Abstract
A position change unit includes a movable unit and a drive unit configured to drive the movable unit so as to carry out reciprocating motion in a direction in parallel to a front surface of a housing. At least one processor is configured to control the drive unit. With reciprocating motion of the movable unit in which an acceleration in movement in one direction is higher than an acceleration in movement in the other direction, a moment rotating a portable device in a first direction of rotation is generated around an axis in parallel to the front surface of the housing and perpendicular to a direction of reciprocating motion.
Claims10
A portable device, comprising:
- a housing;
- a display located on a front surface side of the housing;
- and
- a position change unit located in the housing and configured to change a position of the portable device which is falling,
- the position change unit including
- a movable unit,
- a drive unit configured to drive the movable unit so as to carry out reciprocating motion in a direction in parallel to a front surface of the housing, and
- at least one processor configured to control the drive unit, and
- with reciprocating motion of the movable unit in which an acceleration in movement in one direction is higher than an acceleration in movement in the other direction, a moment which rotates the portable device in a first direction of rotation being generated around an axis in parallel to the front surface of the housing and perpendicular to a direction of the reciprocating motion.
A position control method, comprising:
- determining whether a portable device has fallen;
- and
- generating a moment which rotates the portable device with reciprocating motion of a movable unit in a direction in parallel to a front surface of the portable device in which an acceleration in movement in one direction is higher than an acceleration in movement in the other direction while the portable device falls.
