Description

How to display the mouse cursor {method of displaying mouse cursor}

The present invention relates to a method of displaying a mouse cursor on an output device (monitor) of an IT information device, and more particularly, to prevent personal information input through a virtual keypad from being leaked to the outside by screen hacking or peeking. It relates to a mouse cursor display method for.

In the modern information society, there are many IT information devices of various forms (for example, personal computers, mobile phones, smart phones, tablet computers, financial automated terminals, automatic ticket issuing machines, access control systems, etc.). Most of these information devices have to receive a variety of information from the user, a recent trend is the use of a virtual keypad (virtual keyboard) that is graphically displayed on the screen screen as an input means.

In a typical example, when an online banking using a computer requires a user to enter important personal information such as an account number, password, or security card number, a virtual keypad is displayed on a monitor screen of an IT information device. Even when online banking using a smart phone, a virtual keypad is displayed on the smart phone's touch screen to input passwords. This virtual keypad comprises a plurality of virtual keys arranged with symbols (numbers or letters or special characters). The user may input the personal information such as an account number, password or security card number even if the user does not input a key by sequentially selecting the virtual keys of the virtual keypad by dragging or touching the pointing means or the like. Methods of sequentially selecting virtual keys of the virtual keypad include a method of clicking a mouse cursor at a position of the virtual key, directly touching the virtual keys one by one, and dragging while touching the virtual keys to be selected.

IT information devices may be composed of an input device and an output device separately, or an input device and an output device may be integrated. For example, a general personal computer is composed of a keyboard device and an mouse device as input devices and a monitor as output devices. However, a smart phone, a financial automated terminal, an automatic ticket issuing machine, etc. are configured as a touch screen, and an input device for inputting information by a user and an output device for outputting a screen are integrated.

Typically pointing devices that can be used in IT information devices include mouse devices, trackballs, touch pads, tablets, joysticks, pointing sticks, fingers, and the like.

A conventional virtual keypad currently used is arranged in a position where a plurality of symbols are fixed, and when a user presses any virtual key, symbol information corresponding to the pressed virtual key is stored. Since a conventional virtual keypad is arranged in a fixed position, a user may input information by hacking the touch position from the outside. In addition, when a user clicks or touches an arbitrary virtual key of the virtual keypad by using a pointing means or the like, both the symbols arranged on the virtual keys of the virtual keypad and the position of the mouse cursor are displayed on the screen. There is a risk of personal information entered by the user through hacking or shoulder sniffing. Since the external leakage of important information input to the virtual keypad may cause serious economic loss to the user, a technique for protecting the information input to the virtual keypad needs to be developed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to select a real virtual cursor and a virtual mouse cursor on a screen when a user selects an arbitrary virtual key of a virtual keypad by using a pointing means. By displaying at the same time, it is to provide a mouse cursor display method that can protect the information input by the user.

According to an aspect of the present invention, there is provided a mouse cursor display method comprising: a first step of a control unit outputting an actual mouse cursor and a virtual mouse cursor on a screen;

When the pointing means moves, the control unit calculates the actual mouse cursor coordinates according to the movement path of the pointing means, displays the actual mouse cursor on the actual mouse cursor coordinates, and sets the virtual mouse cursor coordinates different from the movement path of the pointing means. Calculating and displaying the virtual mouse cursor in the virtual mouse cursor coordinates;

And a third step of the controller selecting and inputting a virtual key corresponding to the position of the actual mouse cursor.

As described above, according to the present invention, since the actual mouse cursor and the virtual mouse cursor are simultaneously displayed on the virtual keypad screen, even if a third party hacks or peeks the user's input information, the user's input cannot be accurately recognized. There is an advantage to protecting information.

Hereinafter, a mouse cursor display method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic configuration diagram of an information apparatus to which the present invention is applied.

An information apparatus to which the present invention is applied includes a monitor 11 displaying a virtual keypad and a mouse cursor image on a screen, a pointing means 12 for receiving a user's operation, and a monitor 11 for receiving input from the pointing means 12. A control unit 13 for output control of the virtual keypad and the mouse cursor image, and a storage unit 14 storing the program for performing the virtual keypad display method according to the present invention and providing the program to the control unit 13.

Here, the monitor 11 may be implemented as a touch screen capable of both input and output, and the pointing means 12 may be implemented as a mouse device, a trackball, a touch pad, a tablet, a joystick, a pointing stick, a finger, and the like. .

In general, a virtual keypad is composed of a plurality of virtual keys, and one symbol (a number from 0 to 9, alphabet letters from a to z, or a special character) is displayed in correspondence with one virtual key. Of course, the virtual keys constituting the virtual keypad may include a virtual key without a symbol, or a symbol may not be displayed on all the virtual keys.

The control unit 13 according to the present invention displays a real mouse cursor and a virtual mouse cursor on the monitor 11 at the same time, the symbol corresponding to the virtual key where the actual mouse cursor is located when the user selects any virtual key (click or touch) Is recognized as a user-selected symbol. That is, when the user selects a random virtual key, it can be seen that the actual mouse cursor and the virtual mouse cursor are located at different positions so that two or more different virtual keys are selected. However, the control unit 13 according to the present invention recognizes that the virtual key corresponding to the position of the actual mouse cursor is selected, not the position of the virtual mouse cursor, and processes the input. This user selection symbol may be stored in storage 14 or transmitted to a web server through conventional encryption and security processing.

In the specification of the present invention, the actual mouse cursor is an indicator for accurately indicating the path of the user's moving of the pointing means, and the virtual mouse cursor is a virtual indicator moving in a different path from the movement path of the actual pointing means, and the shape or color of each mouse cursor. Can be variously modified. It is preferable to create one or more virtual mouse cursors. The virtual mouse cursor may be generated at random coordinates and move in a random direction. The virtual mouse cursor may be generated at point or line symmetry coordinates of the actual mouse cursor coordinates and move while maintaining a point symmetry or line symmetry state. The virtual mouse cursor may be displayed only within the virtual keypad area or may be displayed on the full screen.

2 is a flowchart illustrating a mouse cursor display method according to the present invention.

The controller 13 displays the virtual keypad on the screen of the monitor 11 in a conventional manner (S201).

When the user generates the event by operating the pointing means 12 (S202), the control unit 13 calculates the coordinates of the actual mouse cursor (S203), and compares the position of the actual mouse cursor with the virtual keypad area (S204). . When the position of the actual mouse cursor enters the virtual keypad area (S204), the coordinates of the virtual mouse cursor are calculated (S205), and the actual mouse cursor is moved to the position of the actual mouse cursor while moving to the actual mouse cursor coordinates calculated in step S203. A virtual mouse cursor is generated (S206). Then, the virtual mouse cursor generated in step S206 is moved with an animation effect to the virtual mouse cursor coordinates calculated in step S205 (S207). Here, the virtual mouse cursor is one or more, step S205 is a step of calculating the coordinates of the number of the virtual mouse cursor to be created, step S206 is to create at least one virtual mouse cursor at the position of the actual mouse cursor at the same time, respectively Moving to the corresponding coordinates.

In this state, when the virtual key selection signal is input from the pointing means 12 (S208), the virtual key selection located at the coordinates of the actual mouse cursor is recognized (S209), and the symbol corresponding to the selected virtual key is input. (S210). If the input to all the symbols is not finished (S211), the flow returns to step S202 to wait for the pointing means 12 to be operated. Here, the input of the virtual key selection signal means that the virtual key is clicked by the pointing means 12 or is dragged while touching the virtual key by the pointing means 12.

If an event occurs by the user operating the pointing means 12 in step S202, the control unit 13 calculates the coordinates of the actual mouse cursor (S203), and compares the position of the actual mouse cursor with the virtual keypad area (S204). . When the position of the actual mouse cursor moves in the virtual keypad area in step S204, the virtual mouse cursor coordinates are calculated (S212), and the actual mouse cursor and the virtual mouse cursor are moved to respective coordinates (S213).

After the step S213, if a virtual key selection signal is input from the pointing means 12 (S208), the virtual key selection located at the coordinates of the actual mouse cursor is recognized (S209), and a symbol corresponding to the selected virtual key is input processing. (S210). If the input to all the symbols is not finished (S211), the flow returns to step S202 to wait for the pointing means to be operated. When the virtual key selection signal is input from the pointing means 12 in step S208, the controller displays on the monitor screen that both the virtual key located at the coordinates of the actual mouse cursor and the virtual key located at the coordinates of the virtual mouse cursor are selected ( For example, the shape or color of the outline of the corresponding virtual keys is changed), and information selected by the user is protected from screen hacking or third-party peeking.

If an event occurs by the user operating the pointing means 12 in step S202, the control unit 13 calculates the coordinates of the actual cursor (S203), and compares the position of the actual mouse cursor with the virtual keypad area (S204). ). If the position of the actual mouse cursor is outside the virtual keypad area in step S204, the actual mouse cursor is moved to the actual mouse cursor position, and the virtual mouse cursor is removed (S214). Then, the process returns to step S202.

3 is a diagram illustrating a process in which a real mouse cursor enters a virtual keypad region and moves to coordinates of a virtual mouse cursor after a virtual mouse cursor is generated according to the present invention.

First, as shown in (a) of FIG. 3, when the pointing means is manipulated so that the actual mouse cursor 31 enters one coordinate V1 of the virtual keypad area, the left and right sides of the virtual keypad area are determined based on the center point and the center line. The line symmetry coordinates V2, the up and down line symmetry coordinates V3, and the point symmetry coordinates V4 are respectively calculated as the coordinates of the virtual mouse cursor. Then, three virtual mouse cursors are generated at the coordinates V1 of the actual mouse cursor 31 while the actual mouse cursor 31 is moved to the actual mouse cursor coordinates V1.

As shown in FIGS. 3B and 3C, the three virtual mouse cursors 32, 33, and 34 are animated while moving to the respective virtual mouse cursor coordinates V2, V3, and V4. Let's do it. As a result, as shown in FIG. 3D, the actual mouse cursor 31 is positioned at the actual mouse cursor coordinate V1, and the three virtual mouse cursors 32, 33, and 34 are respectively the virtual mouse cursor coordinates V2. , V3, V4).

In the present invention, the virtual mouse cursor is generated and moved only when the actual mouse cursor is located within the virtual keypad area. However, the present invention is not limited thereto, and when the virtual keypad is displayed on the monitor screen, the actual mouse cursor and the virtual mouse cursor are displayed. You can also have mouse cursors created at the same time. In addition, in the present invention, the virtual mouse cursor coordinates are calculated to the line symmetric coordinates and the point symmetric coordinates of the actual mouse cursor, but the present invention is not limited thereto.
