  • Publication number: 20240103705
    Abstract: Various implementations disclosed herein facilitate interactions with a user interface in 3D environment in which a user interface element is moved based on a user movement in a way that the user interface element appears to lag behind or follow a portion of the user (e.g., the user's fingertip). The user interface element may be moved in a way that it converges with and thus catches up to the portion of the user. Such convergence may be based on the speed of the movement of the portion of the user. No convergence may occur when the portion of the user is not moving or is moving below a threshold speed. When the portion of the user is moving (e.g., above a threshold speed), the user interface component may converge with the portion of the user and the rate of convergence may be increased with faster speeds.

  • Publication number: 20240103635
    Abstract: Suppressing a hand gesture upon detecting peripheral events on a peripheral device includes determining a first hand pose for a first hand a second hand pose for a second hand in response to a detected peripheral device peripheral event, determining, based on the first hand pose and the second hand pose, at least one hand of the first hand and the second hand in a peripheral use mode, detecting an input gesture from a hand of the at least one hand determined to be in the peripheral use mode, and rejecting the input gesture by a user input pipeline in accordance with the determination that the hand is in the peripheral use mode. The presence of a peripheral device is confirmed by activating a computer vision system in response to determining that a peripheral use condition is satisfied.

  • Publication number: 20240094882
    Abstract: In some embodiments, a computer system facilitates user input for displaying a selection refinement user interface object in an object within a three-dimensional environment, wherein the selection refinement user interface object indicates a location in the object at which the computer system performs a selection operation in response to further user input. In some embodiments, a computer system facilitates user input for activating a selection refinement mode in the three-dimensional environment during which an interaction point for a selection operation is movable based on movement of a hand of the user of the computer system.

  • Patent number: 11728398
    Abstract: Semiconductor devices having conductive floating gates superimposed on and/or embedded within a conducting channel for managing electromagnetic radiation in the device. The conductive floating gates can comprise a one- or two-dimensional array of asymmetric structures superimposed on and/or embedded within the conducting channel. The conductive floating gates can comprise Nb2N, Ta2N, TaNx, NbNx, WNx, or MoNx or any transition metal nitride compound. The device can include a plurality of conductive floating gates on a rear surface of a barrier layer, wherein each of the conductive floating gates might be separately biased for individual tuning. Antennas for capturing or emitting THz or sub-THz radiation could be attached to the device contacts. Terahertz or infrared radiation could be manipulated by driving a current through the conducting channel into a plasmonic boom regime. Additional manipulation of the electromagnetic radiation could be achieved by having antennas with an appropriate phase angle shift.

  • Publication number: 20230225060
    Abstract: A conductive solder pad for a ball grid array (BGA) includes a concave edge to accommodate a via that exits a substrate at a position at the surface of the substrate that is offset from the solder pad. The offset arrangement of the via and solder pad allow for differential thermal expansion of the substrate material and the via material with reduced risk of cracking or fracturing the solder joint. The concave edge of the solder pad provides a gap from the via to avoid unintended electrical connections while maintaining the solder-joint pitch of the BGA.
