Abstract: Techniques and devices for seamless authentication using radar are described. In some implementations, a radar field is provided through a radar-based authentication system. The radar-based authentication system can sense reflections from an object in the radar field and analyze the reflections to determine whether the object is a person. In response to determining that the object is a person, the radar-based authentication system can sense an identifying characteristic associated with the person. Based on the identifying characteristic, the radar-based authentication system can determine that the person is an authorized user.

Abstract: A gesture component with a gesture library is described. The gesture component is configured to expose operations for execution by application of a computing device based on detected gestures. In one example, an input is detected using a three dimensional object detection system of a gesture component of the computing device. A gesture is recognized by the gesture component based on the detected input through comparison with a library of gestures maintained by the gesture component. An operation is then recognized that corresponds to the gesture by the gesture component using the library of gestures. The operation is exposed by the gesture component via an application programming interface to at least one application executed by the computing device to control performance of the operation by the at least one application.

Abstract: This document describes techniques for fine-motion virtual-reality or augmented-reality control using radar. These techniques enable small motions and displacements to be tracked, even in the millimeter or sub-millimeter scale, for user control actions even when those actions are small, fast, or obscured due to darkness or varying light. Further, these techniques enable fine resolution and real-time control, unlike conventional RF-tracking or optical-tracking techniques.

Abstract: This document describes techniques and apparatuses for connecting an electronic component to an interactive textile. Loose conductive threads of the interactive textile are collected and organized into a ribbon with a pitch that matches a corresponding pitch of connection points of the electronic component. Next, non-conductive material of the conductive threads of the ribbon are stripped to expose the conductive wires of the conductive threads. After stripping the non-conductive material from the conductive threads of the ribbon, the connection points of the electronic component are bonded to the conductive wires of the ribbon. The conductive threads proximate the ribbon are then sealed using a UV-curable or heat-curable epoxy, and the electronic component and the ribbon are encapsulated to the interactive textile with a water-resistant material, such as plastic or polymer.

Abstract: This document describes techniques using, and devices embodying, wide-field radar-based gesture recognition. These techniques and devices can enable a great breadth of gestures and uses for those gestures, such as gestures to use, control, and interact with computing and non-computing devices, from software applications to refrigerators.

Abstract: This document describes techniques and devices for radar-based gesture-recognition through a wearable device. The techniques enable an easy-to-use input interface through this wearable radar device, in contrast to small or difficult-to-use input interfaces common to wearable computing devices. Further, these techniques are not limited to interfacing with wearable computing devices, but may aid users in controlling various non-wearable devices, such as to control volume on a stereo, pause a movie playing on a television, or select a webpage on a desktop computer.

Abstract: Techniques of identifying gestures include detecting and classifying inner-wrist muscle motions at a user's wrist using micron-resolution radar sensors. For example, a user of an AR system may wear a band around their wrist. When the user makes a gesture to manipulate a virtual object in the AR system as seen in a head-mounted display (HMD), muscles and ligaments in the user's wrist make small movements on the order of 1-3 mm. The band contains a small radar device that has a transmitter and a number of receivers (e.g., three) of electromagnetic (EM) radiation on a chip (e.g., a Soli chip. This radiation reflects off the wrist muscles and ligaments and is received by the receivers on the chip in the band. The received reflected signal, or signal samples, are then sent to processing circuitry for classification to identify the wrist movement as a gesture.

Abstract: This document describes techniques for radio frequency (RF) based micro-motion tracking. These techniques enable even millimeter-scale hand motions to be tracked. To do so, radar signals are used from radar systems that, with conventional techniques, would only permit resolutions of a centimeter or more.

Abstract: This document describes techniques and devices for a radar recognition-aided search. Through use of a radar-based recognition system, gestures made by, and physiological information about, persons can be determined. In the case of physiological information, the techniques can use this information to refine a search. For example, if a person requests a search for a coffee shop, the techniques may refine the search to coffee shops in the direction that the person is walking. In the case of a gesture, the techniques may refine or base a search solely on the gesture. Thus, a search for information about a store, car, or tree can be made responsive to a gesture pointing at the store, car, or tree with or without explicit entry of a search query.
