  • Patent number: 10293249
    Abstract: 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.

  • Patent number: 10223879
    Abstract: A haptic system includes a structure having a conductive layer and a reactive layer. The conductive layer is coupled to a power source and the reactive layer is coupled to a switch having a first state and a second state. The power source enables the conductive layer to generate a charge. The first state of the switch operates the reactive layer to block the establishment of a tissue-stimulating electric field. The second state of the switch operates the reactive layer to enable the establishment of a tissue-stimulating electric field to generate a touchless haptic effect.

    Abstract: In one example, hollow tubes each having a spherical mass inside are positioned between two plates. Each plate can have a matrix of nodes that mirrors the other plate. If the mass is a ferromagnetic mass, then each node can have an electromagnetic coil such that the ferromagnetic mass. If the mass is a conductive mass, then each node can be a conductive node. The conductive nodes can have the same type of charge or opposing charges. The conductive mass can be negatively charged, positively charged, or part can be positively charged and part negatively charged. Spring(s) can be between the mass and the first plate or between the mass and the second plate, or both. Electric current(s) can be applied to a node in the first plate, a node in the second plate, or both, which causes the mass to shift to output a haptic effect.
