Ready
The Ready gesture is performed by making a closed fist and raising your index finger, much the
same way that you'd tell someone "wait a minute!" At its core, this gesture lets the device know
that you're about to make a selection gesture. Oftentimes the Ready and Air Tap (next section)
gestures are done sequentially without a pause to select something in the holographic space.
The Ready gesture by itself can be used to ensure that the device is seeing your hand (i.e.
you're in the field-of-view of the sensors). The cursor following your gaze will turn from a solid
dot to a ring when the device senses the Ready gesture.
Air Tap
The Air Tap gesture is your left mouse-click. Hover your gaze over what you want to select,
begin in the ready position, then firmly "click" your finger down and back up. The gesture is
similar to if you were tapping someone on the shoulder to get their attention.
