Abstract

1. TECHNICAL FIELD OF THE INVENTION

Writing tool for computer.

2. Technical problem to be solved by the invention

It keeps the user's writing style intact, enabling detailed writing on the computer screen.

3. Summary of Solution to Invention

Dividing a person's handwriting into 'hand movement' and 'finger movement' means that the movement of the hand is the amount of movement of the moving plate on which the hand is placed (possible to measure the position), and the movement of the finger in the writing window area on the moving plate. By measuring the position of the writing point (point where the position sensor and pen touch the pen), the information is transmitted to the computer so that detailed writing can be performed on the screen.

4. Important uses of the invention

The reason why PC communication is impossible for Chinese people is not only because of low PC penetration rate but also because Chinese is composed of numerous hieroglyphs. In order for a proud Chinese to chat without having to learn English, there is no other way than to write and send hieroglyphs directly to the computer. This invention provides the basic principle of a tool for easily entering both pictures and text into a computer.

Description

Computer writing tools that can easily express even minute handwriting

A technology related to a computer drawing work peripheral device. A representative example of the related art is to measure the rolling speed of a ball by the movement of a user's hand every minute, and then move the mouse pointer on the computer screen by a distance corresponding to the speed. An ordinary mouse that delivers to a computer.

A widely used mouse can easily transfer large hand gestures to a computer, but it is impossible to express writing that requires precise work. The reason is that writing with a mouse is like writing a piece of paper with a pencil held down with a finger. Chinese is made up of a number of hieroglyphs that can be typed on the keyboard, but it will be tiring for the user (Chinese). As a result, word processors and communication programs for Chinese people need peripherals that allow them to input hieroglyphs directly from the user. The object of the present invention is to enable accurate computer writing as if writing on paper by maintaining the natural writing of a person.

Figure 3 shows a schematic of a 21st century mouse.

(Ⅰ) Basic principle

The information on a person's hand holding a pencil and writing on a paper can be divided into three categories:

① Angle of wrist.

(2) The position of the area where the blade, including the little finger, touched the paper. (Replace this area with a single point to represent the position of the hand. From now on, the representative hand position will be referred to.) Reference is a fixed point on the paper)

③ The position of the writing point (point where the tip of the pencil touched the paper) measured based on the representative hand position.

Measuring human writing by dividing it into the above three criteria enables the user to express fine writing on the computer screen, and the core of this principle is 'total movement of the hand' and 'finger movement' while maintaining the natural handwriting of the person. The movement of a writing point by 'is measured relative to each other from different standards and expressed on a computer screen.

(Ⅱ) Organization of the instruments necessary to measure the above three pieces of information and write on the computer screen

① Bottom plate: Corresponds to the computer screen.

②Moving board: Move the place where hands are placed and the bottom plate.

③Writing window: It is a part of the moving board, where writing utensils touch and actual writing takes place. In Figure 1, the moving plate moves on the bottom plate and the writing plate is attached to the moving plate. The contact area with the blade is the reach of the user's hand holding the writing implement on the moving plate.

(Ⅲ) action

In Fig. 1, the tilting angle of the movable plate is obtained by measuring the positions of the arbitrary anchor points b and c on the movable plate based on the arbitrary anchor point a on the base plate. Points B and C show the instruction box (hereinafter referred to as the writing area display box) that displays the area of the writing window on the computer screen in a similar manner using the position and the tilt θ. Assuming that the representative hand position is a point b (any point on the moving plate), measure the position of the point d (writing point, where the writing is made) based on the point b, and then add it to the point b. On the computer screen, the handwriting is taken and an arrow indicating the position is indicated. As a result, the instruction box indicates the movement of the user's hand (the movement of the movable plate on the bottom plate) and the arrow indicates the movement of the finger (the movement of the writing point in the writing window).

The figure shows the user finishing writing the letter 'C', and the writing window shows the movement of the writing point as a dotted line, but nothing is actually written.

Here, multiplying the measured position by an arbitrary amplification ratio enables both enlarged writing (amplification ratio> 1) and reduced writing (amplification ratio <1). The position is represented by an amplification ratio of 1, so that when writing on a computer, the user can move the hand in a narrow area while writing in detail throughout the screen.

In addition, in the above, the position of the moving plate was measured from the fixed point (point a) of the bottom plate, but since the movement of the hand does not have to be accurate in the writing operation (the error in the movement of the hand in the actual writing operation is determined by the movement of the finger). It is preferable to move the indication box displayed on the screen by measuring the movement amount like a normal mouse (in fact, it measures the movement speed every moment and moves it by that size).

The shape of the writing window is shown as a rectangle in the picture, but for tools that can be used for drawing, the shape should be any area where a person can hold a hand on the floor and draw a line comfortably with only a finger movement. The shape of the box resembles the shape of the writing window. The moving plate in Figure 3 is a schematic model of this ergonomic writing window.

(Ⅳ) Structure and function of application products (21st century mouse)

Figure 3 shows the shape of a mouse that enables detailed computer handwriting by using the above method (measured by dividing a person's handwriting into the overall hand movement and the writing point's movement on the moving plate). . The amount of movement of the moving plate is measured using the principle of the mouse (in this case, only the position of one point on the moving plate can be known, so the tilt of the moving plate cannot be obtained. Direct input from the user is provided). The position of the writing point in the writing window is measured using a measuring sensor (optical sensor or magnetic sensor) (in this case, the optical sensor is used together with the laser pen and the magnetic pen if the magnetic sensor is used). The writing area display box is moved on the screen, and the position of the writing point in the writing window corresponds to the position indicated by the arrow in the writing area display box on the screen.

Since the writing area display box of the screen is moved by measuring only the movement amount without measuring the position of the moving plate on the bottom plate, if the writing area display box is located where the user does not want, the writing area display box moves even if the moving plate is moved. 'Non-functional' is required. In the current widely used mouse, a user performs a 'lifting operation of the mouse' to solve this problem. The mouse of the present invention cannot lift a moving plate because the user always holds a pen. Magnetic levitation is used to solve this problem. Electromagnets are arranged in the entire bottom plate and the four moving plates, and the electromagnets of the bottom plate and the moving plate face each other with the same poles. If the user raises his hand slightly, the moving plate will be injured. If the moving plate moves in this state, the sensor of the moving plate cannot measure the moving amount, and the writing area display box on the screen will not move.

The airbag (cushion role) is widely attached to the part where the user's blade touches on the moving plate to relax the user's hand, and the pressure sensor is attached below the air pocket. Power on the mouse (external power for writing windows, pens, and electromagnets) is turned on, and when the pressure on the pouch is lowered by removing the hand from the moving plate, the power is turned off.

In addition, there is a 'writing window cover' to cover the writing window, which is equipped with the left and right buttons of the mouse, and the cover can be used in the same way as a normal mouse. (The figure below shows the writing window covered)

By maintaining the writing habit of love, detailed writing is possible on the screen of the computer, and by varying the amplification ratios for the movement of the moving plate and the moving of the writing point (moving plate amplification ratio> 1, the writing point amplification ratio = 1) You can write detailed writing on the whole screen while moving your hand within a small range (compared to the computer screen).
