Abstract: The present disclosure includes a finger exoskeleton including a plurality of joints and a plurality of sensors configured to measure rotation of at least some of the plurality of joints of the finger exoskeleton. The finger exoskeleton also includes a series elastic actuator comprising a spring element, the series elastic actuator configured to rotate at least one of the plurality of joints. The finger exoskeleton also includes a computing device configured to control operation of the series elastic actuator based on a torque of the at least one of the plurality of joints, the torque determined at least based on the spring element and rotation of the at least one of the plurality of joints. The present disclosure also includes associated methods and hand exoskeletons.

Abstract: A wearable device for providing haptic stimulations is provided. The wearable device includes: (i) a wearable structure attachable to a portion of a user's body; (ii) a plurality of bladders, integrated with the wearable structure, configured to expand and contract according to fluid pressure within each bladder, where each bladder of the plurality of bladders delivers a haptic stimulation to the user wearing the wearable structure when the bladder expands a threshold amount; and (iii) at least one conduit configured to transport a fluid from a fluid source to one or more bladders of the plurality of bladders, where the fluid from the fluid source increases the fluid pressure within at least the one or more bladders. The haptic stimulation experienced by the user can correspond to media presented to the user by an artificial-reality system.

Abstract: A haptic device is provided that includes a jamming assembly, anchored to the back of a user's hand, having (i) a jamming lever, (ii) an actuator to move the jamming lever from a first position to a second position different from the first position, and (iii) a slidable member configured to move back and forth in response to movement of a first of the user's fingers. The haptic device also includes an elongated element with opposing first and second end portions, where (i) the first end portion is anchored to a predefined portion of the user's first finger, and (ii) the second end portion is attached to an end portion of the slidable member. The jamming lever, when moved to the second position by the actuator, engages with a portion of the slidable member to prevent movement of the member, the elongated element, and the user's finger in a direction.

Abstract: A system or method may be provided to facilitate automatic user authentication for electronic transactions. In particular, the system or method may automatically authenticate a customer such that the customer may make complete hands free payments without the intervention of the customer or the merchant. The automatic authentication may include a check-in process and a payment authentication process. When a customer enters a designated area of a merchant, a BLE beacon device of the merchant may automatically check in the customer at the designated area of the merchant. After the customer is checked in at the merchant's designated area, the merchant may identify the customer who is about to make a payment from a plurality of other customers who also are checked in at the merchant via Bluetooth proximity and facial recognition in parallel. Thus, the customer may automatically be authenticated to make payments by facial recognition or Bluetooth proximity.

Abstract: A system or method is provided to facilitate a payment transaction by utilizing facial recognition to identify the payee of the payment transaction. In particular, the system may remember a particular list of individuals to which a user has been or are frequently making payments. The facial profiles of the individuals in the particular list may be stored and referenced for identification. When the user is ready to transfer money to any of the frequent payees, the user may use any of the payee's pictures locally, anywhere on social platforms, or just by clicking the person. After the image is selected for payment, the system may analyze the image to match the image with existing face profiles of respective frequent payees. Once the payee is identified, the system may process the payment to the identified payee.
