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.

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; andpassing the selection to the entity effective to cause the control. 2. The computer-implemented method as described in claim 1, wherein the selection of the direction is received through orientation sensors included within the one or more direction sensors. 3. The computer-implemented method as described in claim 1, wherein the entity is a device to which the radar transmission is selected to be directed. 4. The computer-implemented method as described in claim 1, wherein the selection is to control data transmission between the entity and the radar-communication device. 5. The computer-implemented method as described in claim 1, wherein the directed radar transmission includes time-split radar transmissions, a first of the time-split radar transmissions transmitting the data and the second of the time-split radar transmissions configured to reflect radar from human tissue, and wherein receiving the reflection caused by the interaction receives the reflection from human tissue and from the second of the time-split radar transmissions. 6. The computer-implemented method as described in claim 1, wherein determining the gesture determines that the gesture is of a particular type and determining the selection is based on the particular type. 7. The computer-implemented method as described in claim 1, wherein determining that the interaction indicates the gesture determines that the gesture is a simple interruption by human tissue of the directed radar transmission. 8. The computer-implemented method as described in claim 1, wherein the directed radar transmission is a direct-beam narrow field. 9. 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; andaltering the data connection based on the selection. 10. The computer-implemented method as described in claim 9, wherein the selection is to begin the data connection and the altering the data connection performs a handshake protocol to begin a new data connection with another computing device that is associated with the radar-communication device. 11. The computer-implemented method as described in claim 9, wherein the selection is to cease the data connection and the altering the data connection ceases the data connection. 12. The computer-implemented method as described in claim 9, wherein the directed radar transmission is directed by a physical orienting of a radar element of the radar-communication device toward the radar antenna associated with the computing system. 13. The computer-implemented method as described in claim 12, wherein the directed radar transmission is a broad field having different characteristics at a center of the broad field than at a periphery of the broad field and further comprising determining, based on characteristics of radar received that the directed radar transmission is directed to a computing device on which the method is performed. 14. The computer-implemented method as described in claim 12, wherein the directed radar transmission is a directed-beam narrow field and further comprising determining that the directed radar transmission is directed to a computing device on which the method is performed based on receiving radar from the radar-communication device. 15. The computer-implemented method as described in claim 9, wherein the directed radar transmission includes time-split radar transmissions, a first of the time-split radar transmissions sending data and the second of the time-split radar transmissions configured to reflect radar from human tissue, and wherein receiving the reflection caused by the interaction receives the reflection from human tissue and from the second of the time-split radar transmissions. 16. The computer-implemented method as described in claim 9, wherein determining the gesture determines that the gesture is of a particular type and determining the selection is based on the particular type. 17. The computer-implemented method as described in claim 9, wherein the data connection is to a third-party device connected with or associated with the radar-communication device. 18. The computer-implemented method as described in claim 9, further comprising: receiving a second reflection caused by a second interaction made with the directed radar transmission;determining that the second interaction indicates second gesture data associated with a second gesture made within the directed radar transmission; andpassing the second gesture to an application, an operating system, or a device effective to control the application, the operating system, or the device. 19. 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; anda 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. 20. The radar system as recited in claim 19, wherein the radar system is operably coupled with another computing device, the data communication includes content streaming, and the alteration of the data communication includes one of: initiating a stream of content between the computing device and the other computing device; orceasing the stream of content between the computing device and the other computing device.
