    Abstract: A head-mounted display may include a display system and a lens system in a housing. The head-mounted display may include control circuitry that operates the head-mounted display in an active use mode and a protected mode. In the protected mode, the display system may be protected from collisions with the lens system. Placing the head-mounted display in the protected mode may include using an actuator to increase the distance between the display system and the lens system, may include injecting fluid between the display system and the lens system, and/or may include deploying a protective layer between the display system and the lens system. The control circuitry may determine whether to operate the head-mounted display in protected mode or active use mode based on sensor data, on/off status information, location information, and/or other information.

    Abstract: A head-mounted device may have a display with first and second pixel arrays that display content for a user. A head-mounted support structure in the device supports the pixel arrays on the head of the user. A left positioner may be used to position a left lens module that includes a left lens and the first pixel array. A right positioner may be used to position a right lens module that includes a right lens and the second pixel array. Sensing circuitry such as proximity sensing circuitry may be used to detect relative positions between the left and right lens modules and facing surfaces of a user's nose while the user is wearing the head-mounted support structure. Control circuitry may adjust the positions of the left and right lens modules using interpupillary distance information for the user and using information from the sensing circuitry.

    Abstract: A display system includes a controller and a head-mounted display. The head-mounted display includes a display, a head support coupled to the display for supporting the display on a head of a user to be viewed by the user, and sensors coupled to the head support for sensing an environment from the head-mounted display unit in low light. The sensors include one or more of an infrared sensor for sensing the environment with infrared electromagnetic radiation, or a depth sensor for sensing distances to objects of the environment, and also include an ultrasonic sensor for sensing the environment with ultrasonic sound waves. The controller determines graphical content according to the sensing of the environment with the one or more of the infrared sensor or the depth sensor and with the ultrasonic sensor, and operates the display to provide the graphical content concurrent with the sensing of the environment.

    Abstract: A wristband can comfortably secure an electronic device, such as a wristwatch or fitness/health tracking device, to a wrist of a user. The wristband can include a number of magnets that allow the wristband to be magnetically coupled to itself when folded over or when separate band portions are overlapping. The magnets can include a polymer mixed with a magnetic material to provide magnetic properties and flexibility. The magnets can be joined together by a continuous support structure that extends through opposing pairs of the magnets. The support structure can provide substantial and ability as well as tensile strength. The magnets and the support structure can be surrounded by a flexible cover to protect the components within.

    Abstract: An external device, such as a head-mountable device, can be operated with a ring input device worn on a finger of a user. Such devices can be operated to provide inputs that are received and acted upon by the external device. The inputs can be provided as rotating, tilting, and/or sliding at least a portion of the ring input device with another finger of the user. The ring input device can provide feedback to the user as confirmation that the inputs are being received. A feedback system can also be operated to limit or otherwise provide a force on the finger and/or another portion of the hand to simulate sensations perceived by the user.

    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.

    Abstract: A wearable electronic device including a housing that is worn by a user and a SMI sensor contained within the housing. The SMI sensor may include an emitter that outputs coherent light toward the skin of a user when the housing is worn by the user. The SMI sensor may also include a detector that detects a portion of the coherent light reflected towards the sensor and generates electrical signals that indicate displacements of the skin based on the portion of coherent light received at the detector. The housing may include a transmitter that is operatively coupled with the SMI sensor and is configured to transmit physiological data to a receiving device based on electrical signals output from the SMI sensor.
