Abstract: Techniques for a dynamic radar mode modulation feature are described herein. A computer system associated with a device may implement a first radar configuration for a radar sensor. The first radar configuration may correspond to a first mode and comprise a first frame per second rate and a first difference threshold. The computer system may receive first data from the radar sensor in the first radar configuration. The computer system may determine a presence of an object within a field of view of the radar sensor based on the first data and the first difference threshold. The computer system may instruct the device to turn on based on determining the presence of the user. The radar sensor may be instructed to implement a second radar configuration associated with a second mode.

Abstract: This disclosure describes, in part, techniques for using presence detection in order to switch between power modes of a display device. For instance, the display device may operate in a first power mode by deactivating a display. While operating in the first power mode, the display device may use a sensor to detect a presence of a possible object. The display device may then switch to a second power mode in order to verify that the possible object is an actual object. In response, the display device may switch to a third power mode by at least activating the display and presenting a user interface using the display. The display device may then receive an interaction. In response, the display device may switch to a fourth power mode by at least presenting content.
