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.

A pseudo force sense generation apparatus comprising:
- a base mechanism;
- and
- a contact mechanism that performs periodical asymmetric translational motion relative to the base mechanism and gives force based on the asymmetric translational motion to a user with which the contact mechanism is in direct or indirect contact, wherein
- 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 mass of a system supporting the contact mechanism where the system has the base mechanism and a mechanism that is attached to the base mechanism,
- the base mechanism includes a base mechanism-side component,
- the contact mechanism includes a contact mechanism-side component that performs asymmetric translational vibration relative to the base mechanism-side component and a contact portion which is at least partially positioned outside the contact mechanism-side component and performs asymmetric translational motion based on the asymmetric translational vibration of the contact mechanism-side component, wherein the asymmetric translational vibration is performed such that a force given by the contact mechanism to the user is in a predetermined direction and has an absolute value higher than a force that is in the opposite direction to the predetermined direction,
- among components of the base mechanism and the contact mechanism, only the contact portion performing the asymmetric translational motion relative to the base mechanism-side component is a part that makes direct or indirect contact with the user, and
- the pseudo force sense generation apparatus presents force sense to the user by the asymmetric translational motion of the contact portion relative to the base mechanism-side component in a condition that the user supports reaction force of weight of the pseudo force sense generation apparatus via only the contact portion performing the asymmetric translational motion relative to the base mechanism-side component, wherein directions of the asymmetric translational motion of the contact portion relative to the base mechanism-side component contain directional components parallel to surface of the contact portion where the user supports reaction force of weight of the pseudo force sense generation apparatus,
- the contact portion is a case that covers at least part of an external area of a mobile terminal device included in a body portion supporting the base mechanism-side component thereon, and
- the body portion is a mechanism included in the base mechanism or the mechanism that is attached to the base mechanism.
