HAPTIC PERIPHERAL HAVING A DEFORMABLE SUBSTRATE CONFIGURED FOR AMPLIFIED DEFORMATION

摘要

A haptic peripheral includes a housing, a deformable substrate coupled to the housing to be moveable thereto, and a smart material actuator coupled to a surface of the deformable substrate. The smart material actuator produces a force that deforms the deformable substrate relative to the housing in response to the control signal from a processor to thereby provide a haptic effect to a user of the haptic peripheral. The deformable substrate includes at least one user contact portion configured to contact the user and two opposing hinges. The deformable substrate also includes at least two stiff arms, each stiff arm extending between the user contact portion and one of the two opposing hinges. The stiff arms are relatively stiffer than the user contact portion and the hinges such that the deformable substrate is configured to increase the deformation of the deformable substrate relative to the housing.
