Abstract

A pseudo force sense generation apparatus including a base, and first to nth vibrators that make asymmetrical motions where relative positions of the vibrators to the base are fixed is provided. An ith vibrator included in the first to the nth vibrators is each capable of presenting pseudo force sense in an ith straight-line direction. The pseudo force sense generation apparatus makes a rotary motion centered at a neighborhood of a center of gravity of a system by driving of the vibrators.

First claim

What is claimed is:

1. A pseudo force sense generation apparatus comprising:
a base;
first to nth vibrators that make asymmetrical motions where relative positions of the vibrators to the base are fixed; and
an electronic device having a fixed relative position to the base, wherein
an ith vibrator included in the first to the nth vibrators is each capable of presenting pseudo force sense in an ith straight-line direction, where n is an integer of two or more, and i=1, . . . n,
the ith straight-line direction is a straight-line direction along one of sides of a virtual polygon having three or more sides on a same plane,
the electronic device is arranged in a neighborhood of a center of gravity of a system which corresponds to a region surrounded by the first to the nth vibrators and that is away from the center of gravity at a distance equal to or less than a predetermined value,
mass per unit volume of the electronic device is greater than mass per unit volume of the base,
a weight distribution of the system is biased toward the neighborhood of the center of gravity of the system, and
the pseudo force sense generation apparatus makes a rotary motion centered at the neighborhood of the center of the gravity by driving of the vibrators.

2. The pseudo force sense generation apparatus according to claim 1 , wherein a rotary motion energy of the pseudo force sense generation apparatus required for presenting rotational force sense by driving of the vibrators is smaller than a translational motion energy of the pseudo force sense generation apparatus required fori presenting translational force sense by driving of the vibrators.

3. The pseudo force sense generation apparatus according to claim 1 , wherein
the base has a rotationally symmetrical structure, and
the vibrators are arranged in rotational symmetry to a rotation center of the rotary motion.

4. The pseudo force sense generation apparatus according to claim 1 , wherein
the system includes the first to the nth vibrators.

5. The pseudo force sense generation apparatus according to claim 1 , wherein the neighborhood of the center of gravity includes at least a power supply unit of the electronic device.
