Abstract: A fluidic device comprises a channel, a gate, and one or more additional elements. The channel is configured to transport a fluid from a source to a drain. The gate includes a chamber with an adjustable volume that affects fluid flow within the channel by displacing a wall of the channel toward an opposite wall of the channel based in part on fluid pressure within the chamber exceeding a threshold pressure. A high pressure state of the gate corresponds to a first chamber size and a first flow rate of the fluid. A low pressure state of the gate corresponds to a second chamber size that is smaller than the first chamber size and a second flow rate that is greater than the first flow rate. The additional elements are configured to reduce the threshold pressure past which the chamber decreases the cross-sectional area of the channel.

Abstract: A liquid lens structure has an adjustable and continuous range of optical power. The liquid lens structure comprises a substrate layer and a deformable membrane which enclose a volume of liquid. The substrate layer is at least partially transparent in the optical band. The deformable membrane comprises a ground layer, two membrane layers, and two conductive layers. Each of the two conductive layers control electrical voltage applied to one of the membrane layers in reference to the ground layer, wherein each membrane layer deforms in response to applied electrical voltage. The deformation of the two membrane layers adjusts a curvature of the deformable membrane which provides the adjustable continuous range of optical power to the liquid lens structure.

Abstract: A wearable glove for interacting with virtual objects is described herein. An example wearable glove includes a fabric material to be worn on a user's hand. The wearable glove also includes a matrix made of an elastic polymer, the matrix including a plurality of voids, each respective void (i) including at least one fluidic actuator and (ii) not being fluidically coupled with a positionally adjacent void. The wearable glove additionally includes a non-fluidic actuator configured to restrict movement of one of the user's digits; and one or more position sensors for monitoring positional data used to a determine a position of the wearable glove within a three-dimensional space. The wearable device can control the at least one fluidic actuator and the at least one non-fluidic actuator to simulate real-world interactions in the artificial-reality environment based on the position of the wearable device as compared to respective positions of virtual objects.

Abstract: An example method of identifying a touch gesture on a user is provided. The method includes receiving, by one or more transducers of a wearable device, a set of signals that establish a signal pathway to the wearable device. The method also includes, while receiving the set of signals, determining baseline characteristics for the signal pathway, and sensing a change in the baseline characteristics caused by user interaction with an affordance of a user interface projected or perceived on the user's appendage. The method further includes, in accordance with a determination that the sensed change in the baseline characteristics satisfies a contact criterion, reporting a candidate touch event on the user's appendage to a separate electronic device that creates the user interface or is in communication with another electronic device that creates the user interface.

Abstract: A virtual reality system enables a user to interact with virtual objects. The system includes a fiducial ring, an imaging device and a console. The fiducial ring includes a ring body that includes a plurality of fiducial markers that each correspond to a different location on the ring body. An imaging device is configured to capture one or more images of the fiducial ring. The console receives the images that include an image of one or more fiducial markers. Based on the received images of the fiducial markers, the console determines a location on the fiducial ring that corresponds to the imaged fiducial marker. The console determines a position of the fiducial ring based on the determined location of the fiducial marker on the fiducial ring. The console provides content to a head mounted display (HMD) based on the determined position of the fiducial ring.
