Abstract

PURPOSE:To operate various functions on one board without looking at the board by storing, processing, and deciding detection signals from sensors arrayed on the board in a matrix, and setting and inputting numerals or instructions corresponding to a trace drawn on the board. CONSTITUTION:Detection signals from plural pressure sensors 2 of matrix constitution on the board 1 are supplied to a storage means and the coordinates of sensors which detect the starting and ending positions of the trace drawn on the board and the number of sensors which detect the trace are stored. In this case, (m) sensors 2 in an X-axis direction and (n) sensors in an Y-axis direction, i.e. (mXn) sets in total are arrayed. When pressure is applied from above a sheet 3 covering the pressure sensors 3, each sensor 2 at the position generates a detection signal. This signal is read out in series or in parallel and supplied to a computer 4. The computer 4 decides the trace that a user draws by pressing the board I as shown by arrows I a, I b...Vb, and outputs numerals or instructions corresponding to the trace.

Description

[Detailed description of the invention] The present invention (: 1, 1 thread on the board switch, 71 threads on the board
- Detection of arranged Renri 1. ) By memorizing and inputting the number 1 or command that corresponds to the locus drawn on the board J-, you can operate the board without visually checking it and use various functions. The purpose of the present invention is to provide a board switch that can be operated using a board and is simple in design.

Generally, switches (or switches) are provided for a single function, such as turning the power on and off.For this reason, a switch for inputting decimal numbers from "0" to "9" requires 10 switches. This operation requires visual inspection of the switch.

This number 1i (J input switch is set to automatic, etc.)
When calculating the distance l1lItδ1, etc., it is dangerous to visually check the switch while driving, and the switch is not suitable for a visually impaired person to operate.

In addition, switches for the lie 1-9 directional support, wiper, etc. of the automobile are also separately installed, which has the disadvantage that the installation positions of these switches are limited.

The present invention eliminates the above-mentioned drawbacks, and an embodiment thereof will be explained with reference to the drawings below.

FIG. 1 does not show the overall components of the board switch according to the present invention. The detection signals of the plurality of U-leathers 2 formed in a matrix on the board 1 are supplied to a storage means, where the respective coordinates and trajectories of the start and end positions of the trajectories drawn on the board 1 are detected. The number of lenses created is memorized.What is the method of performance?) The start of 1 trace is 1! The inclination and distance i of the straight line connecting the coordinates of the defense and end positions are determined, and the discrimination means is used to record [! , 1 and the distance 1, and the PIT marks at the starting position F'l and the ending position according to the inclination, a numerical value or command corresponding to the J:ri trajectory is set and input.

FIG. 2 is a block system diagram of an embodiment of the board switch according to the present invention. In the figure, 1 is a board, and its -
There are (1) on the surface as shown in Figure 2 (the lower left corner is at the coordinates (1, 1) and there are m pieces in the X-axis direction (right direction).

In the Y1111 direction (upward)
Ill X Eleven pressure lenses 2 are arranged in a matrix. The plurality of pressure hinges 12 are covered with sheets 3, and when pressure is applied from - of the seats 1 to 3, each pressure hinge 2 at the position where pressure is applied generates a detection signal 15. . Detection signals generated by the plurality of pressure sensors 2 are read out serially or in parallel and supplied to the computer 4. Computer 4 is indicated by arrow ■a.

(2) As shown in b, .

Figure 3 is a combination] - Accept the flowchart 1 of the program to be executed on evening 4. This program is started by receiving a detection signal from the board 1. In step 10, the second
The coordinates (i 1 , j + ) of the IJ11 start position and the coordinates (i 2 , j 2 ) of the end position of the trajectory drawn by pressure welding as shown by the arrows a to vb in the figure are retrieved and stored, and then the start position of the trajectory is The number C of pressure sensors 2 that have generated detection signals from the time to the end is counted and stored.

Next, in step 11, the slope SL and distance DI of the straight line from the coordinates (i H, j + ) to the coordinates (!2.j2) are calculated. In step 12, the number of pressure sensor 2 that should exist between the distance DI and the number C are compared. For example, if the number C corresponds to more than twice the distance DI, the locus is classified by 1'11, such as a circle. Ru. In the case of a circle, the process moves to step 133, where x coordinate i1. i2 are compared with each other, and if the The rotation in the direction, that is, the trajectory Va, is determined, and rOJ is set in the variable Δ. If it is determined in step 12 that the shape is not a circle, the slope SL is compared with a predetermined value in step '14, and the slope SL-
When is in the range from approximately =0.4 to -2.4, it is tilted to the right. After this, in step 15, Y PK ++j J +
+ J 2 is compared and Y (when gj1 becomes a person, it goes down to the right)
8" is set, Yl・p, 14; i J 2 is person 4
r is upward left, that is, the trajectory Iva is returned to variable A, which is 1
7" is set.

Next, A: If there is no i slope C, then in step 1G the slope Sl-
can be compared with the givenness, and this slope S' is approximately -0,4 to 0
, 4. This i (X coordinates i,,i2 are compared at the snowtube 17, and
'' is set, and when the X coordinate 12 is a person, it is assumed that the direction is to the right, that is, the trajectory ma, and the variable A is set to 15''. If it is not horizontal, the slope SL is compared with a predetermined value in step 18, and if the slope SL is within the range of about 0.4 to 2.4, it is determined that the slope is leftward. After this, in step 19, the Y coordinate j+,
j2 is compared and the Y coordinate j! When the Y coordinate j2 becomes large, it is determined to be downward to the left, that is, the trajectory nb, and variable A is set to "4." When the Y coordinate j2 is large, it is determined to be upward to the right, that is, the trajectory [a, and variable A is set to "3." Further, if it is not tilted to the left, that is, if the tilt is greater than or equal to 2.4 -L or less than -2.4, it is determined to be vertical, and in step 20, a5, the Y coordinates j+ and j2 are compared, and when the Y coordinate j1 is human, it is determined to be vertical. In other words, the trajectory 1b is set and the variable A is set to 12, and when the Y coordinate j2 becomes large, the trajectory is set to rise, that is, the trajectory 1a, and the variable A is set to 1.

After setting the variable A to any value from "0" to "9" as described above, in step 21 it is determined whether any point on the board 1 shown in the second figure is pressed and a point is struck. If it is determined and a dot is scored, the numerical value set for the accident △ is input, and the IR recognition 1 = first f- is sounded.

In this way, read 10 numbers from C "0" to "9" corresponding to the locus of pressure contact with small wire 1 (2 and 2 are obtained,
No matter which part of the board 1J- the pressure welding operation is performed on, the numerical value can be determined (1R or C), so it is necessary to visually check the board 1 and determine the <;< , It is suitable for switches such as automobiles or visual disturbances.Also, the above change? (Instead of setting ``0'' to ``19'' in For example, it is possible to set commands such as turning lights on and off during automatic operation, and to override various functions such as the driver, direction support, and wiper.

Historically, since it is a single board 1, the design is concise and the design is similar to that of the previous board.

<j Oh, you can use a light sensor, temperature sensor, etc. instead of the pressure sensor 2. In addition, the number 1 that corresponds to the trajectory of the input "acknowledgement" sounds the buzzer, and also synthesizes the voice.
G or the command may be outputted by voice, and the present invention is not limited to the above embodiment.

As described above, the board switch according to the present invention has a plurality of sensors arranged in a matrix on a single board, each of which generates a detection signal corresponding to a trajectory drawn on the board, and a starting position of the trajectory. and a storage means for storing the coordinates of each sensor at the end position and the number of lenses that have detected the trajectory; a calculation means for calculating the inclination and distance of a straight line connecting the coordinates of the start position and the end position; The trajectory is determined by comparing the distance and the coordinates of the start position and end position according to the inclination, and the board No matter where you draw a trajectory, you can determine the numerical value or command that the trajectory represents, and there is no need to visually check the board during operation. When setting and reading commands corresponding to the ``-'' board, various functions can be operated on the ``-'' board, and since it is a ``-'' board, the pre-installation is simplified.
