This is the whiteboard. Ink lands here, decoupled from the camera view.
Point with your index finger (other fingers relaxed/curled)
to draw. Open your palm (all fingers extended) to erase
around your hand. Pick tool/size from the toolbar in the panel — that's
the only way to change them now.
Camera (drag me)-
Point at each glowing target and hold still for ~1s

Mode
Trackpad (default) draws with your laptop trackpad directly — no camera, no jitter, and no clicking: just glide your finger across the pad to write, keeping it resting there the whole time like a pen on paper. Pause for a moment to finish a word (there's no need to lift your finger), and your writing is auto-cleaned. Pick Eraser in the toolbar above to erase by gliding. Auto/Finger/Pencil are the webcam hand-tracking modes; switch to one and click Start camera to use it.
Board calibration
Maps your pointer onto the whiteboard plane so drawing stays accurate off-center or at an angle. Optional — works uncalibrated too.
