The temperature sensor control device of this embodiment measures the body temperature by lightly pressing the temperature sensor 102 against the skin surface, so that it is easy to hold with one hand, and is a pen-type thermocouple (infrared ray Not) type was used. When the temperature of the temperature sensor reaches a specific value, a device capable of freely adjusting the temperature is used as a trigger for switching or terminating the screen.

FIG. 2 is a flowchart for explaining the operation of the temperature sensor control device shown in FIG. Less than,
Description will be made based on this flowchart.

[Step S1] When activation of the temperature sensor control device is started, first, an initial screen is displayed on the display device 107 in accordance with a command from the control device 101. This initial screen is
For example, as shown in FIG. 3, it is composed of an image in which the positions of a plurality of (m) pots are accurately shown on a background image such as a hand or a foot, which is a part of a human body.

The order of the pots to be measured is determined by the control device 101 at the time of activation. Pot N in order of measurement

Initialize to 1.

[Step S2] First, in order to clearly inform the subject of the position of the crucible for which the temperature is to be measured first, the moving picture processing unit 105 plays the moving picture as if the target crucible is blinking. create. The subject measures the temperature by bringing the temperature sensor into contact with the same hand position as the object on the screen where the blinking has started.

[Step S3] The control device 101 starts initialization of the temperature sensor 102,
2. Start taking temperature from 2.

[Step S4] It is determined whether or not to end the temperature measurement of the object. That is, temperature data is input from the temperature sensor 102 at a sampling period of 250 ms and stored in the memory 106. further,
The arithmetic processing unit 104 compares and analyzes the temperature data to determine whether or not the temperature measurement of the object has been completed.

FIG. 4 is a graph for explaining how to determine the temperature of an object based on a change in temperature data.

First, before the temperature sensor 102 is brought into contact with the skin surface, the temperature data is room temperature, as shown in the graph of FIG. 4, but when the temperature sensor 102 is brought into contact with the skin surface, a few seconds later. , Reach skin surface temperature. Further, after that, when the temperature sensor 102 is separated from the skin surface,
After a few seconds, return to room temperature again.

From the characteristics of such temperature change, the timing of ending the measurement of the object is determined, and the temperature of the object is extracted. Maximum value of stored temperature data (max
temp) is calculated every time one data is read. For example, 27.3, 27.6, 27.8, 28.2, 29.
4, 29.9, 30.1, 30.4, 31.5, 32.
The maxtemp of 5 and 33.5 is 33.5 ° C. and 2
7.3, 27.6, 27.8, 28.2, 29.4, 2
9.9, 30.1, 30.4, 31.5, 32.5, 3
The maxtemp for 3.5 and 34.2 is 34.2 ° C.

Next, when separated from the skin, 27.3, 27.
6, 27.8, 28.2, 29.4, 29.9, 30.
1, 30.4, 31.5, 32.5, 33.5, 34.
Since the temperature starts to drop to 2,33.9, maxte
mp does not change and reaches 34.2 ° C.

When the value obtained by subtracting the latest temperature data from the maximum value (maxtemp) is less than a predetermined value (for example, 0.8) (in the case of NO), for example, 27.3, 27 .6, 27.8, 28.2, 29.
4, 29.9, 30.1, 30.4, 31.5, 32.
5, 33.5, 34.2, 33.9, 34.2-3
In the case of 3.9 = 0.3, since 0.3 <0.8, it is considered that the measurement is still being performed, and the process proceeds to step S10. maxtem
If the value obtained by subtracting the newest temperature data from p is equal to or greater than a predetermined value (for example, 0.8) (in the case of YES), it is determined that the measurement of the object has been completed and maxt
Determine emp to the temperature of the object.

That is, 27.3, 27.6, 27.8, 2
8.2, 29.4, 29.9, 30.1, 30.4, 3
1.5, 32.5, 33.5, 34.2, 33.9, 3
In the case of 3.2, 34.2-33.2 = 1.0 1.0
Since it is> 0.8, it is determined that the measurement has been completed, and the process proceeds to step S5.

[Step S5] It is determined whether the temperature measurement has been completed normally. maxtemp is determined as the temperature of the object, and this temperature is hereinafter referred to as Temptn.

Temptn = maxtemp Determines whether Temptn is appropriate as the temperature of the object. In other words, if the pressure for pressing the temperature sensor against the skin is too weak or only touches for about one second, Temptn becomes less than a predetermined value (for example, 32.0 ° C.), and It is judged that it is not appropriate as skin temperature. If Temptn <32.0 (NO), the process proceeds to step S6 and Temptn
If n> = 32.0 (YES), step S7
Proceed to.

[Step S6] A dialog (see FIG. 5) for allowing the subject to determine whether or not to re-measure the object is displayed on the display device 107, and the temperature of the temperature sensor 102 is changed to room temperature or skin temperature. Temperature (15 degrees to 40 degrees)
As a trigger for switching to a temperature other than the above, the processing for “YES” and “NO” is performed, respectively. That is, when measuring the blinking object again (YE
In the case of S), for example, a container in which the tip of the temperature sensor can be put is prepared, and the temperature sensor 102 is brought into contact with the side where "YES" is written.

A device capable of maintaining a constant temperature is installed in the container, and the temperature is set to about 10 degrees. When the temperature data changes from room temperature to 10 degrees as a trigger, the process returns to step S2. When canceling (in the case of NO), the sensor is brought into contact with the side where "NO" is written. In this case, the temperature in the container is set to around 45 degrees, and when the temperature changes from room temperature to 45 degrees as a trigger, the process proceeds to step S7.

[Step S7] Te obtained in step S5
The value of mptn is displayed near the blinking object on the screen (see FIG. 6). When the measurement is not completed normally, for example, when Temptn = 28.5,
“NG” is displayed at the same position. (See FIG. 6) [Step S8] The blinking of the object for which measurement has been completed is terminated, and the color of the object is changed to red. This makes it possible to clearly distinguish between a measurement-completed pot and an unmeasured pot.

[Step S9] The object is incremented. That is, tn = tn + 1 is performed, a crucible to be measured next is set, and the process returns to S2.

[Step S10] It is determined whether to end the program. That is, first, the temperature and the maximum value ma
The difference of xtemp is a predetermined value (for example,
0.8) or higher, it is either the sensor is still attached to the skin (during measurement) or the temperature sensor is left at room temperature and measurement is not being performed. If it is determined that this state has continued for one minute or more, a dialog urging the end of the program is displayed. (Refer to FIG. 7) “YES” and “NO” are selected only by the temperature sensor as in the dialog in step S6. "YES"
When the sensor is put in the container of (1), the process proceeds to step S11,
If the sensor is put in the container of "NO", the process goes to step S4.
Return to and continue the temperature analysis.

[Step S11] Before terminating the program, the measured temperatures of all the pots are compared and analyzed with statistically collected data and known information of Oriental medicine. If the temperature of the pot is significantly lower than the average temperature, it is determined that the pot is cold or may cause back pain, and advice on such diagnosis is displayed.

[Step S12] The temperatures of all the pots measured so far are stored in the memory device 106 as a file.

[Step S13] The control device 101 ends the image editing in the moving image processing section 105, erases the screen, and ends the processing of the entire device.

(Embodiment 2) In Embodiment 1, the subject is
Although the embodiment of the device for measuring the temperature of the skin has been described, the present invention is not limited to the case of measuring the temperature, but can be used as a new interface corresponding to a mouse click or the like. That is, a mouse,
If the keyboard cannot be operated by a user who cannot operate with the keyboard, for example, a handicap or other handicap, use tools that are safe to hold on to the mouth or that are fixed to the arm. Just by installing, you can use the temperature sensor. Further, it is possible to increase the number of menu items by devising the shape of the container in contact with the sensor and increasing the temperature setting.

(Embodiment 3) In Embodiment 3, a description will be given of a drawing system for infants, in which the color changes with the temperature change of the temperature sensor.

It is possible to play on a computer as if it were a brush-up or a water painting. The temperature value of the temperature sensor is converted into a color type, and the speed of change is converted into a color density.
That is, as shown in FIG. 8, when a draft is displayed on the screen and a pen-type temperature sensor is put in containers 1-4 such as paint, the color of the picture portions 1-4 having the same number as the containers 1-4 is changed. Will follow. Since the degree of change varies depending on the pressing strength of the temperature sensor, the color density also changes in real time. Even children under the age of three who are not good at coloring can still enjoy it with simple operations.
