Mobile device-based radar system for applying different power modes to multi-mode interface

摘要

This document describes techniques and systems that enable a mobile device based radar system 104 to apply different power modes to a multi-mode interface 114 . The technique and system includes a user device 102 having a radar system 104 and an interaction manager 106 . The radar system 104 generates the radar field 110 , provides radar data, and operates in one of a variety of different radar power states. The user device 102 analyzes the radar data to detect the presence or movement of the user within the radar field 110 . In response to the detection, the radar system 104 changes from the first radar power state to the second radar power state. Based on this change, the interaction manager 106 selects a power mode corresponding to the second radar power state for the multi-mode interface 114 , and applies the selected power mode to the multi-mode interface 114 , so that the display device A corresponding display is provided via 116 .
