Advanced Sensor Calibration

Advanced sensor calibration lets you fine-tune the touch area using a grid-based warping system.
This process is optional but highly recommended when:

• The wall is not perfectly flat
• Certain areas of the projection require higher precision for touch and visual alignment

Testing Calibration

Test the calibration by touching the wall. A blue cross should appear at the contact point, confirming accurate touch-to-visual alignment.

For best results, use an assistant: one person adjusts the grid while the other touches the wall to verify hits.
