1. A haptic assembly comprising:
- a glove body configured to cover a hand;
a haptic apparatus coupled to the glove body, the haptic apparatus comprising three or more plates and a malleable sheet, the malleable sheet coupled to the three or more plates and the glove body, a portion of the three or more plates to contact the hand according to a shape of the malleable sheet; and
an actuator coupled to the malleable sheet, the actuator configured to actuate, based in part on a rigidity of a virtual object, the malleable sheet to transform the shape of the malleable sheet to adjust an amount of direct contact area generated between a subportion of the three or more plates and at least a portion of the hand, wherein the haptic assembly comprises an operation mode wherein a subset of the three or more plates does not contact the portion of the hand based in part on the rigidity of the virtual object.

Abstract
Embodiments relate to a system and a method for providing haptic feedback to a user by controlling an area of a surface of a haptic assembly in touch (directly or indirectly) with a user. The haptic assembly can be actuated such that a surface area of the haptic assembly in contact with a user can be adjusted. An area of the haptic assembly in contact with a user can be changed by modifying a shape of the haptic assembly. Hence, by changing the shape of the haptic assembly, a user touching a virtual object in a virtual space with a particular rigidity can be emulated.

11. A haptic assembly comprising:
-
a haptic apparatus comprising three or more plates coupled to a malleable sheet, a portion of the three or more plates configured to contact a part of a user according to a shape of the malleable sheet; an actuator configured to generate an actuation signal to actuate, based in part on a rigidity of a virtual object, the malleable sheet to transform the shape of the malleable sheet to adjust an amount of direct contact area generated between a subportion of the three or more plates and at least a portion of the hand, wherein the haptic assembly comprises an operation mode wherein a subset of the three or more plates does not contact the portion of the hand based in part on the rigidity of the virtual object; and a tendon coupled between the malleable sheet and the actuator, the tendon to transfer the actuation signal to the malleable sheet to actuate the malleable sheet. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
