ELECTRONIC DEVICE
First Claim
1. An electronic device to be carried by a user, comprising:
- a first inertial force sensor configured to convert a first inertial force into an electric signal which is output as a first inertial force signal;
a second inertial force sensor configured to convert a second inertial force different from the first inertial force into an electric signal which is output as a second inertial force signal;
an action-mode determiner configured to determine an action mode of the user based on at least one of the first inertial force signal and the second inertial force signal; and
a controller configured to reduce power to be supplied to the first inertial force sensor when the action-mode determiner determines, based on the first inertial force signal or on both of the first inertial force signal and the second inertial force signal, that the user starts a first action.

Abstract
The electronic device, which is to be carried by the user, has a first inertial force sensor, a second inertial force sensor, an action-mode determiner, and a controller. The action-mode determiner determines an action mode of the user based on at least one of a first inertial force signal fed from the first inertial force sensor and a second inertial force signal fed from the second inertial force sensor. When the action-mode determiner determines that the user starts a first action based on the first inertial force signal or on both of the first inertial force signal and the second inertial force signal, the controller reduces power to be supplied to the first inertial force sensor.
