can be used by engraving or embossing or printing a grid pattern, and a sticker printed with a pattern pattern can be used. The material of the hemisphere 13 may be implemented in a transparent glass or plastic kind.

By the pattern pattern passing through the hemisphere 113 by the projection light 111 and projecting the image on the surface of the TFT sensor 13, this image is detected by the TFT sensor 13 and converted into an electrical signal.

The position coordinates are transmitted to the notebook computer (not shown) by the control unit 9 through the RF transmitter 17, the wireless LAN 18, the Bluetooth 19, or the like, and thus the computer projected on the front screen. The position of the mouse pointer (arrow) is changed on the screen.

Bluetooth is strictly defined as a technical specification for wireless connection within 10m to 100m between portable devices such as mobile phones and laptop computers, network access points, and other peripheral devices.

The user can change the position of the mouse pointer (arrow) appearing on the computer screen projected on the front screen by using the pointer and wireless mouse device, and the left key switch 52 of the switch section 5 as necessary. A click operation is performed using the right key switch 53, and a scroll operation is performed using the upwheel switch 54 and the downwheel switch 55 to use the pointer-use wireless mouse device as a mouse.

On the other hand, when the user physically separates the image generating unit 11 from the mounting position of the pointer-use wireless mouse device (see the dotted line in FIG. 2), a different image is formed on the surface of the TFT sensor 13. In this case, the controller 9 immediately switches to the fingerprint recognition mode, and operates the backlight driver 15 to emit light from the backlight 16. As such, the light emitted from the backlight 16 is directed toward the user's finger which is placed in place of the image generating unit 11 on the upper portion of the TFT sensor 16, and the TFT sensor 16 is connected to the above-described finger. The image of the fingerprint is converted into an electrical signal and output to the sensor output unit 16. As such, when the image of the fingerprint of the finger is amplified and input through the sensor output unit 14, the controller 9 analyzes the fingerprint of the finger so that the training data or the meeting data in the memory 7 are output only to the authorized user. A security function can be added to a wireless mouse with a pointer.

Then, the user can adjust the amount of light emitted from the projection light 111 or the backlight 16 using the control switch 56 of the switch unit 5, and adjust other functions.

As described in the above embodiment, the present invention provides a wireless mouse function to the pointer, while the instructor or the coordinator changes the contents of the training materials or the meeting materials that are displayed on the front screen alone without the help of a separate assistant. By allowing training or meetings to take place, it is effective to operate the training or meetings economically and efficiently.
