Calibrate Custom Shape Skin

Calibrate Custom Shape Skin

Drag Mode Calibration

Drag Mode Calibration allows you to calibrate customised, shaped (non-rectangular) sensors or define a custom active touch area on a standard DISPLAX Skin sensor -useful when the sensor’s usable touch area is smaller than its full size.

Use this feature for:

  • Custom-shaped sensors (circular, triangular, elliptical).

  • Limiting touch detection to only part of the sensor.

How to Use Drag Mode Calibration

  1. Launch DISPLAX Connect and go to the CALIBRATION tab.

  2. If multiple monitors are connected, select the correct display.

  3. Choose Drag Mode.

  4. Select a shape: Rectangle, Circle, Ellipse, or Triangle.

  5. Click CALIBRATE.

A black screen will appear with the message:

"Please select the area."

Use your mouse to draw the calibration area.

  • Red shape → area is too small.

  • Green shape → valid area.

You can move, resize, or rotate the shape as needed.

Press Spacebar to continue, or R to restart.


Shape-Specific Instructions

1. Rectangle

  • Click and drag from one corner to the opposite corner of the interactive area of the touch sensor, leaving ~2cm from the edges.

  • You can move, resize, and rotate the shape.

  • When the green square is well-positioned, press Spacebar.

  • Four calibration points will appear — touch each target until a green circle closes around it, with a message saying. Wait... Processing point data.

  • Stop touching and repeat the process with the remaining targets, until a message displays Geometric calibration succeeded.


2. Circle

  • Click and drag to draw the circle.


  • Leave ~2 cm border between the circle and the display edges to keep calibration points visible.


  • Press Spacebar to start the four-point calibration.

  • Four calibration points will appear — touch each target until a green circle closes around it, with a message saying. Wait... Processing point data.

  • Stop touching and repeat the process with the remaining targets, until a message displays Geometric calibration succeeded.

3. Ellipse

  • Click and drag to create the ellipse.

  • Maintain ~2 cm border from sensor e.


  • Press Spacebar to continue start calibration.

  • Four calibration points will appear — touch each target until a green circle closes around it, with a message saying. Wait... Processing point data.

  • Stop touching and repeat the process with the remaining targets, until a message displays Geometric calibration succeeded.

4. Triangle

  • Click and drag to draw the triangle.

  • On-screen message will guide you:

    “Mouse movement will follow hypotenuse of clockwise triangle.”


  • Leave ~2 cm border around sensor edges.

  • Press Spacebar for the three-point calibration — touch each target until a green circle closes around it, with a message saying. Wait... Processing point data.

  • Stop touching and repeat the process with the remaining targets, until a message displays Geometric calibration succeeded.

Calibration Results

Success:

“Geometric calibration succeeded.”

You will return to the DISPLAX Connect interface.

Invalid area:

“The selected area is invalid, please select again.”



Increase the shape size until it changes from red to green.

Best Practices & Tips

  • Perform calibration after final physical installation (screen set, air-gap settled, sensor mounted).

  • Use a single consistent touch point per calibration target (e.g., a fingertip) and hold steady until completion.

  • Avoid recalibrating unless needed (sensor relocated or performance degraded) — the controller retains the calibration profile.

  • Do not move your finger whilst touching the target during calibration.
