Abstract: A method described herein includes receiving an initial input of a first input modality from a user at a head-wearable device. The first input modality comprises a gaze at a real-world object. In accordance with a determination that the gaze remains at the real-world object for a threshold amount of time, the method includes generating, based on the real-world object, one or more suggested inputs of a second input modality, distinct from the first input modality, associated with an operation at the head-wearable device and outputting an indication to perform the one or more suggested inputs to cause the operation at the head-wearable device. Furthermore, in accordance with a determination that the gaze no longer remains at the real-world object, the method includes ceasing to output the indication to perform the one or more suggested inputs.

Abstract: Disclosed herein are techniques for fabricating a straight or slanted surface-relief grating with a uniform or non-uniform grating depth. According to certain embodiments, a gray-tone photoresist includes a novolac resin, a diazonaphthoquinone (DNQ) dissolution inhibitor, and one or more crosslinking agents for crosslinking the novolac resin at an elevated temperature to increase a glass transition temperature of the gray-tone photoresist and/or lower an etch rate of the gray-tone photoresist. After gray-tone photo exposure and development, the gray-tone photoresist is baked at the elevated temperature to crosslink. The crosslinked gray-tone photoresist has a higher density and a higher glass transition temperature, and thus would not become flowable to cause ripples or other surface roughness during the etching.

Abstract: An artificial reality system receives information identifying a physical object and location information describing a geographical location associated with the artificial reality system, in which the information identifying the physical object includes a trackable feature associated with the physical object. Upon receiving a request from a user to locate the physical object, the artificial reality system determines a most recent geographical location associated with the physical object based at least in part on the trackable feature and the location information. The artificial reality system then communicates a set of spatial audio cues to the user, in which the set of spatial audio cues guides the user to the most recent geographical location associated with the physical object.

Abstract: A virtual reality system including a garment worn by a user, such as a glove, includes a jamming that jams movement of a portion of the user's body by increasing a rigidity of certain portions of the garment or by preventing a certain portion of the garment from expanding past a certain length. This allows the garment to simulate the physical sensation that occurs when the user touches an object. For example, to simulate the sensation of holding a coffee mug, the jamming mechanism prevents the user's fingers from curling after the user's fingers have reached a position equivalent to making physical contact with the coffee mug.
