Abstract: Systems and methods of controlling activation of different input elements using an actuator are disclosed herein. An example method includes in response to determining that a representation of a user's finger is located within a predefined distance of an input element: obtaining information regarding an amount of force needed to actuate the input element, and causing adjustment of a physical characteristic of an actuator while the actuator is associated with the input element. The method further includes, in response to an input having at least the amount of force applied by the user's finger to a component of the actuator while the actuator is associated with the input element, causing an input command to be performed and providing a haptic response via the actuator component.

Abstract: Systems and methods of controlling activation of different input elements using an actuator are disclosed herein. An example method includes in response to detecting that a representation of a finger is located by a first input element: obtaining information regarding a first amount of force to actuate the first input element, and causing adjustment of a physical characteristic of an actuator so that a first amount of force directed to a component of the actuator activates the first input element. In response to detecting that the representation of the finger is located by a second input element, the method also includes: obtaining information regarding a second amount of force distinct from the first amount of force, and causing adjustment of the physical characteristic of the actuator so that the second amount of force directed to the component of the actuator activates the second input element.

Abstract: A head mounted display (HMD) includes a set of one or more lenses defining an optical axis, a display configured to project light through the set of the one or more lenses, a voice coil actuator coupled with the display and configured to move the display along the optical axis, and a first guide that is separate from the first voice coil actuator and coupled with the first display to guide the movement of the first display. The HMD additionally includes a set of one or more position sensors configured to determine a position of the display long the optical axis and an electronic controller configured to receive information identifying a reference position of the display along the optical axis and generate one or more electrical signals for initiating a movement of the first display toward the first reference point along the optical axis.

Abstract: An apparatus for fixing a wearable structure and/or a user-feedback element to a user is provided. The apparatus includes a wearable structure configured to be worn by a user, and a grounding assembly, coupled to the wearable structure. The grounding assembly includes: (i) an inflatable bladder, coupled to a first portion of the wearable structure, and (ii) a cord, coupled to a second portion of the wearable structure and the inflatable bladder. The inflatable bladder is configured to receive a fluid from a source. The cord is configured to tighten around a portion of the user's body according to and in proportion with the fluid pressure inside the inflatable bladder.

Abstract: A method generates synchronized auditory and haptic feedback for artificial-reality environments. The method includes performing a simulation of a user interaction with a virtual object in an artificial-reality environment. The user interaction (i) traverses a surface of the virtual object (e.g., running a finger over a textured surface), and (ii) includes a set of contact events (e.g., a sparse set of events). The method also includes estimating a trajectory of the user interaction with the virtual object based on the set of contact events. The method also includes determining a surface profile associated with the surface of the virtual object, generating an excitation force profile according to (i) the estimated trajectory and (ii) the surface profile, and rendering, based on the excitation force profile, audio and synchronized haptic feedback for the user interaction.
