    Abstract: A method of creating haptic stimulations and anatomical information includes a wearable device including a plurality of transducers that can each generate one or more waves. The method includes activating one or more first transducers of the plurality of transducers based on an instruction received from a remote device. Waves generated by the activated one or more first transducers provide a haptic stimulation. The method further includes activating one or more second transducers of the plurality of transducers. Waves generated by the activated one or more second transducers provide anatomical information of a user of the wearable device when the waves are received by one or more transducers of the plurality of transducers.

    Abstract: A sensor records information about skin stretch perceived by a user based on an interaction with a real object. The sensor includes a mechanical housing configured to be worn on a finger of a user, and a mechanism coupled to the mechanical housing. The mechanism includes a first bearing that rotates in a first direction in response to an interaction with a surface. The mechanism also includes a second bearing coupled to the first bearing, such that rotation of the first bearing causes the second bearing to rotate in a direction opposite to the first direction. The second bearing is in contact with a portion of the finger, and includes a feedback surface that simulates a force associated with the interaction with the surface. The sensor includes a controller configured to monitor rotation of the second bearing and record skin stretch information responsive to the interaction with the surface.

    Abstract: A fluidic device controls fluid flow in a channel conduit from a fluid entrance to a fluid exit. In some embodiments, the fluidic device comprises the channel conduit, a flexible element, a cross member, and a gate. The channel conduit is bounded by an inner surface that includes a protrusion. The flexible element is coupled to the inner surface of the channel conduit on a different side of the inner surface as the protrusion. The cross member has a first end that is coupled to a deformable surface that is part of the inner surface of the channel conduit and a second end that is coupled to the flexible element. The gate is configured to deform the deformable surface in accordance with a fluid pressure at the gate. An amount of deformation imparted by the gate controls a position of the flexible element via the cross member.

    Abstract: A strain measurement ring measures strain information describing deformation of a strain-sensitive element included in the strain measurement ring due to movement of a user's finger. The strain measurement ring includes a semi-rigid band coupled to a deformable band, which together encompass a portion of the user's body. The semi-rigid band includes two coupling ends each coupled to a respective coupling end of the deformable band. The deformable band includes the strain-sensitive element. The strain measurement ring may include an emitter to transmit strain information to a virtual reality/augmented reality (VR/AR) console. The strain measurement ring may include an actuator to change the tension of the deformable band in response to haptic command signals from a VR/AR console. As a result, the strain measurement ring may apply pressure to the user's skin to simulate contact with a virtual object.

    Abstract: A haptic glove comprises a glove body including a glove digit corresponding to a phalange of a user hand with the glove digit having a bend location that is located along the glove digit. A haptic apparatus is coupled to the glove body at the bend location with the haptic apparatus comprising a plurality of sheets that are flexible and inextensible and a pressure actuator coupled to one or more of the plurality of sheets. The plurality of sheets are stacked and configured to translate relative to each other along the centerline with bending of the glove digit. The pressure actuator is configured to adjust an applied pressure to the plurality of sheets to adjust friction between the sheets. The adjustment of friction is proportional to a bending resistance of the glove digit.

    Abstract: The disclosed computer-implemented method may include (1) presenting, using a vibrotactile stimulator and a visual display, an artificial environment to a user, (2) determining whether a virtual contact is being initiated between a virtual object in the artificial environment and a surface location of the user served by the vibrotactile stimulator, and (3) actuating, in response to determining that a virtual contact is being initiated between the virtual object and the surface location, the vibrotactile stimulator to generate a vibrotactile signal to simulate initiation of the virtual contact at the surface location, where (a) the vibrotactile signal includes a magnitude-varying signal, and (b) at least one parameter of the magnitude-varying signal is based on a simulated rigidity of the virtual object as presented by the visual display. Various other methods, systems, and computer-readable media are also disclosed.
