Abstract: A user interface system enables communication through inaudible speech by detecting physiological signals associated with inner voice communication. The system includes a wearable device positioned in, on, or around a user's ear, housing one or more sensor modalities such as electromyography (EMG) sensors for detecting muscle movements, functional near-infrared spectroscopy (fNIR) sensors for brain activity, and/or detection-and-ranging systems using sonar or radar for micro-deformations. Pre-processing modules condition the sensor data, which is then analyzed by one or more machine learning models to reconstruct the content of the user's inaudible communication and produce output representations. The system enables high-bandwidth natural language interaction without audible vocalization, maintaining privacy while supporting applications including AI assistant interaction, real-time translation, secure authentication, and inter-party communication.

Abstract: This disclosure describes, in part, systems and methods that enable users to manage, search for, share and discover objects based on a context of the object from the user's perspective. The same object may have vastly different meanings (context) to different individuals based on how they experience the object. Rather than managing objects solely based on information about the object, the implementations described allow users to specify a context for the object and manage objects based on that context. In addition, external sources may provide supplemental information about objects and/or representations of objects.

Abstract: Described are systems and methods that facilitate visual search for and price filtering of information. For example, rather than requiring a user to select a pre-defined price range (e.g., “under $25,” $25 to $50,” “$50 to $100”) for filtering, a user may price filter search results by specifying a single price filtering value around which the search results are filtered. The range around the single price filtering value is dynamically selected based on, for example, the search results being filtered, the past purchase history of the user, past user search history, etc.

Abstract: In one embodiment, a geo-social networking system receives from a first user's location a message identifying the first user and one or more other users, generating a redeemable certificate including pictures of the first user and the one or more other users, and present the redeemable certificate to the first user.
