Problems solved by technology

In this way, in the case of a pedometer that counts the number of steps by comparing the acceleration detected by the acceleration sensor with a predetermined threshold value, it is often difficult to count the number of steps accurately.
On the other hand, in the pedometer of the method of measuring the number of s

Embodiment Construction

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0018] (A: Composition)

[0019] figure 1 It is a block diagram showing a configuration example of a mobile phone 10 functioning as a pedometer according to an embodiment of the present invention. The cellular phone 10 includes a control unit 110, a mobile phone, a control unit 110, and a wireless communication unit for wireless communication with a base station of a mobile phone network (both are omitted) in addition to a voice input and output unit for inputting and outputting a call voice or a wireless communication unit for wireless communication with a base station of a mobile phone network. Sensor 120 , operation unit 130 , display unit 140 , storage unit 150 , and bus 160 linking data transmission and reception between these components.

[0020] The control unit 110 is, for example, a CPU (Central Processing Unit). The control unit 110 executes various program...

Abstract

The invention provides a pedometer and a program. whenever an output signal of an acceleration transducer is detected to a reducing from an increasing(e.g. being a peak value), the peak value is compared with a first threshold value, and a time interval between the peak value and the detection timing of the previous peak value is compared with a second threshold value to judge whether to count the step number, and then, the detected peak value is compared with a third threshold value greater than the first threshold value, and a time interval between the peak value and the previous peak value is compared with a fourth threshold value representing a time shorter than the second threshold value to judge the action type of users(e.g. running, walking or other state). Under the situation of being judged as running or walking, the falling steep degree of a wave form after appearing a peak in an acceleration time waveform is estimated according to the judged result, and the step number is added up according to each action type.

Description

technical field [0001] The present invention relates to a pedometer for counting the number of steps of a user, and more particularly to a pedometer for detecting a step of a user by using a motion sensor such as an acceleration sensor. Background technique [0002] Conventionally, such pedometers have been known. And, as this kind of pedometer, there is a type that detects one step of the user based on whether a characteristic pattern appears on the output waveform of the acceleration sensor (Japanese Patent Laid-Open No. 2006-039971 and Japanese Patent Laid-Open No. 2006-127192 Publication No. 2007-115242, Japanese Patent Laid-Open No. 2007-115243, Japanese Patent Laid-Open No. 2007-115242 and Japanese Patent Laid-Open No. 2008-262522, JP 2006-118909, JP 2006-293860, and JP 2008-250964). [0003] However, for the user of the pedometer, the state of running (a state of movement in which both feet are suspended in the air) and the state of walking (a state of movement in w...
