摘要： Methods and systems to provide location and navigation information to a user within a building. In an embodiment, low power radars may be used to locate and track a user. Moreover, the systems and methods described herein may take advantage of the known layout of a building, or may ascertain the layout using the radar devices. This information may be used to direct a user from a current location to a desired destination. In some contexts, such as stores, radio frequency ID (RFID) tags may be used to identify a particular destination, such as a particular product in a particular aisle in a store. Multiple persons may be tracked as they move about the building, so that the more frequently used paths may be identified for moving from point to point. These identified paths may then be used in constructing a path for a user who needs directions.

摘要： Systems, apparatuses and methods may detect a hand-based object in front of a touchscreen, determine one or more motion attributes of the detected hand-based object and initiate a halt of one or more user interface updates associated with the touchscreen if the one or more attributes correspond to an impending impact between the hand-based object and the touchscreen. In one example, the hand is detected based on a signal from one or more of a micro-impulse radar (MIR) device, an infrared (IR) depth sensor or a camera.
