Drawing in 2D can be done on any whiteboard surface or extracted media such as images, videos, presentations and notes.
Instructions
Here’s how:
Grab a pen. See how to do that here
Move it close to a drawable surface like a whiteboard or a note
When you feel a vibration the pen will be “snapped” to the surface and you can start drawing by holding down the trigger
You can also see the 2D pen interaction in the video below.
