Embodiment Construction
[0021] Hereinafter, an embodiment in which the technical idea of the present invention is applied to an activity meter for measuring the amount of physical activity will be described with reference to the drawings.
[0022] The activity meter of this embodiment has a small structure that can be worn by the user on the waist and used as described later, and includes figure 1 circuit as shown.
[0023] This activity meter includes a three-axis acceleration sensor 1 as a body motion detection mechanism for detecting body motion of a user, an arithmetic processing unit 2 composed of a microcomputer, an A / D conversion unit 3, an input operation unit 4, and a display unit 5. , storage unit 6, and battery power supply unit (not shown).
[0024] The acceleration sensor 1 is, for example, a three-axis acceleration sensor that outputs accelerations of three axes perpendicular to each other in an analog form. As such an acceleration sensor 1 , an acceleration sensor utilizing a small...
