    Abstract: A system may include one or more finger devices that gather input from a user's fingers. The system may include control circuitry that sends control signals to an electronic device based on the input gathered with the finger devices. A finger device may include one or more proximity sensors that measure a distance to the user's finger. The proximity sensor may be a self-mixing optical proximity sensor having a laser and photodiode. The proximity sensor may have submicron resolution and may be configured to detect very small movements of the finger as finger pad is moved around by a thumb finger, by a surface, and/or by other finger movements. The proximity sensor may measure changes in distance between the proximity sensor and a flexible membrane that rests against a side portion of the user's finger.

    Abstract: Self-mixing interferometry (SMI) sensors can be used for generation of content using an input device without requiring a touch-sensitive surface. In some examples, the SMI sensors can be used to detect characteristics of the input device including position, orientation, and/or motion of the input device and/or force applied by the input device (e.g., force applied by a stylus tip). In some examples, some or all of the characteristics of the input device can be used in processing to generate content, including textual character input and three-dimensional objects. In some examples, the generation of content can use information from one or more additional sensors for the input device and/or from additional devices in combination with the characteristics of the input device based on the SMI sensors for generation of content.

    Abstract: An input device includes an enclosure defining a three-dimensional input space and one or more self-mixing interferometry sensors coupled to the enclosure and configured to produce a self-mixing interferometry signal resulting from reflection of backscatter of emitted light by a body part in the three-dimensional input space. In various examples, movement of the body part may be determined using the self-mixing interferometry signal, which may in turn be used to determine an input. In some examples, a body part displacement or a body part speed and an absolute distance to the body part may be determined using the self-mixing interferometry signal and used to determine an input. In a number of examples, multiple self-mixing interferometry sensors may be used and the movement may be determined by analyzing differences between the respective produced self-mixing interferometry signals.

    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.
