How to lift a pen:

Engage the muscles of your right arm and open your fingers. There’s a blue inked object on the work bench. Reach out towards it and, with your fingers, pinch its plastic body and lift.

How to raise your hand:

  1. From a relaxed position, tense the muscles of your arm, either side.
  2. Pull the lower arms towards the sky bending at the elbow.
  3. Stretch out your fingers as if saying hi. Doing so will give you more visual cues that can call attention.
