    Abstract: Disclosed herein are wearable devices, their configurations, and methods of operation that use self-mixing interferometry signals of a self-mixing interferometry sensor to recognize user inputs. The user inputs may include voiced commands or silent gesture commands. The devices may be wearable on the user's head, with the self-mixing interferometry sensor configured to direct a beam of light toward a location on the user's head. Skin deformations or vibrations at the location may be caused by the user's speech or the user's silent gestures and recognized using the self-mixing interferometry signal. The self-mixing interferometry signals may be used for bioauthentication and/or audio conditioning of received sound or voice inputs to a microphone.

    Abstract: Disclosed herein are structures, devices, and systems for detecting touch and force inputs at multiple sensing locations on a surface of an electronic device using waveguide-based interferometry. A laser light source, such as a VCSEL, inserts light into a waveguide positioned adjacent to the sensing locations, and an input at a sensing location alters the inserted light in the waveguide allowing for determination of the input's touch or force at the sensing location. Wavelength modulation of the inserted light allows isolation in frequency of the signals from each sensing location. Optical phase locking can be used to lock an absolute distance beat frequency corresponding to a stationary reference point in the waveguide.

    Abstract: A watch body includes a housing at least partially defining an interior of the watch body. A retaining feature is formed in or extends from the housing. A watch crown is retained by the retaining feature and is operable to be rotated by a user. The watch crown has a surface facing the housing. The watch crown is entirely external to the interior of the watch body. An electromagnetic radiation source is disposed within the housing and is operable to emit a beam of electromagnetic radiation toward the surface. A sensor is disposed within the housing and is operable to characterize a movement of the watch crown based at least in part on a portion of the beam of electromagnetic radiation that impinges on the surface and is redirected by the surface.

    Abstract: An optical module includes a beam-tilting light source enclosure. The enclosure is coupled to a substrate that includes a light emitter connected thereto. The enclosure has a geometry such that the enclosure has a first surface configured to couple substantially flat to the substrate and a second surface tilted with respect to the first surface and configured to couple substantially flat to a component of an electronic device through which the light is to project. The enclosure is optically transmissive and covers the light source when coupled to the substrate. In this way, the enclosure may be assembled and used in the electronic device by coupling the first surface to the substrate and coupling the second surface to the component.
