Answer 1

The Hololens 1 can't track your hand position. It only recognizes the air tap gesture, and uses your gaze pointer to select. You need a Hololens 2 if you want to track your hands.

Answer 2

Hand tracking is the newest feature of HoloLens2, it is not available on HoloLens (1st gen), so you cannot obtain hand position data from HoloLens1. We recommend that you modify the interaction model of your app to use head gaze instead of hand tracking as an input. More information please see:Gaze and commit
