## 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.
