Command by sensors

Changing audio feedback requires to stop, take off gloves, take out phone, unlock phone, change setting, put back phone in pocket, put on gloves and hope I do not have to do this in bad weather.
Wait a moment. I have sensors on my feet, an app running. Suppose that when I'm standing still I lift up my right foot 3 times higher then 20cm and that changes the audio-feedback to the next item in the row and app reads new setting.
E.g.:

• Real-time audio: Off - SkiIQ only - SkiIQ and lift - Coaching - Monitoring - back to Off …..
• Change focus metric
• …
  Possible Sensor triggering movements must be intentionally and not something that could happen without intention to send command:
• standing still, lifting right foot x times; idem left foot
• standing still, lift up right foot and twist boot x times from left to right; left foot.
  App should give auditive feedback after changing setting
