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.

Abstract: This document describes techniques and systems for radar-based gesture-recognition with context-sensitive gating and other context-sensitive controls. Sensor data from a proximity sensor (108) and/or a movement sensor (108) produces a context of a user equipment (102). The techniques and systems enable the user equipment (102) to recognize contexts when a radar system (104) can be unreliable and should not be used for gesture-recognition, enabling the user equipment (102) to automatically disable or “gate” the output from the radar system (104) according to context. The user equipment (102) prevents the radar system (104) from transitioning to a high-power state (1910) to perform gesture-recognition in contexts where radar data detected by the radar system (104) is likely due to unintentional input. By so doing, the techniques conserve power, improve accuracy, or reduce latency relative to many common techniques and systems for radar-based gesture-recognition.

Abstract: This document describes techniques and devices for non-line-of-sight radar-based gesture recognition. Through use of the techniques and devices described herein, users may control their devices through in-the-air gestures, even when those gestures are not within line-of-sight of their device's sensors. Thus, the techniques enable users to control their devices in many situations in which control is desired but conventional techniques do permit effective control, such as to turn the temperature down in a room when the user is obscured from a thermostat's gesture sensor, turn up the volume on a media player when the user is in a different room than the media player, or pause a television program when the user's gesture is obscured by a chair, couch, or other obstruction.

Abstract: Various embodiments dynamically learn user-customizable input gestures. A user can transition a radar-based gesture detection system into a gesture-learning mode. In turn, the radar-based gesture detection system emits a radar field configured to detect a gesture new to the radar-based gesture detection system. The radar-based gesture detection system receives incoming radio frequency (RF) signals generated by the outgoing RF signal reflecting off the gesture, and analyzes the incoming RF signals to learn one or more identifying characteristics about the gesture. Upon learning the identifying characteristics, the radar-based gesture detection system reconfigures a corresponding input identification system to detect the gesture when the one or more identifying characteristics are next identified, and transitions out of the gesture-learning mode.

For instance, sensor data can be received from one or more sensors implemented with an ergonomic assessment garment worn by a user. Corporeal data associated with at least one body segment of the user can be determined based at least in part on the sensor data. The corporeal data is associated with a bend angle associated with the at least one body segment. An ergonomic assessment associated with the user can be determined based at least in part on the corporeal data. The ergonomic assessment can include an indication of one or more ergonomic zones associated with the user, the one or more ergonomic zones being determined based at least in part on the bend angle associated with the at least one body segment.

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 apparatuses and techniques for radar-enabled sensor fusion. In some aspects, a radar field is provided and reflection signals that correspond to a target in the radar field are received. The reflection signals are transformed to provide radar data, from which a radar feature indicating a physical characteristic of the target is extracted. Based on the radar features, a sensor is activated to provide supplemental sensor data associated with the physical characteristic. The radar feature is then augmented with the supplemental sensor data to enhance the radar feature, such as by increasing an accuracy or resolution of the radar feature. By so doing, performance of sensor-based applications, which rely on the enhanced radar features, can be improved.

Abstract: This document describes techniques using, and objects embodying, an interactive fabric which is configured to sense user interactions in the form of single or multi-touch-input (e.g., gestures). The interactive fabric may be integrated into a wearable interactive garment (e.g., a jacket, shirt, or pants) that is coupled (e.g., via a wired or wireless connection) to a gesture manager. The gesture manager may be implemented at the interactive garment, or remote from the interactive garment, such as at a computing device that is wirelessly paired with the interactive garment and/or at a remote cloud based service. Generally, the gesture manager recognizes user interactions to the interactive fabric, and in response, triggers various different types of functionality, such as answering a phone call, sending a text message, creating a journal entry, and so forth.

Through use of the techniques and devices described herein, users may control their devices even when a user's gesture is occluded by some material between the user's hands and the device itself. Thus, the techniques enable users to control their mobile devices in many situations in which control is desired but conventional techniques do permit effective control, such as when a user's mobile computing device is occluded by being in a purse, bag, pocket, or even in another room.

Abstract: This document describes techniques and systems that enable a mobile device-based radar system (104) for providing a multi-mode interface (114). A radar field (110) is used to enable a user device (102, 702) to accurately determine a presence or threshold movement of a user near the user device. The user device provides a multi-mode interface having at least first and second modes and providing a black display or a low-luminosity display in the first mode. The user device detects, based on radar data and during the first mode, a presence or threshold movement by the user relative to the user device and responsively changes the multi-mode interface from the first mode to the second mode. Responsive to the change to the second mode, the user device provides visual feedback corresponding to the implicit interaction by adjusting one or more display parameters of the black display or the low-luminosity display.
