Advanced sensor calibration

Advanced sensor calibration allows you to fine-tune the calibration using a grid-based warping input. This process is optional but highly beneficial when the wall is not perfectly flat or when certain areas of the projection require higher precision in touch positioning and visual response alignment.

Starting advanced calibration

  • Open the UI and navigate to the Settings tab located at the top of the screen.
  • Find and click on the Advanced Calibration section.
  • Click START CALIBRATION button

Controls

To fine-tune the calibration, use the mouse and keyboard to adjust the grid. Below is a table of controls:

Shortcut Action
Mouse Left-click select single point
Shift + Mouse Left-click select multiple points
V select vertical line
H select horizontal line
Arrows move selected points
R reset selected points
Esc save and exit

Moving the grid

To adjust the grid, select the points you want to move and reposition them using the arrow keys. You can select individual points, multiple points, or entire horizontal and vertical lines. Additionally, you can reset specific points to their default (unwarped) positions by selecting them and pressing the R key. Below are some examples:

Testing calibration

During the grid setup, it's important to test the calibration by touching the wall. When you touch the wall, a blue cross should appear at the point of contact, ensuring accurate alignment between touch position and visual response. It is recommended to perform this test with an assistant: one person adjusts the grid while the other touches the wall to see where the hit is registered. Refer to the image below for an illustration of this process.
