Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a behavior information analysis apparatus that analyzes a behavior of a user based on a vibration waveform obtained by an acceleration sensor.

[Prior Art and its Problems] Conventionally, there has been a so-called pedometer, which counts the number of steps by the vibration accompanying walking. This pedometer has a pendulum-like weight cone inside, which detects vibrations during walking and counts the vibrations, and was mainly used for the purpose of health management and the like.

However, this pedometer simply counts the number of vibrations as the number of steps, and it was not possible to judge whether the vibrations were due to walking or running or other motions. Therefore, if you perform actions with different momentums, determine the overall momentum,
There is a problem that it cannot be analyzed and accurate health management cannot be performed.

[Object of the Invention] The present invention has been made in view of the above circumstances.
Distinguishing and recognizing various different actions performed by the user,
It is an object of the present invention to provide a behavior information analysis device capable of analyzing a comprehensive amount of exercise by storing the amount of exercise for each action.

[Points of the Invention] The present invention detects vibration associated with a motion as a waveform by an acceleration sensor, digitizes the detection result to form vibration data, and stores pattern data obtained by digitizing a vibration waveform corresponding to various motions. The pattern data is read from the storage unit, compared and recognized with the vibration data, and the recognition result is stored as action data.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to the drawings.

First, FIG. 1 shows the circuit configuration.

In the figure, reference numeral 11 is a keyboard for inputting data, controlling the system, etc., and key operation data of this keyboard 11 is sent to a key judging section 12. This key determination unit 12 uses the data from the keyboard 11
The key operated in 11 is judged, and the data of the judgment result is sent to the control unit 13. On the other hand, 14 is an acceleration sensor,
The vibration detected by the acceleration sensor 14 becomes a voltage signal and is output to the A / D conversion unit 15. The A / D conversion unit 15 converts the analog value signal sent from the acceleration sensor 14 into a digital value signal and outputs the digital value signal to the control unit 13. Control unit 13
Is a detection signal input from the acceleration sensor 14 via the A / D conversion unit 15 in synchronization with a timing signal input from a time counting unit 17 described later, and of various operations stored in the vibration pattern table 16. Compare with the vibration pattern. Then, the type of action is determined based on the comparison result, and this action data is written in the action information memory 18 together with the time data from the time counting unit 17. In addition, the contents of the behavior information memory 18 are read according to the key operation on the keyboard 11 and sent to the display control unit 19. The display control unit 19 drives the display unit 20 to display the input data from the control unit 13.

Next, the operation of the above embodiment will be described.

When the user performs an appropriate operation after attaching the apparatus to his / her body, the acceleration sensor 14 detects vibration and sends a voltage signal to the A / D converter 15 according to the detection result. The A / D converter 15 converts the input analog-valued voltage signal into a digital-valued signal and outputs the digital-valued signal to the controller 13. The control unit 13 uses this A / D
Input signals from the conversion unit 15 are sequentially input as vibration data to an internal buffer register, pattern data of various vibration waveforms are read from the vibration pattern table 16 at a predetermined timing, and comparison judgment is performed. This vibration pattern table 16
As shown in FIG. 2, pattern data of vibration waveforms corresponding to various operations are stored in, and these pattern data are sequentially read by a command of the control unit 13. In the control unit 13, when it is determined that the input signal from the A / D conversion unit 15 is equal to or close to the pattern data of the vibration pattern table 16, the action data corresponding to the operation name of the pattern data Is stored in the action memory 18 together with the time data sent from the clock unit 17. Also, A /
When it is determined that the input signal from the D conversion unit 15 is not equal to any pattern data of the vibration pattern table 16, it is held as no corresponding pattern data,
Later, the behavior is predictively determined from the states before and after that. Thus, every time the pattern of the signal input from the acceleration sensor 14 via the A / D conversion unit 15 changes, the action data is written in the action information memory 18. The data written in the behavior information memory 18 is stored as the data indicating the behavior of the user as it is, and when the specific period of time has passed or when the data to be stored is larger than the storage capacity of the behavior information memory 18. If it happens, the old behavior data will be deleted from the order.

After that, by operating the keys of the keyboard 11, the action data written in the action information memory 18 is displayed on the display unit 20.
Can be displayed on the screen to analyze the behavior.

Furthermore, based on the action data in the action information memory 18, the daily action record of the user, the daily exercise amount including the exercise amount for various actions, the average sleep time, the estimated calorie consumption and the required calorie intake, and the weight reduction are required. It is also possible to set so that the display unit 20 displays and calculates and analyzes various data other than the difference between the amount of exercise and the like.

[Effects of the Invention] As described above, according to the present invention, the vibration associated with a motion is detected by the acceleration sensor as a waveform, and the detection result is digitized into vibration data, and the vibration waveform corresponding to various motions is digitalized. Since the pattern data is read out from the storage unit that stores the converted pattern data, the vibration data is compared and recognized, and the recognition result is stored as action data, various different actions are distinguished and recognized,
By storing the amount of exercise for each action, it is possible to provide a behavior information analysis device capable of analyzing the total amount of exercise.
