Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a behavior information analysis device that analyzes a user's behavior based on a vibration waveform using an acceleration sensor.

[Prior art and its problems] Conventionally, there has been a so-called 10,000 steps count method that uses vibrations associated with walking motions to count the number of steps. This pedometer is equipped with a pendulum-like weight inside, which detects and counts vibrations caused by walking, and was primarily used for purposes such as health management.

However, this pedometer simply counts the number of vibrations as the number of steps, and cannot determine whether the vibrations are caused by walking, running, or other actions. Therefore, if you perform a work with a different amount of exercise, judge the overall amount of exercise,
There was a problem in that it was impossible to analyze and perform accurate health management.

[Object of the invention] This invention was made in view of the above-mentioned circumstances.
Distinguish and recognize various different actions performed by the user,
It is an object of the present invention to provide a behavior information analysis device that can analyze the overall amount of exercise by storing the motion ω for each motion.

[Summary of the Invention] This invention detects vibrations accompanying motion as a waveform using an acceleration sensor, digitizes the detection results to generate vibration data, and also generates pattern data obtained by digitizing vibration waveforms corresponding to various motions. The pattern data is read out from the stored storage section, compared and recognized with the vibration data, and the recognition result is stored as action data.

[Embodiments 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, 11 is a keyboard for inputting data, controlling the system, etc.
Key operation data No. 1 is sent to the key determination section 12. The key determining section 12 determines the key operated on the keyboard 11 based on the data from the keyboard 11, and sends the data of the determination result to the control section 13. On the other hand, 14 is an acceleration sensor, and vibrations detected by this acceleration sensor 14 are outputted to the A/D converter 15 as a voltage signal.

The A/D conversion section 15 converts the analog value signal sent from the acceleration sensor 14 into a digital value signal and outputs it to the control section 13 . The control unit 13 stores a detection signal input from the acceleration sensor 14 via the A/D conversion unit 15 in a vibration pattern table 16 in synchronization with a timing signal input from the clock unit 17, which will be described later. Compare and match the vibration patterns of various movements.

Then, based on the comparison results, determine the type of behavior,
This behavior data is written into the behavior information memory 18 together with the time data from the clock section 17. Further, in response to key operations on the keyboard 11, the contents of the behavior information memory 18 are read out and sent to the display control section 19.

This display control section 19 drives the display section 20 and controls the control section 13.
Display the input data from.

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

When the user performs appropriate operations after attaching this device to his body, the acceleration sensor 14 detects vibration and sends a voltage signal to the A/'D converter 15 in accordance with the detection result. A,
/' The D converter 15 converts the input analog value voltage signal into a digital value signal and outputs it to the controller 13. The control unit 13 sequentially inputs the input signal from the A/D conversion unit 15 as vibration data to an internal buffer register, and updates the vibration pattern table 16 at a predetermined timing.
The pattern data of various vibration waveforms are read out from the computer and compared and judged. This vibration pattern table 1G stores vibration waveform pattern data corresponding to various operations as shown in FIG. 2, and these pattern data are sequentially read out by commands from the control section 13. In the control section 13,
If it is determined that the input signal from the A, 'D converter 15 is equal to or similar to the pattern data in the vibration pattern table 16, the action data corresponding to the action name of the pattern data is transferred to the timer 17. It is stored in the behavior memory 18 along with the time data sent from the. Also,
If it is determined that the input signal from the A/D converter 15 is completely different from any pattern data in the vibration pattern table 16, it is held as there is no corresponding pattern data, and later predictive action is taken from the previous and subsequent states. is determined. In this way, each time the pattern of the signal input from the acceleration sensor 14 via the A/'D converter 15 changes, the behavior data is written into the behavior information memory 18. The data written in the behavior information memory 18 is stored as data indicating the user's behavior, and if a specific period or more has passed or the data to be stored is limited to the storage capacity of the behavior information memory 18. If the number becomes larger than that, the oldest behavior data will be deleted first.

After that, by operating the keys on the keyboard 11,
The behavior data stored in the behavior information memory 18 can be displayed on the display unit 20 to analyze the behavior.

Furthermore, based on the behavior data in the behavior information memory 18, the user's daily behavior record and daily exercise including the amount of exercise for various movements can be calculated based on the average sleep time, estimated calorie expenditure and required calorie intake, and weight loss. It is also possible to set the difference between the required amount of exercise and other various data to be calculated and analyzed and displayed on the display unit 20.

[Effects of the Invention] As described above, according to the present invention, vibrations accompanying motion are detected as waveforms by an acceleration sensor, the detection results are digitized as vibration data, and vibration waveforms corresponding to various motions are digitalized. ``The pattern data is read out from the storage unit that stores the converted pattern data, compared with the vibration data, and the recognition result is stored as behavior data, so various different movements can be distinguished and recognized, and the By storing the amount of exercise for each movement, it is possible to provide a behavior information analysis device that can analyze comprehensive exercise.
