The present invention relates to a control method of a wireless optical mouse that can be used while moving with a presenter.

In general, academic conferences, seminars, lectures, lectures, etc. are used for presentations (eg, Microsoft's application, PowerPoint).

In the presentation, the presenter connects the computer with the program for presentation and the projector which can display the contents displayed on the computer monitor on the screen, and then executes the presentation program on the computer. Will be

During the presentation, the presenter typically uses a laser pointer to indicate what is being displayed.

However, in order to move the page of the displayed content during the presentation process as described above, page up / down using a mouse mounted on the presentation computer or a remote controller provided by the projector, in addition to the laser pointer. Using the page up / down feature makes it difficult for the presenter to simultaneously operate the laser pointer and the computer mouse or projector's remote controller.

That is, in a normal presentation, the presenter displays a screen using a mouse connected to the presentation computer, and then directs the presenter's explanation with a laser pointer, and manipulates the mouse every time the contents are explained. There is a problem that the presentation does not proceed smoothly, such as a change.

Recently, a product equipped with a laser pointer on a wireless mouse using a Bluetooth communication method, RF, and IR has been introduced to solve this problem.

By the way, the wireless mouse equipped with the laser pointer has the advantage that it can be used at a certain distance from the presentation computer, but given that the movement of the wireless mouse is performed on a flat surface such as a desk, the presenter is also free to present. There is a limit to presenting on the move.

In order to overcome the limitation of the wireless mouse, the cursor may be moved by flipping the wireless mouse and using a finger or other object. In this case, the movement of the finger and the direction of the cursor are moved in opposite directions, thereby freely moving the cursor. Problems are difficult to make.

That is, a wireless mouse (in the case of an optical mouse) is composed of the principle of continuously photographing an image according to a movement, calculating a displacement value, and transmitting the calculated displacement value to a microcomputer of the computer main body.

On the contrary, when the wireless mouse is inverted about the X-axis or the Y-axis, and the finger is moved up and down by touching the mouse, the image captured by the mouse and the direction of movement of the finger are shifted in opposite directions. As a result, the cursor actually moves in the direction opposite to the direction in which the finger is moved.

This is because the relative speed of the stationary object relative to the moving object is shown in the opposite direction when the stationary object is seen from the moving object because the reflector, which is the source of the image, is not moving but the device for imaging the image is moving.

Therefore, when the user moves the cursor by using the wireless mouse, the inconvenience of having to present the presentation while moving the finger in the opposite direction to the movement of the cursor occurs.

The present invention has been made in view of the above problems, the control of the wireless optical mouse that can conveniently control the presentation computer while freely moving the wireless mouse using any one of the Bluetooth communication method or RF, IR. To provide a method.

Another object of the present invention is to provide a control method of a wireless optical mouse that enables a user to move the cursor in a desired direction and speed even when the wireless mouse is used upside down.

In order to achieve the above object effectively, the present invention provides a control method of a wireless optical mouse including a laser pointer, comprising: setting to a presentation mode; Inverting the mouse body in an axial direction to contact the subject with the imaging hole; The light of the light emitting means built in the mouse body hits the subject and is refracted and transmitted to the image sensor; Calculating the transmitted light as a displacement value in an image sensor; Recalculating a displacement value in the inverted axial direction among the calculated displacement values by multiplying a negative sign (−); And moving the mouse cursor in the same direction and speed as the movement of the subject based on the recalculated displacement value; Characterized in that it comprises a.

The displacement value in the axial direction is calculated so that the negative sign is multiplied by the mouse micom.

The displacement value in the axial direction is calculated so that the negative sign is multiplied in the receiver coupled to the computer body.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a system of a wireless optical mouse according to an embodiment of the present invention, Figure 2 is a flow chart showing a process of operating the wireless optical mouse according to the present invention.

As shown, the control method of the wireless optical mouse according to the embodiment of the present invention is possible by switching to the presentation mode installed in the mouse body 10.

The switching of the presentation mode is performed by changing the position of the mode conversion switch 12 provided on the side or the upper surface of the mouse. Here, the switching between the optical mouse mode and the presentation mode is not only a mode change switch but also a sensor for detecting a change in the amount of light recognized by various sensors, for example, the opening or closing of a notebook, or the like, by various sensors. It can also be realized through the back.

When the mode conversion switch 12 is operated, the computer microcomputer 30 recognizes the selected mode signal by transmitting the signal of the selected mode to the receiver 20 coupled to the computer main body according to the Bluetooth communication method.

When the user selects the presentation mode through the mode conversion switch 12, the optical mouse is held, the mouse is inverted with respect to the X axis or the Y axis, and the user's subject (finger) is moved to the imaging hole of the mouse (the hole for emitting light). ).

At this time, in the case of the conventional wireless mouse, the position of the transmitter that communicates with the computer main body is configured on the front side of the mouse (the part where the index finger and the middle finger of the user are placed). It is preferable to configure it to rotate as a reference.

After the user reverses the mouse body 10, the subject of the user is brought into contact with an imaging hole configured to capture the bottom surface.

In order for the optical mouse to perform a proper function, the subject in contact with the imaging hole should be made of a flat surface. However, since the shape of the subject is usually formed in a curved surface, when a part of the subject flows into the imaging hole, the object is installed inside the mouse. Since the distance between the optical system and the subject is not sufficiently secured, the imaging of the image sensor installed inside the mouse may not be properly performed.

To solve this problem, if a transparent cover is installed in the imaging hole so that a part of the subject does not flow into the imaging hole or a structure such as a protrusion is formed on the bottom of the mouse so that a gap is formed between the subject and the imaging hole, the above problem is solved. It can be supplemented.

When the light of the optical mouse hits the subject and is reflected and provided to the image sensor 14 through the improvement of the structure of the mouse, the image sensor 14 calculates the movement of the subject as the displacement value.

At this time, the image sensor 14 captures the movement of the subject thousands of times per second, and compares the captured values to output the displacement of the subject as a displacement value.

After the image sensor 14 outputs the displacement value, the displacement value is transmitted to the mouse microcomputer 16 installed in the mouse, and the mouse microcomputer 16 is one of the X and Y displacement values output from the image sensor 14. The negative displacement is multiplied by the negative sign (-).

After the negative sign is multiplied by the mouse micom 16, the mouse micom 16 transmits the displacement data to the microcomputer 30 of the computer main body through the transmitter.

Of course, the displacement data is transmitted to the receiver 20 and then the corresponding data is transmitted from the receiver 20 to the computer microcomputer 30 so that the cursor can be moved in the same direction as the movement of the subject.

In addition, after the cursor is moved through the presentation mode, a user may be required to click an icon to select an icon, and the click of the icon may be selected by pressing a button (not shown) separately installed on the wireless mouse. have.

In addition, the outer surface of the wireless mouse may be provided with a laser pointer 18 for use in the presentation mode. The laser pointer 18 may be implemented as a normal presenter in which a laser beam is emitted while the power is connected as the user presses.

Meanwhile, in the embodiment of the present invention, when the wireless mouse is in the presentation mode, the mouse micom 16 is set to multiply the negative sign with respect to the Y displacement value. However, the recalculation of the displacement value is not necessarily limited to that of the mouse microcomputer 16, and the receiver 20 may be configured to be recalculated in the same manner as the mouse microcomputer 16.

That is, when a program for recalculating the Y displacement value is installed in the receiver 20 and the data information outputted from the image sensor 14 is received by the Bluetooth communication method or the RF or IR communication method, the receiver 20 ) Is able to transmit data to the microcomputer 30 of the computer while recalculating the displacement value output from the image sensor 14.

Referring to the operation of the wireless optical mouse and a control method according to an embodiment of the present invention.

If the presentation is not in progress, the mode conversion switch 12 is operated to use the normal wireless mouse mode.

On the contrary, when the presentation is in progress, the mode conversion switch 12 is operated to switch to the presentation mode, and then the wireless mouse is inverted to contact the subject with the imaging hole.

At this time, when the direction of inverting the wireless mouse is rotated about the Y axis and the movement of the subject moves in the up and down direction, the movement of the subject is first calculated by the image sensor 14 as a displacement value and then moved to the mouse microcomputer 16. When transmitting, the mouse microcomputer 16 multiplies the Y displacement value among the received displacement value data by a negative sign.

Therefore, even if the movement of the subject moves in any of the up and down directions, as the displacement value is recalculated by the mouse microcomputer 16 and then transferred to the computer microcomputer 30, the cursor may move in the same direction and speed as the subject. Will be.

As described above, the present invention is a wireless optical mouse equipped with a function of a laser pointer and a wireless mouse at the same time, it is possible to conveniently control a presentation computer while freely moving using a Bluetooth communication method or a communication method such as RF or IR. There is.

In addition, even when the wireless mouse is used upside down, the user can move the cursor accurately in the direction and speed desired by the user, so that the presentation can be performed more efficiently.

Although the control method of the wireless mouse according to the embodiment of the present invention has been described above, the present invention is not limited thereto, and those skilled in the art can apply and modify the same.
