Abstract: This document describes techniques and systems for reducing a state based on sensor data from an Inertial Measurement Unit (IMU) and radar. The techniques and systems use inertial sensor data from an IMU as well as radar data to reduce states of a user equipment, such as power, access, and information states. These states represent power used, an amount of access permitted, or an amount of information provided by the user equipment. The techniques manage the user equipment's states to correspond to a user's engagement with the user equipment, which can save power, reduce unwarranted access, and reduce an amount of information provided when the user is not engaged with the user equipment, thereby protecting the user's privacy.

Abstract: This document describes techniques and systems for authentication management through IMU and radar. The techniques and systems use inertial sensor data from an inertial measurement unit (IMU) and/or radar data to manage authentication for a computing device. By so doing, the techniques conserve power, improve accuracy, or reduce latency relative to many common techniques and systems for computing-device authentication.

Abstract: An artificial intelligence (“AI”)-based system is disclosed for presenting activity-specific views of relevant activity-specific content. An AI engine selects activity-specific content relating to a multitude of activities. The selected activities can have associated relevance scores exceeding a predefined threshold value. The selected activity-specific content can be used to render user interface (“UI”) elements in a UI for the activities. The UI elements present an activity-specific view of the activity-specific content relating to each activity.

Abstract: This document describes techniques and systems that enable a visual indicator for paused radar gestures. The techniques and systems use a radar field to enable an electronic device to accurately determine radar gestures, or other movement, by a user. Further, the electronic device can determine certain conditions that can make it difficult for the electronic device to properly determine the user's radar gestures. When the device includes an application that can be controlled using radar gestures (a radar-gesture application), and the conditions are present, the device can enter a gesture-paused mode. When the device enters this mode, the techniques provide a gesture-paused feedback element on a display, which lets the user know that there is at least one radar-gesture application available or running on the electronic device but that radar gestures cannot presently be used to control the application.

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: Restructuring a view of messages based on configurable persistence is provided. An application such as a communication application displays summaries of messages within a summary pane of a messaging user interface (UI). The messages include emails. An action is detected to reorder one of the summaries on a top location of a date section of the summary pane. Reorder options are displayed to identify a reorder time of the summary. A selection of one of the reorder options is detected as the reorder time. The summary is relocated to the top location of the date section of the summary pane to display the first summary at the top location of the date section during the reorder time.

Abstract: This document describes techniques and systems that enable an input-mode notification for a multi-input mode. A radar field enables an electronic device to accurately determine the presence or absence of a user near the electronic device. Further, the electronic device can determine whether an application that can receive input through radar-based gestures is operating on the electronic device. Using these techniques, the electronic device can present an input-mode notification on a display of the electronic device when the user is near to alert the user that radar gesture input is available for interacting with the electronic device. This allows the device to provide the user with feedback that can educate the user about what the electronic device is capable of, and allows the user to take advantage of the additional functionality and features provided by the availability of the radar gestures.

Abstract: Technologies are described related to communication interfaces for wearable devices. User experience with wearable devices may be enhanced through tailored views for communications, calendar items, actions associated with those, where the views and presentations may be dynamically selected and adjusted based on context, user, location, and device capabilities. Smart notifications and user-friendly note taking functionality may be enabled also based on context, user, location, and device capabilities. Other scenarios may be unlocked based on proximity and/or sensor data.

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: An artificial intelligence (“AI”) based system is disclosed for associating low-level user content, such as documents, email messages, and calendar invites, with high-level user activities using topics as an abstraction. The associations can enable a computing system to provide, among other things, activity-specific views that present a specific selection of low-level user content that is most relevant to a user at a particular point in time. The activity-specific views present the right information to users at the right time based on a context of a user and a user's past activities.

Abstract: This document describes techniques that enable facilitating user-proficiency in using radar gestures to interact with an electronic device. Using the described techniques, an electronic device can employ a radar system to detect and determine radar-based touch-independent gestures (radar gestures) that are made by the user to interact with the electronic device and applications running on the electronic device. For the radar gestures to be used to control or interact with the electronic device, the user must properly perform the radar gestures. The described techniques therefore also provide a tutorial or game environment that allows the user to learn and practice radar gestures in a natural way. The tutorial or game environments also provide visual feedback elements that give the user feedback when radar gestures are properly made and when the radar gestures are not properly made, which makes the learning and practicing a pleasant and enjoyable experience for the user.
