Abstract: Example embodiments include an example method that involves detecting, via a gesture-detection sensor of a head-mountable device (HMD), a first gesture in a buttonless-touch region. The buttonless-touch region is located behind an ear of a wearer of the HMD. The method also includes activating a voice interface responsive to detecting the first gesture and, while the voice interface is activated, receiving an audio input signal via a microphone. The method further includes detecting, via the gesture-detection sensor, a second gesture in the buttonless-touch region and, responsive to detecting the second gesture, deactivating the voice interface. The method still further includes processing the audio input signal to determine a voice command having a start-point corresponding to the detected first gesture and an end-point corresponding to the detected second gesture.
