  • Publication number: 20240103640
    Abstract: Embodiments are directed to a low profile key for a keyboard having an overmolded support structure. In one aspect, an embodiment includes a key cap having an illuminable symbol. A support structure having a pair of overmolded wings may pivotally couple to the key cap. A switch housing may surround the support structure and connect each of the first and second wings. A tactile dome may be at least partially positioned within the switch housing and configured to bias the key cap upward. A sensing membrane may be positioned along an underside surface of the tactile dome and configured to trigger a switch event in response to a collapsing of the tactile dome caused by a depression of the key cap. A feature plate may be positioned below the sensing membrane. A light guide panel may define at least one light extraction feature that may be configured to propagate light toward the key cap and cause illumination of the illuminable symbol.

  • Patent number: 11914780
    Abstract: A finger-mounted device may include finger-mounted units. The finger-mounted units may each have a body that serves as a support structure for components such as force sensors, accelerometers, and other sensors and for haptic output devices. The body may have sidewall portions coupled by a portion that rests adjacent to a user's fingernail. The body may be formed from deformable material such as metal or may be formed from adjustable structures such as sliding body portions that are coupled to each other using magnetic attraction, springs, or other structures. The body of each finger-mounted unit may have a U-shaped cross-sectional profile that leaves the finger pad of each finger exposed when the body is coupled to a fingertip of a user's finger. Control circuitry may gather finger press input, lateral finger movement input, and finger tap input using the sensors and may provide haptic output using the haptic output device.

  • Patent number: 11714495
    Abstract: A finger device may be worn on a user's finger and may serve as a controller for a head-mounted device or other electronic device. The finger device may have a housing having an upper housing portion that extends across a top of the finger and first and second side housing portions that extend down respective first and second sides of the finger. Sensors in the side housing portions may measure movements of the sides of the finger as the finger contacts an external surface. To ensure that the sensors are appropriately positioned relative to the sides of the finger, the housing may include one or more adjustable structures such as an elastomeric band, a drawstring, a ratchet mechanism, a scissor mechanism, and/or other adjustable structures for adjusting the position of the first and second side housing portions and associated sensors relative to the upper housing portion.

  • Publication number: 20230004231
    Abstract: A system may include one or more finger-mounted devices such as finger devices with U-shaped housings configured to be mounted on a user's fingers while gathering sensor input and supplying haptic output. The sensors may include strain gauge circuitry mounted on elongated arms of the housing. When the arms move due to finger forces, the strain gauge circuitry can measure the arm movement. The sensors may also include ultrasonic sensors. An ultrasonic sensor may have an ultrasonic signal emitter and a corresponding ultrasonic signal detector configured to detect the ultrasonic signals after passing through a user's finger. A two-dimensional ultrasonic sensor may capture ultrasonic images of a user's finger pad. Ultrasonic proximity sensors may be used to measure distances between finger devices and external surfaces. Optical sensors and other sensors may also be used in the finger devices.

  • Patent number: 11513611
    Abstract: An interface device includes a movable button connected to a frame structure by resilient structures positioned laterally between the button and the frame structure. Multiple layers or diaphragms of material can be used to make the button, frame, and resilient structures. Movement of the button can trigger a switch or sensor in a manner allowing an electronic device to detect interaction with the button. The interface device can be implemented in an electronic device such as a keyboard that has a low number of parts yet also providing tactile, stabilized key travel, support for various sensor or switch types for the keys, and, in some cases, haptic feedback.
