(a) a resultant force of the tensile forces coincides with a force generated on the object in a virtual space;
(b) a moment generated on the haptic sensation producing member by the tensile forces coincides with a moment generated on the object in the virtual space;
(c) each of the calculated tensile forces is within a range from a minimum tensile force with which the wires are not loosened to a set maximum tensile force; and
(d) a total value of the tensile forces is a lowest value in a range within which the conditions (a) to (c) are satisfied,wherein when each of the plurality of wires is pulled with a same tensile force, connection points of the plurality of wires with the haptic sensation producing member result in no movement of the haptic sensation producing member.

Abstract
A haptic sensation producing device (10) for presenting a haptic sensation to a user is equipped with a panel-like haptic sensation producing member (11) that is disposed on the front face side of a display panel (20), wires (12) for holding the haptic sensation producing member (11), wire tensile units (13) that are provided for the respective wires and pull the corresponding wires, and a control unit (14) that controls the wire tensile units (13) to move the haptic sensation producing member (11) and generate the haptic sensation. If a change occurs in an object in a content as a result of a touch by the user, the control unit (14) calculates tensile forces such that the haptic sensation conforming to the change can be generated and the tensile forces are optimized, and controls the wire tensile units (13) based on the calculated tensile forces.
