Touchscreen Tests
Trace touch response, missed areas, simultaneous contacts, and drawing continuity.
Touchscreen Test
Test finger, stylus, and pointer contacts with a live touch point map and pressure readings.
Multi-Touch Test
Check how many simultaneous touch points your touchscreen can detect in the browser.
Touchscreen Dead Zone Test
Drag across a touch map to find missed cells, dead touch zones, and tracking gaps.
Tap Accuracy Test
Tap moving targets to estimate touch offset, calibration drift, and screen edge accuracy.
Touch Drawing Smoothness Test
Draw lines on a touch canvas to inspect gaps, wobble, jitter, and stroke smoothness.
Edge Touch Test
Test touchscreen corners and bezels for edge detection, missed taps, and weak contact zones.
Touch Event Log
Inspect pointer event IDs, pressure, coordinates, event timing, and input type from touch devices.
Before you begin
Contact positions, identifiers, and pressure come from Pointer Events where available. Pressure may be a default value on unsupported hardware. Browser gestures and palm rejection can interrupt contact tracking.
