Storyboard of Functions
Perform an L-shaped gesture while hovering and touch down to run the command. In this animation, choose a brush color by hovering up-left.
Locus of attention is kept close to the work area. The technique leverages implicit learning of gestures.
Discoverability is a challenge given that the available commands are not permanently visible. Re-running a command requires the user to perform the same L-shaped gesture repeatedly.
