1. An apparatus comprising:
- at least one processor; and
at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to at least;
detect that an application is being started on the apparatus;
in response to the application being started on the apparatus, turn on a continuous wave doppler radar at the apparatus and transmit radio signals that comprise the continuous wave doppler radar, wherein the radio signals are at least partially reflected by a human body of a user of the apparatus;
receive the transmitted radio signals after having been at least partially reflected by a gesture by the human body of the user;
detect in the received radio signals a predetermined time-varying modulation caused by the gesture by the human body of the user and that is present in a modulation of the received radio signals as compared to a modulation of the transmitted radio signals, wherein detecting the predetermined time-varying modulation of the received signal comprises detecting a doppler frequency shift in the continuous wave doppler radar of the radio signals transmitted from the apparatus, wherein the doppler frequency shift comprises a frequency modulated continuous wave variation caused by the gesture by the human body of the user;
associate the detected predetermined time-varying modulation with a predetermined user input command; and
based on the associated predetermined user input command control at least one operation of the application on the apparatus.

Abstract
An apparatus including: a radio transmitter configured to transmit radio signals that are at least partially reflected by a human body; one or more radio receivers configured to receive the transmitted radio signals after having been at least partially reflected by a human body of a user; a gesture detector configured to detect a predetermined time-varying modulation that is present in the received radio signals compared to the transmitted radio signals; and a controller configured to interpret the predetermined time-varying modulation as a predetermined user input command and change the operation of the apparatus.

17. An apparatus comprising:
-
a controller configured to detect that an application is being started on the apparatus, and in response to the application being started on the apparatus turn on a continuous wave doppler radar at the apparatus; a radio receiver configured to receive radio signals that comprise the continuous wave doppler radar after having been at least partially reflected by a gesture by a human body of a user of the apparatus; a gesture detector configured to detect in the received radio signals a predetermined time-varying modulation caused by the gesture by the human body of the user and that is present in a modulation of the received radio signals as compared to a modulation of the radio signals before the reflection, wherein detecting the predetermined time-varying modulation of the received signal comprises detecting a doppler frequency shift in the transmitted continuous wave doppler radar from the apparatus, wherein the doppler frequency shift comprises a frequency modulated continuous wave variation caused by the gesture by human body of the user; an interface for providing the detected predetermined time-varying modulation as an output; and the controller configured to associate the detected predetermined time-varying modulation with a predetermined user input command, and based on the associated predetermined user input command control at least one operation of the application on the apparatus. - View Dependent Claims (18)

19. A method comprising:
-
detecting, by an apparatus, that an application is being started on the apparatus, and in response to the application being started on the apparatus turning on a continuous wave doppler radar at the apparatus; transmitting, by the apparatus, radio signals that comprise the continuous wave doppler radar, wherein the radio signals are at least partially reflected by a human hand; receiving, by the apparatus, the transmitted radio signals after having been at least partially reflected by a gesturing human hand; detecting, by the apparatus, a predetermined time-varying modulation, characterizing the gesture, that is present in a modulation of the received radio signals compared to a modulation of the transmitted radio signals, wherein detecting the predetermined time-varying modulation of the received signal comprises detecting a doppler frequency shift in the transmitted radio signals based on the continuous wave doppler radar, wherein the doppler frequency shift comprises a frequency modulated continuous wave variation caused by the gesturing human hand; and controlling, by the apparatus, an operation of the application on the apparatus in dependence upon the predetermined time-varying modulation. - View Dependent Claims (20, 21, 22, 23)
