Abstract: The disclosed radar system may include a radar mechanism comprising a transmitter and at least one receiver. The radar system may also include a signal generator that generates a frequency-modulated radar signal. In addition, the radar system may include at least one frequency multiplier that, after multiplying a frequency of the frequency-modulated radar signal by a certain factor, synchronously passes the frequency-modulated radar signal to (1) the transmitter to be transmitted to at least one transponder located on a wearable device and (2) a processing device communicatively coupled to the receiver. The processing device may (1) detect a signal returned to the receiver from the transponder in response to the frequency-modulated radar signal and (2) calculate a distance between the transponder and the receiver based at least in part on an analysis of the signal returned from the transponder and the frequency-modulated radar signal received from the frequency multiplier.

Abstract: A radar system may include (1) a wearable device, (2) a set of radar devices secured to the wearable device, wherein the set of radar devices (A) transmit radar signals to at least one transponder and (B) receive the radar signals, (3) an error-mitigation device secured to the wearable device, wherein the error-mitigation device provides data for mitigating position errors in triangulation calculations involving the radar signals, and (4) at least one processing device communicatively coupled to the set of radar devices and the error-mitigation device, wherein the processing device (A) calculates, based at least in part on roundtrip flight times of the radar signals and the data, distances between the set of radar devices and the transponder and (B) triangulates, based at least in part on the distances, a three-dimensional location of the transponder relative to the wearable device. Various other apparatuses, systems, and methods are also disclosed.

Abstract: The disclosed radar system may include a radar mechanism comprising a transmitter and at least one receiver. The radar system may also include a signal generator that generates a frequency-modulated radar signal. In addition, the radar system may include a delay mechanism that (1) receives the frequency-modulated radar signal from the signal generator and (2) after a certain period of delay, passes the frequency-modulated radar signal to the transmitter to be transmitted to a transponder located on a wearable artificial reality device. The radar system may also include a processing device that (1) receives the frequency-modulated radar signal from the signal generator, (2) detects a signal returned to the receiver from the transponder, and (3) calculates a distance between the transponder and the receiver based at least in part on an analysis of the signal returned from the transponder and the frequency-modulated radar signal received from the signal generator.

Abstract: A system includes a locatable glove and a pose determination device. The locatable glove includes a glove body worn over a hand of a user, and a plurality of positioning transponders. The positioning transponders are coupled to the glove body at various positions on the glove body, and each re-radiates a received signal, the re-radiated signal unique to the positioning transponder. The pose determination device includes a plurality of antennas and a controller. The antennas are each configured to receive the unique signals re-radiated by the positioning transponders. The antennas are physically separated from each other. The controller is communicatively coupled to the plurality of antennas, and is configured to determine, for each of the received unique signals, a location of the position on the locatable glove of the positioning transponder corresponding to the unique signal.

Abstract: A haptic device provides haptic sensation to a user. The haptic device comprises a haptic plate and a plurality of actuators. The haptic plate includes a center portion and an outer portion that circumscribes the center portion. The plurality of actuators is coupled to the outer portion of the haptic plate. Of the plurality of actuators, one or more actuators are configured to generate, in accordance with haptic instructions, a haptic wave that converges to a specific waveform at a specific region of the center portion of the haptic plate. The shape of the specific waveform and the location of the specific region on the center portion of the haptic plate are based in part on the haptic instructions.
