Touchscreen

Multi-touch tracking and paint mode to verify touch coverage and responsiveness.

Overview

Touchscreen is a full-screen tool that shows where your touches are being detected. It's useful for spotting dead zones, dropped drags, or phantom touches.

Touchscreen starts in a full-screen view.

Tracking mode: crosshairs and per-touch info labels.

Use the gear button to open the menu.

Paint mode: draw strokes to verify continuous tracking.

Modes

Touchscreen has two modes:

• Tracking: shows active touch points with crosshairs and details.
• Painting: draws stroke paths so you can verify continuous input.

Tracking Mode

Each active touch shows:

• Crosshairs at the touch location
• X/Y coordinates
• Pressure/force (when available)
• Azimuth angle (when available)
• Touch type: Direct (Finger), Indirect, Pencil, or Pointer (indirect pointer)

Touches have a fade-out animation when released, rather than disappearing instantly.

Paint Mode

In Paint Mode, touches draw white strokes on a black background. Multi-touch painting is supported -- each simultaneous finger creates its own separate painting path, which is useful for verifying multi-touch behavior. This makes it easy to check:

• Continuous drags (no gaps)
• Edge tracking (corners and bezels)
• Multi-touch registration

Controls Menu

Tap the gear button to open the menu:

• Paint Mode / Track Mode: switch modes.
• Clear: clears drawing (only enabled in Paint Mode).
• Close: exits the tool.

The gear button cycles through four corners (top-right, top-left, bottom-left, bottom-right) if you touch near it, so it stays easy to tap without interfering with your test area.

Tips

• Remove gloves and clean the screen for more consistent results.
• If you use a screen protector or thick case, test with and without it.

Notes And Limitations

• Pressure/angle values depend on hardware and input type (for example, Apple Pencil).
