In general, desktop computers (hereinafter, referred to as desktops) are input using a keyboard and a mouse. However, portable information devices such as mobile phones do not require a separate input device such as a mouse, which is difficult to carry. A mouse and the like will be provided inside the device.

However, in the portable information devices, consumers who want to enjoy various multimedia such as music, movies, and games have increased. Accordingly, a wider screen is required, and in recent years, a wide screen can be provided while maintaining portability. Front touch screen method is in the spotlight.

Accordingly, although a stylus is provided to easily press the touch screen, this also provides a detachable structure that can be stored inside or a structure that can be suspended on a mobile phone for easy portability.

As such, the UI with convenience without compromising portability has become very important in mobile devices as various usability of the device is required.

These UIs have not been inconvenient when the smartphone performs relatively simple functions yet compared to the desktop. However, as smart phones are getting closer to the computer level, and also when services such as PC remote control are received, the programs in the desktop can be used remotely from the smart phone, thereby enabling the control of desktop applications on the smart phone. I needed a nice UI.

However, all of the UIs for mobile devices introduced to date, such as an operation method using a stylus or a finger gesture, are so different from the operation methods of the desktop, which makes people feel uncomfortable.

The front touch screen is the most ideal to provide a wide screen for enjoying multimedia, but not to impair the portability. If the front touch screen is provided, the buttons and wheels of the mouse can be provided to provide an electronic pen similar to the desktop UI. It is good to use, but it is difficult to apply because users do not like to carry a separate electronic pen on the portable device.

The present invention aims to solve this problem, and proposes an electronic pen which people are willing to carry and carry, and a handheld tablet PC which is operated in pair with it.

In addition, the embodiment consisting of only one body without the USB connection 207 is also possible to achieve the object of the present invention.

In addition, the phone module may be provided in the electronic pen unit instead of the main body unit described above.

The following describes the operation of the electronic pen unit 20 as an input device such as a mouse to the main body unit 10.

The touch pad 23 provided in the electronic pen unit is divided into a left button area 231 and a right button area 232 of a mouse, and a drag signal input to the touch pad 23 is a signal for operating a mouse wheel. In this case, the touch screen can be used as a mouse for a touch screen while directly pressing the touch screen of the main body connected by Bluetooth with the tip 21.

For example, when the user presses the touch screen directly while pressing the right button area 232 of the mouse on the touch pad 23, the right button of the mouse is pressed at the pressed point.

In the drawing, the numeric keys are not displayed on the touch pad 23 for convenience of description, but they also serve as the numeric keypad.

The technology that serves as a numeric keypad as well as a touchpad is already available in the world. Of course, depending on the embodiment, buttons and wheels may be used instead of the touch pad method.

As shown in (a), holding the lower portion 231 of the touch pad and pressing a desired point on the touch screen of the main body is equivalent to pressing the left button of the mouse at the corresponding point.

As shown in (b), holding the upper portion 232 of the touch pad and pressing a desired point on the touch screen of the main body portion is equivalent to pressing the right button of the mouse at the corresponding point.

In addition, dragging the touchpad from the top to the bottom or from the bottom up is equivalent to rolling the mouse wheel from the inside to the outside and from the outside to the inside, respectively.

If the user touches the touch screen of the main body part while touching the right button area 232 on the touch pad 23 of the electronic pen part with the finger, the main body part treats that the right button of the mouse is pressed at the point touched on the touch screen. do.

Next, the basic principle of processing the input of the electronic pen unit will be described with reference to the drawings.

Mouse input mode is started (1000)

When a touch signal is generated on the touch screen of the main body (1100),

Check whether the button state (touch position of the touch pad in the above embodiment) corresponds to the left button or the right button from the electronic pen unit (1200).

If it is the left button, the left button of the mouse is pressed at the point where the touch signal is generated (1300), and if it is the right button, the right button of the mouse is pressed at the point where the touch signal is generated (1210).

Next, a process of processing up to a mouse wheel function will be described.

As the touch pad 23 of the electronic pen unit is dragged from the top to the bottom, or from the bottom to the top, the main body unit receiving the signal processes each signal by rolling the mouse wheel from the top to the bottom or from the bottom to the top, respectively. The example of the figure is an example of processing such a signal by the operation of enlarging or reducing the map.

13 is a process for processing a mouse operation signal of the electronic pen unit in the main body of the present invention

All.

Mouse input mode is started (2000)

When a touch signal is generated on the touch screen of the main body (2100),

Checking whether the button state (touch position of the touch pad in the embodiment) corresponds to the left button or the right button from the electronic pen unit (2200),

If the touch on the touch pad is not a drag state, the left button of the mouse is pressed at the point where the touch signal is generated (2211).

After the left button, if the touch on the touch pad is dragged, the mouse wheel is processed to be dragged (2220).

If the touch on the touch pad is not the drag state, the right button of the mouse is pressed at the point where the touch signal is generated (2310).

While the right button is pressed, if the touch on the touch pad is dragged, the mouse wheel is rolled to be dragged (2400).

In addition, by using the motion recognition signal from the motion recognition sensor built in the electronic pen, the signal touched while tilting to the right may be treated as pressing the right button of the mouse at the corresponding touch point.

Or, press the tip of the stylus vertically, left, right, and back with a constant pressure and recover it when the pressure decreases, and install a switch for each of them to see which direction the tip is tilted and pressed. You can use a sensor that lets you

In addition, the tip of the stylus is not pointed, it is like a flat cut surface or rounded, and the sensor can be used to recognize the degree of inclination according to the part touching the touch screen by arranging the touch sensor evenly at the end. .

Next, various applications of the electronic pen unit will be described.

As shown in the figure, if the electronic pen unit is held by the hand and tilted forward, backward, left and right, the built-in motion recognition sensor may transmit the operation signal to the main body and receive the joystick operation signal from the main body. Also, after disconnecting the USB connector and plugging it into another computer, the electronic pen unit can be tilted back and forth and left and right to input a joystick signal to another computer.

As shown in the drawing, when the electronic pen part is separated into two parts, each of which is held by one hand and tilted, rotated, or swung, the built-in motion recognition sensor sends the motion signal to the main body. It can be received by the main body as a motion recognition signal. In addition, in the case of the embodiment in which the USB connection unit is separately separated as shown in FIG. 6C, after the USB connection unit is plugged into another computer, an operation recognition signal by both hands may be input to the other computer.

Next, various functions using the motion recognition sensor function built in the present invention will be described.

As shown in the figure, when the electronic pen is placed upright and sandwiched between the fingers and the screen is dragged with the finger, the main unit analyzes the signal from the motion recognition sensor and confirms that the electronic pen is laid down to process the input touch signal. Can be processed by screen scrolling.

This function is very useful for checking the corrections with the electronic pen on a document, writing down the correction codes or forwarding items, and scrolling by dragging with a finger when scrolling the screen. This is because when dragging the stylus part according to the conventional method, it is difficult to distinguish whether the document is a line drawing operation or a screen scrolling operation.

This example is a method of processing the eraser mode by recognizing a case where the electronic pen unit is lying down, similar to the above-described function.

This function can be useful in applications such as drawing a computer. If a new touch signal is input while the electronic pen is lying on the input area of the electronic pen, it can be processed by erasing the previously inputted area with a mouse. Can be. Of course, because it works in eraser mode, you can do it by erasing everything that can be erased.

Also, as if using an eraser attached to a pencil, turn the electronic pen upside down and use the upper end to drag in the eraser mode, and dragging your finger with the mouse lying down is handled by moving the screen or charcoal. In the case of drawing using, it can be treated as smearing such a signal by hand.

As shown in the drawing, a line drawn by drawing up the electronic pen unit may be input as a thin line, and a line drawn by laying the electronic pen section at an angle may be inputly processed according to the degree thereof.

This function also needs to analyze the signal from the motion recognition sensor built into the electronic pen and process it according to its inclined angle.

Next, a description will be given of the input processing in the editing area for distinguishing the mode inputted by the tip 21 of the electronic pen unit and the mode inputted by the finger.

The program is started (3000),

When a touch signal is generated in the edit area (3100),

Check the pressed state of the electronic pen mouse button (3200),

If no button is pressed, the mouse pointer is positioned where the touch signal occurs (3210),

If the right button is pressed, the right button of the mouse is treated as pressed (3220),

If the left button is pressed, the motion signal from the motion recognition sensor built in the electronic pen unit is analyzed to calculate the established angle (3300),

If the angle is greater than or equal to the reference angle (the angle is an angle preset in the program, for example, 5 degrees) from the horizontal, the line thickness is processed differently according to the angle according to the angle (3400),

If the angle is equal to or less than the reference angle from the horizontal, it is processed as an input by a finger (3310).

The present invention is not limited to the scope described herein, but many modifications having the same basic technical spirit should be included in the scope of the present invention. The basic technical idea of the present invention is to have a operating system supporting a wireless mouse (electronic pen) that points in a stylus manner, and has a small computer main body having a front touch screen, and connected to the main body to serve as a handset or / and a headset.
