Radar-Based Gesture Sensing and Data Transmission

摘要

This document describes techniques and devices for radar-based gesture sensing and data transmission. The techniques enable, through a radar system, seamless and intuitive control of, and data transmission between, computing devices. This radar system can both transmit data and sense gestures, thereby performing with a single system, control of many devices and data transmission with those devices. Not only can this provide control of many devices, from refrigerators to laptops, this radar system also allows high-bandwidth data transmission between devices.

主权项

1. A computer-implemented method comprising:
receiving selection, through one or more direction sensors of a radar-communication device, of a direction for projection of a radar transmission; projecting, through a radio element of a radar system of the radar-communication device, a directed radar transmission in the selected direction, the directed radar transmission transmitting data from a radar-communication device; receiving, at an antenna of the radar-communication device, a reflection caused by an interaction made with the directed radar transmission; determining that the interaction indicates a gesture made within the directed radar transmission; determining, based on the gesture, a selection concerning control of an entity; and passing the selection to the entity effective to cause the control.
