Abstract: The present invention provides a pseudo-force sense to the user without requiring the user holding onto an apparatus. The pseudo-force sense generation apparatus includes: a first contact member and a second contact member that are disposed along an outer peripheral surface of a mounting region, which is a three-dimensional region occupied by a body of the user; a joining member that joins the first contact member to the second contact member; and a vibration element that performs cyclic first asymmetric vibration along a line passing through a virtual point in the mounting region and the first contact member, and transfers a force in a direction along the line based on the first asymmetric vibration to the first contact member. The virtual point is disposed between the first contact member and the second contact member, and the is also transferred to the second contact member via the joining member.

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.

Abstract: For efficient presentation of pseudo force sense, a pseudo force sense generation apparatus includes: a base mechanism; and a contact mechanism that performs periodical asymmetric motion relative to the base mechanism and gives force based on the asymmetric motion to skin or mucous membrane with which the contact mechanism is in direct or indirect contact. A mass of the contact mechanism is smaller than a mass of the base mechanism, or the mass of the contact mechanism is smaller than a sum of the mass of the base mechanism and a mass of a mechanism that is attached to the base mechanism.
