Touch Screen Test
Touch or tap inside the shaded arena. Hits stay as labeled markers plus the last 41 trail dots to check mapping and drift across the panel (phones, touchscreen laptops, stylus). Pointer events unify mouse drag for desktops without touch.
Marks placed: 0
How to use
- Use your digitizer inside the bordered arena—the latest markers render brightest.

- Clear markers between runs.
