Tactile force sense presentation device, information terminal, tactile force sense presentation method, and computer readable recording medium

摘要

Provided are a tactile force presentation device, an information terminal, a tactile force presentation method, and a program that make it possible to present three-dimensional tactile force across a wide range while achieving a reduction in device size. The information terminal is provided with: a display device; a position detection unit that detects the position of a part of a user that is to be presented with tactile force; an information processing unit that alters content in accordance with a detected position and calculates the amount of tactile force to be presented on the basis of the altered content; and a tactile force presentation device. The tactile force presentation device is provided with: a transmission member that extends to the part of the user that is to be presented with tactile force and transmits tensile force; a drive unit that generates tensile force and provides the tensile force to the transmission member; and a control unit that causes tensile force to be generated as initial force in the drive unit in advance and increases or decreases the initial force when the calculated tactile force is presented so that the tactile force is provided to the user via the transmission member.
