Abstract

PURPOSE:To improve the working efficiency of a keyboard input device by controlling a pointing device cursor on a display device in accordance with the tilting degree and the tilting direction of a key. CONSTITUTION:The tiling degree and direction of a key 1 are detected by the tilt detecting pressure sensors 2 set in the different directions. A tilt detecting part 5 calculates the tilting degree and direction of the key 1 based on the output signals of sensors 2. Based on the information received from the part 5 and the cursor position information, a cursor position calculating part 71 decides a new cursor position and sends it to a display information generating part 72. As a result, a pointing device cursor 81 moves in the tilting direction of the key 1 on a display device 8. Meanwhile an input character detecting part 6 outputs an input character code when the input of characters is detected by a character input detecting pressure sensor 3 with push of the key 1. The input character code is given to the part 72 and the input characters are shown on a display device 8. Thus the cursor 81 is controlled with the operator's hands kept on a keyboard input device 9.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention realizes character input and movement control of a pointing device cursor on a display device used in various processing devices such as electronic computers, GS terminals, and workstations. This invention relates to a keyboard input device.

[Conventional technology]

Figure 3 is an example of "Fujitsu FM16-β System Manual"
This figure shows the configuration of an input device including a pointing device in the conventional computer shown in FIG. T is the main body of the computer; 71 is a cursor position information calculation unit that calculates and requests the position of the pointing device cursor on the screen; 72 is a display information generation unit that generates display data for a display device; 8 is a display device; 81 is a a pointing device cursor; 9 a keyboard input device used for inputting character information into a computer; 6 an input character detection unit that detects input character information from the keyboard input device; 1
0 is a pointing device that instructs the movement of the pointing device cursor.

11 is a pointing device movement detection unit that detects movement of the pointing device.

Next, the operation will be explained.

Character information input from the keyboard input device 9 is taken into the input character detection section 6 and converted into a character code. On the other hand, if the user wants to move the pointing device cursor 81 on the display device, the user releases the keyboard input device 9.

Move the pointing device 10 connected to the computer main body. Pointing device movement detection section 11 detects the movement direction and movement amount of pointing device 10 . Based on the detection result of the pointing device movement detection section, a cursor position information calculation section T1 calculates the position of the pointing device cursor after the movement and passes it to the two-display information generation section T2. Here, together with the character information sent from the input character detection section, information to be displayed on the display device is generated, and as a result, the characters displayed on the display device or the position of the pointing device cursor are changed. Here, the handling of the keyboard input device 9 and the pointing device 10 are completely independent, and therefore, the user uses the keyboard input device and the pointing device, which are different and independent devices, to input characters and request movement of the pointing device cursor. It was necessary to input the following information.

[Problem to be solved by the invention]

In the conventional combination of a keyboard input device and a pointing device, the user moves the pointing device cursor 81 while inputting character information using the keyboard input device 9.
If you need to move.

After once removing the hand from the keyboard input device 9 and operating the pointing device 10 to determine the position of the pointing device cursor, it was necessary to return the hand to the keyboard input device 9 and continue inputting character information. For this reason, if the user frequently operates the pointing device during work in which the user makes large hand movements during input operations, the work is repeatedly interrupted, leading to a decrease in work efficiency.

In addition, since blind touch input is performed while moving the positions of the two hands, there is a tendency for many erroneous inputs to occur.

This invention was made in order to eliminate the above-mentioned problems, and in addition to the character input function inherent to a keyboard input device, it also uses information on the inclination input to the keys on the keyboard input device to perform pointing. By realizing operations equivalent to operations using a device, it is possible to control the pointing device cursor while leaving one hand on the keyboard input device.

The aim is to improve work efficiency.

[Means to solve the problem]

Keys that can tilt forward, backward, left and right, and move up and down,
A keyboard input device with a tilt detection function, which includes a tilt detection pressure sensor that detects tilt information of the key as an electrical signal, and a character input detection pressure sensor that detects character input by the key, and an output signal of the keyboard input device. The keyboard includes a key inclination detection section that detects the direction and amount of inclination of a key, and an input character detection section that detects character information input from the keyboard input device.

[Effect]

The keys of the keyboard input device in this invention.

By tilting the pointing device cursor in a desired direction, the direction and amount of tilt of the key are detected by tilt detection pressure sensors for each direction and output as electrical signals. In the tilt detection section.

Calculating the direction and degree of the key inclination from the output signal,
A new cursor position is determined by the pointing device cursor position calculation unit based on the information from the tilt detection unit and the previous cursor position information.

Pass it to the display information generation section. As a result, the pointing device cursor on the display device moves in the direction in which the key is tilted.

On the other hand, when the key is pressed and the two-character input detection pressure sensor detects that a character has been input.

The input character detection section outputs an input character code. The code is passed to the display information generation section, and the input characters are displayed on the display device.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 1 indicates each key of a keyboard input device. 2 indicates a tilt detection method that detects the upward direction and amount of tilt of the key and converts it into an electrical signal. Pressure sensor 3 is a character input detection pressure sensor that detects when the key is pressed and a character is input.

Further, in FIG. 2, 4 is a keyboard input device with a tilt detection function configured by the key, and 5 is the direction of the tilt input to the key based on the electrical signal regarding the key tilt obtained from the keyboard input device. , a key inclination detection unit that calculates the amount of inclination, and 6 an input character detection unit that detects that a character is input from the keyboard input device and obtains its character code.

T is an electronic computer that receives input information from the keyboard input device, and 71 is a voice/teaching device cursor position M after movement based on the information obtained from the key tilt detection section and the previous pointing device cursor position information. A cursor position information calculation unit 72 for obtaining information places the cursor at a new pointing device cursor position obtained as a result of the cursor position information calculation unit, and displays the character information obtained from the input character detection unit on a display device. A display information generation unit that generates information; 8 a display device that displays information generated by the display information generation unit; and 81 a pointing device cursor.

Next, the operation of one embodiment of the present invention will be explained.

Suppose that a computer user wants to move the pointing device cursor 81 on the display device 6 toward the front right.

In this case, the computer user tilts the keys of the keyboard input device 4 forward to the right.

When the key 1 is tilted forward to the right, the tilt detection pressure sensor 2 converts the amount of tilt of the key in each of the front, back, left, and right directions into electrical signals and outputs the electrical signals. Here, since the key is tilted forward to the right, the forward tilt detection sensor 21 and the right tilt detection sensor 22 detect the tilt among the tilt detection pressure sensors 21 to 24 for each direction shown in FIG. Then, the degree of the slope is converted into an electrical signal and output. The output signal is demodulated by the key tilt detection section 5 into the key tilt direction θ and the key tilt Jlv using a quadratic equation.

The information is sent to the computer main body 7.

The tilt amount V of these keys is the pointing device cursor 8
It is used as information representing the moving speed of 1. That is,
As the amount of inclination of the key 1 increases, the moving speed of the pointing device cursor 81 increases. The cursor position information calculation unit T calculates new Kahnle position S information from the key inclination direction θ, the inclination 1v obtained from the tilt detection unit, and the previous cursor position information, and the result is sent to the display information generation unit. Pass it to T2.

On the other hand, when the key 1 is pressed downward, the nine character input detection pressure sensor 3 outputs an electrical signal indicating character input. The signal is passed to the character input detection section 6.

The input characters are identified here and a 9-character code is output.

Based on the character hood generated as described above and the cursor position information, the 1 display information generation unit T2 generates display information to be newly displayed, and as a result, the display device 8
A new pointing device cursor 81 and input characters are displayed.

Although the above embodiment does not specifically show the arrangement of the keys that can detect the tilt, all the keys of the keyboard input device M4 may be able to detect the tilt, or only some keys of the keyboard input device M4 can detect the tilt. A sufficient effect can be obtained even if the key has the ability to detect the tilt of the key.
