Claim Text:
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.
