Problems solved by technology

In the case of such a pedometer, there is a concern that the acceleration change due to vibration when operating the pedometer, or vibration when detaching the pedometer, etc., may be misjudged as a change in acceleration caused by walking, and displayed on the display device. The counted step value produces an error

Embodiment Construction

[0038] Hereinafter, with reference to the drawings, suitable embodiments of the body motion detection device according to the present invention will be described in detail.

[0039] (Hardware structure of body motion detection device)

[0040] figure 1 It is a block diagram showing the hardware structure of the body motion detection device according to the present invention. Such as figure 1 As shown, the body motion detection device 11 includes a three-axis acceleration sensor that can detect accelerations in three different directions (X-axis direction, Y-axis direction, and Z-axis direction). Here, the three-axis acceleration sensor is represented as an X-axis acceleration sensor 12 that detects acceleration in the X-axis direction, a Y-axis acceleration sensor 13 that detects acceleration in the Y-axis direction, and a Z-axis acceleration sensor 14 that detects acceleration in the Z-axis direction. As the acceleration sensor, a well-known acceleration sensor can be used. The ...

Abstract

A body movement detection device judges a plurality of body movements detected according to regulated gap as continuous body movements and counts the body movements according to continuous detection of the body movements as well as switches and displays number of body movements according to each counting of body movements to display body movement (number of steps) more accurately. Because switch and display of body movements are stopped from period of detecting change of the gestures to regulated time in condition that a gesture change detection portion (44) detects change of gestures in continuous body movement process; when detecting changes, the number of the detected body movements in regulated time is counted and after regulated time, number of body movement counted is added on that of stopped is displayed, therefore accumulation of number of steps corresponding to vibration besides walk with changed gesture is prevented.

Description

Technical field [0001] The invention relates to a body movement detection device. Background technique [0002] Pedometer is one of the body movement detection devices. The pedometer detects the vertical acceleration of the pedestrian through the acceleration sensor, and counts the number of steps (body movement) based on the change in the detected value. In the case of this kind of pedometer, there is a concern that the acceleration change caused by the vibration when the pedometer is operated, or the vibration when the pedometer is disassembled, etc., will be mistakenly judged as the acceleration change caused by walking, and it will be displayed in the display device. The counted step value has an error. In order to avoid these worries, a pedometer has been known. This pedometer detects a change in acceleration that is regarded as continuous walking within a predetermined judgment period, or detects that it is regarded as continuous walking during a predetermined number of j...
