Abstract
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.
Claims20
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 the 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, at a computing system associated with the radar-communication device, that the interaction indicates gesture data associated with a gesture made within the directed radar transmission;
- determining, based on the gesture data, the gesture;
- determining, based on the gesture, a selection concerning control of an entity;
- and
- passing the selection to the entity effective to cause the control.
A computer-implemented method comprising:
- receiving, at a radar antenna of a radar system, a directed radar transmission from a radar-communication device, the radar antenna configured to receive the directed radar transmission and reflections of the directed radar transmission;
- receiving, at the radar antenna of the radar system, a reflection of the directed radar transmission caused by an interaction made with the directed radar transmission;
- determining, at a computing system associated with the radar system, that the interaction indicates gesture data associated with a gesture made within the directed radar transmission;
- determining, based on the gesture data, the gesture;
- determining, at the computing system and based on the gesture, a selection concerning a data connection;
- and
- altering the data connection based on the selection.
A radar system comprising:
- a radio element configured to provide a radar transmission, the radar transmission transmitting data and capable of interacting with human tissue;
- a radar antenna configured to receive reflections from interactions by the human tissue in the radar transmission that transmits the data and is capable of interacting with the human tissue;
- a signal processor configured to process the received reflections in the radar transmission sufficient to determine the received reflections in the radar transmission comprise gesture data associated with a gesture;
- and
- a system manager configured to determine the gesture from the gesture data and to cause a data communication to be altered between the radar system and a computing device, the alteration based on the determined gesture.
