Abstract

An electronic apparatus, a cursor position checking method and a recording medium are provided to easily check a position of a cursor on a screen by recognizing an operational action of shaking a pointing device right and left. A pointing device operates motion of a cursor displayed on a screen of a display unit. If a motion signal for the motion of the cursor is received from the pointing device, a pointing controller calculates motion speed of the pointing device(S10). If the calculated motion speed is faster than preset reference speed, the number of reversing a motion direction which is an X axis direction or an Y axis direction is counted(S11,S14). If the counted number is larger than preset number, the pointing controller changes shape of the cursor(S16,S17).

Description

ELECTRICAL APPARATUS, CURSOR POSITION IDENTIFICATION METHOD AND RECORDING MEDIUM

The present invention relates to an electronic device, a cursor position checking method, and a recording medium, and more particularly, when a user does not find a location of a cursor displayed on a screen while using the electronic device, the user can operate the cursor only by operating a pointing device such as a mouse. The present invention relates to an electronic device, a cursor position checking method, and a recording medium that can easily check a position.

Recently, due to the widespread use of personal computers (Personal computer), the use of computers in the home or work is already a generalized trend. In addition, in recent years, more and more users are building and using a dual monitor system (see FIG. 1) using two display units in one computer, and connecting two or more display units to a single computer main body. Some users say

As a computer input device, a mouse and a keyboard are widely used. Various types of input devices, such as a touch screen method, an input device for the visually impaired, and a foot mouse for a user who cannot use the hand, have been developed and released. .

Among the input devices of the computer, an input device represented by a mouse (hereinafter referred to as a 'pointing device') is used to manipulate the movement of a cursor displayed on the screen of the display unit. In today's computer environment, where Microsoft's Windows operating system is dominated by computer operating systems, the use of a pointing device to manipulate cursor movements, such as a mouse, is almost universal. It is spreading.

However, in the process of using a computer, when a pointing device such as a mouse is operated to click a specific button without using the cursor of the computer, it often occurs that the cursor displayed on the screen cannot be found.

In particular, when using a dual monitor system or three or more display units (hereinafter, referred to as 'multi-monitor systems'), the overall screen width of the display units constituting the multi-monitor system is considerably wider due to the large display unit. In many cases, it is not easy to find a cursor to move the cursor without using the cursor.

In order to compensate for this, a pointing device has been proposed in which a separate button is provided on a pointing device such as a mouse, and when the corresponding button is pressed, the size of the cursor increases to find the position of the cursor. However, in this case, there is a disadvantage in that a separate button has to purchase a pointing device, and thus, a pointing device such as a mouse used in the related art needs to be replaced only because the location of the cursor is difficult to check.

In addition, a technique for locating the cursor in a specific area, for example, a lower edge area of the screen, has been proposed in which the size of the cursor is increased so that the user can find the cursor using a pointing device such as a mouse. The disadvantage is that the position must be manipulated until it is located in a specific area.

Accordingly, the present invention has been made to solve the above problems, and focuses on a pattern in which a typical user moves a pointing device such as a mouse to find the position of the cursor, and recognizes the user's usage pattern as described above.

A positioning method and a recording medium are provided.

In particular, according to the present invention, when the position of the cursor is not found in a multi-monitor system using two or more displays, the position of the cursor can be more easily found by merely shaking the pointing device such as a mouse.

In addition, by providing the pointing control unit in the form of a device driver operating under the operating system, it is possible to check the cursor position according to the present invention by only installing the device driver without purchasing a separate pointing device.

Hereinafter, with reference to the accompanying drawings will be described embodiments of the present invention in more detail. Here, in describing the electronic device according to the present invention, a computer to which a dual monitor system using two display units as shown in FIG. 1 is applied will be described as an example.

The computer according to the present invention, as shown in FIGS. 1 and 2, includes a first display portion 11a and a second display portion 11b, a pointing device 16 and a pointing controller 19. In addition, the computer according to the present invention includes a CPU 10 (Central Processing Unit), a chipset 13, a main memory 14, a hard disk drive 17 and a graphics adapter 12 which are central processing units.

The main memory 14 operates as a main memory of a computer, and is provided in a form of random access memory (RAM), and temporarily stores data or programs necessary for operating an operating system or another application program. Chipset 13 relays data exchange between CPU 10 and other components of the computer.

The graphic adapter 12 processes image data so that an image generated according to the operation of the computer can be displayed on the screens of the first display unit 11a and the second display unit 11b. The dual monitor function is provided so that an image can be displayed on the screen of the unit 11a and the second display unit 11b.

The pointing device 16 operates as an input device for manipulating the movement of a cursor displayed on the screen of the first display unit 11a or the second display unit 11b. In the present invention, as an example, the pointing device 16 is provided in the form of a mouse as shown in FIG. 1. In addition, the pointing device 16 may be provided in the form of another type of device for manipulating the movement of the cursor displayed on the screen, such as a track ball or a foot mouse. Other types of devices for manipulating movement can of course also be applied to the pointing device 16 according to the invention.

The pointing control unit 19 recognizes when a motion signal according to the manipulation of the pointing device 16 is input, and transfers information on the motion signal to the operating system 18 (OS). At this time, the operating system 18 changes the position of the cursor displayed on the first display unit 11a and the second display unit 11b according to the motion signal from the pointing control unit 19. Here, the pointing control unit 19 according to the present invention may be provided in the form of a device driver for transmitting a signal corresponding to the movement signal from the pointing device 16 to the operating system 18.

Meanwhile, the pointing control unit 19 according to the present invention calculates the movement speed of the pointing device based on the movement signal when the movement signal for moving the cursor is received from the pointing device 16.

In addition, the pointing control unit 19 detects whether the moving direction in the X-axis direction or the Y-axis direction is reversed when the cursor moves according to the chopped signal when the calculated movement speed is greater than or equal to the preset reference speed. Here, the reference speed is preferably set to a speed faster than the speed at which the user normally operates the pointing device 16. For example, when the user wants to find the position of the cursor on the screen, the pointing device 16 such as a mouse is used. It may be set in consideration of the speed of movement when shaking from side to side. Through this, the case where the speed is higher than the normal operation speed of the pointing device 16 can be recognized as an operation for the user to find the position of the cursor.

Also, by detecting whether the direction of movement of the cursor is reversed in one of the X-axis direction and the Y-axis direction while the movement speed is greater than or equal to the reference speed, a pointing device 16 such as a mouse when the user wants to locate the cursor. You will notice the motion of shaking) to the left and right.

Here, the pointing control unit 19 counts the number of times the direction of movement is reversed, and displays on the screen of the first display unit 11a or the second display unit 11b when the counted number is equal to or greater than a preset reference number. The event signal for changing the shape of the cursor is transmitted to the operating system 18 to facilitate the location of the cursor. At this time, when the event signal is transmitted from the pointing device 16, the operating system 18 changes the shape of the cursor displayed on the screen to facilitate confirmation by the user. Through this, the user repeats the operation of repeatedly shaking the pointing device 16 such as a mouse in the left and right and / or the up and down directions to find the position of the cursor by counting the number of times the direction of movement of the cursor is reversed. In this case, the operating system 18 may change the shape of the cursor by increasing the size of the cursor displayed on the screen or displaying a movement in which the circular shape increases around the cursor.

3 is a diagram illustrating an example in which a cursor moves according to an operation of the pointing device 16. Referring to FIG. 3, the pointing control unit 19 checks whether the moving direction of the cursor is reversed based on the motion signal input from the pointing device 16.

Referring to FIG. 3A, it can be seen that the moving direction of the pointing device 16 proceeds to the upper right corner. In the movement from the recognized points (X1, Y1) to (X2, Y2) based on the motion signal, the polarity of the displacement difference for both points is greater than 0 in both X and Y axes as shown in Equation 1 below. .

[Equation 1]

X2-X1> 0, Y2-Y1> 0

In addition, the polarity of the displacement difference between the two points in the movement from the points (X2, Y2) to (X3, Y3) shown in FIG. 3A is X-axis and Y as shown in Equation 2 below. Both axes are greater than zero.

[Equation 2]

X3-X2> 0, Y3-Y2> 0

As shown in [Equation 1] and [Equation 2], since the polarity of the displacement difference between the points does not change in the movement of the pointing device 16 as shown in FIG. 3 (a), the pointing control unit 19 ) Determines that the movement direction of the cursor is not reversed.

On the other hand, referring to Figure 3 (b), it can be seen that the moving direction of the pointing device 16 is moved to the upper right side, the movement direction is changed to the upper left. At this time, in the movement from the recognized points (X4, Y4) to (X5, Y5) based on the motion signal, the polarity of the displacement difference for the two points is the same as in [Equation 3] below. Greater than zero

[Equation 3]

X5-X4> 0, Y5-Y4> 0

By the way, the polarity of the displacement difference between the two points in the movement from the points (X5, Y5) to (X6, Y6) shown in FIG. 3 (b) is as shown in Equation 4 below. It is smaller than zero and larger than zero for the Y axis.

[Equation 4]

X6-X5 <0, Y6-Y5> 0

As shown in [Equation 3] and [Equation 4], in the movement of the pointing device 16 as shown in (b) of FIG. 3, the polarity of the displacement difference between the points is changed with respect to the X axis. The pointing controller 19 determines that the movement direction of the cursor is reversed.

Through the above configuration, the user recognizes an operation pattern for locating a cursor displayed on the screen, that is, an operation pattern for shaking the pointing device 16 such as a mouse several times in left and right directions and / or in an up and down direction. By changing the shape of the cursor so as to easily check the position of the cursor displayed on, the user can easily find the position of the cursor.

In addition, even when the reference speed or the direction of movement is reversed in the normal use of the pointing device 16, unnecessary cursors are not recognized by setting the reference speed and the reference frequency so that they are not recognized as an operation for checking the position of the cursor. It is possible to prevent the shape change from occurring.

On the other hand, the pointing control unit 19 according to the present invention can provide a setting window for setting the reference speed and the reference frequency. That is, the pointing control unit 19 provides a setting window displayed on the screen so that the user can set the reference speed and the reference frequency, and the reference speed and the reference frequency in such a manner that the user inputs the reference speed and the reference frequency through the setting window. Can be set. Accordingly, when the user checks the position of the cursor, the user can directly determine and apply which information to move the pointing device 16 and how much to move left and right or up and down.

Meanwhile, reference numeral 15 of FIGS. 1 and 2 is a keyboard which is one of other input devices of a computer.

Hereinafter, a method for checking a cursor position according to the present invention will be described with reference to FIG. 4.

First, when a user manipulates the pointing device 16, a motion signal is input from the pointing device 16 and the pointing control unit 19 recognizes this. At this time, the pointing control unit 19 calculates the movement speed of the pointing device 16 based on the input motion signal (S10). Here, when the pointing control unit 19 receives the motion signal, the pointing control unit 19 transmits information about the motion signal to the operating system 18 so that the operating system 18 changes the position of the cursor displayed on the screen correspondingly. The process is carried out separately.

Then, the pointing control unit 19 calculates a displacement difference in the X-axis direction and the Y-axis direction when the cursor moves according to the motion signal when it is determined that the calculated movement speed is equal to or greater than the above-described reference speed (S11). (S13).

Then, the pointing control unit 19 detects whether the moving direction in at least one of the X-axis direction and the Y-axis direction is reversed using the calculated displacement difference (S14). At this time, the pointing control unit 19 increases the count when it is determined that the moving direction is reversed (S15), and performs steps S10, S11 and S13 when it is determined that the moving direction is not reversed.

On the other hand, when the count is increased (S15), the pointing control unit 19 determines whether the current count is greater than or equal to the preset reference count (S16), and when it is determined that the count is greater than or equal to the reference count, the event signal for changing the shape of the cursor. Generated and delivered to the operating system 18 (S17). At this time, the operating system 18 receives the event signal to change the shape of the cursor displayed on the screen (S18) so that the user can easily recognize.

On the other hand, if it is determined in step S16 that the current count is less than the reference frequency, the pointing control unit 19 performs steps S10, S11, S13, S14, and S15 again. On the other hand, if it is determined that the movement speed calculated in step S11 is less than the reference speed, the pointing control unit 19 initializes the count (S12).

In the above-described embodiment, the electronic device according to the present invention has been described as an example of a personal computer as illustrated in FIG. 1, but a cursor is displayed on the screen and another type of manipulation by the pointing device 16 is performed. Electronic devices, for example, portable terminals such as notebook computers and PDAs (Personal Digital Assistants) may also be included in the electronic devices according to the present invention.

In addition, in FIG. 1, a computer to which a dual monitor system is applied has been described as an example. However, the present invention may be applied to a computer using one display unit or three or more display units (multi-monitor system).

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided.
