Stroke Streamlining
The problem
Every tiny tremor in the hand becomes a kink in the ink, so slow careful lines look noisier than they feel.
The solution
Each sample is streamlined and smoothed into a stabler geometry before it is drawn.
This mechanic is best experienced with a pointer.

How it works
Seen in
Drawing apps
Freehand ink stays clean when the path lags slightly behind shaky input.
Note apps
Handwriting looks intentional instead of vibrating with every micro-movement.
Whiteboards
Slow annotation lines stay straight enough to read without post-processing blur.
Signature pads
Signatures keep character while losing high-frequency hand tremor.
