    Abstract: This document describes techniques and systems that enable a mobile device-based radar system for applying different power modes to a multi-mode interface. The techniques and systems include a user device having a radar system, and an interaction manager. The radar system generates a radar field, provides radar data, and operates at one of various different radar-power states. The user device analyzes the radar data to detect a presence or movement of a user within the radar field. Responsive to the detection, the radar system changes from a first radar-power state to a second radar-power state. Based on this change, the interaction manager selects a power mode, for a multi-mode interface, that corresponds to the second radar-power state, and applies the selected power mode to the multi-mode interface to provide a corresponding display via a display device.

    Abstract: A removable electronics device and related pre-fabricated sensor assemblies having different sensor layouts are provided. The removable electronics module includes one or more processors, an inertial measurement unit, a first communication interface configured to communicatively couple the removable electronics device to one or more computing devices, a second communication interface configured to communicatively couple the removable electronics device to a plurality of pre-fabricated sensor assemblies, and a housing at least partially enclosing the processor, the inertial measurement unit, the first communication interface, and the second communication interface. The housing includes a first opening in at least one longitudinal surface and adjacent to at least a portion of the first communication interface and a plurality of second openings in a lower surface and adjacent to the plurality of contact pads of the second communication interface.

    Abstract: Gesture detection and interaction techniques are described. Object detection used to support the gestures may be accomplished in a variety of ways, such as by using radio waves as part of a radar technique. In a first example, the techniques are implemented such that one hand of a user sets a context for a gesture that is defined by another hand of the user. In another example, a gesture recognition mode is utilized. In yet another example, detection of distance is used such that the same motions may be used to different between operations performed. In a further example, split gestures are supported. In another instance, entry into a gesture recognition mode may be implemented through touch and then recognized through three-dimensional orientation and motion of that hand or another.

    Abstract: This document describes techniques and devices for occluded gesture recognition. 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 smartphone providing radar-based proxemic context. The techniques and systems use a radar field to accurately determine a user's location and/or physical orientation with respect to an electronic device, such as a smartphone. The radar field also enables the device to receive 3D gestures from the user to interact with the device. The techniques allow the device to provide functionality based on the user's presence and/or orientation, and to appropriately adjust the timing, content, and format of the device's interactions with the user.

    Abstract: This document describes techniques and systems that enable a smartphone-based radar system for determining user intention in a lower-power mode. The techniques and systems use a radar field to enable the smartphone to accurately determine the presence or absence of a user and further determine the intention of the user to interact with the smartphone. Using these techniques, the smartphone can account for the user's nonverbal communication cues to determine and maintain an awareness of users in its environment, and only respond to direct interactions once a user has demonstrated an intention to interact, which preserves battery power. The smartphone may determine the user's intention by recognizing various cues from the user, such as a change in position relative to the smartphone, a change in posture, or by an explicit action, such as a gesture.
