Running Full Calibration

For full calibration, you must follow the steps for basic calibration and then complete additional steps.

To complete full calibration, you need the calibration board and two corner guides.

Full Calibration

To run full calibration

  1. On the Microsoft Surface desktop, right-click the Calibrate Vision System shortcut, and then click Properties

  2. In the Target box, replace "/w" with "/a", and then click OK.

    You might need to click Continue twice in the Access Denied window and the User Account Control permissions window.

  3. Double-click the Calibrate Vision System shortcut.

  4. Complete the basic calibration:

    1. Remove all items from on top of the Microsoft Surface screen, and then click OK.

    2. Position the mouse pointer over the OK button.

    3. Place the white side of the calibration board so that it completely covers the display area of the Microsoft Surface unit, and then click OK. (You can also press SPACEBAR to dismiss the dialog box.)

    4. Remove the calibration board.

      For more information, see Running Basic Calibration.

  5. In the Calibrating geometry dialog box, click OK (or press SPACEBAR) to dismiss the dialog box.

  6. Position the corner guides on the Microsoft Surface tabletop:

    1. Remove the brown paper from the back of one of the corner guides to reveal the removable adhesive film.

    2. Position the corner guide on one of the four corners so that the inner "V" of the corner guide is aligned to the edge of the projected display on the Microsoft Surface tabletop.

    3. Position the other corner guide in the same manner on the diagonally opposite corner of the Microsoft Surface tabletop. After you position both corner guides, the tabletop should look similar to the following illustration.

  7. Place the checkered side of the calibration board down on the Microsoft Surface screen, and line up the outer edges of the calibration board so that both sides of both corner guides display the same markings.

    That is, all four sides of the calibration board must line up with the same markings (for example, "B") on both sides of both corner guides.

  8. When you are sure that the calibration board is positioned properly, press the RIGHT ARROW key to start the calibration process.

    Calibration might take several seconds. When calibration is complete, you will hear a "tada" sound.

  9. Remove the calibration board, and then close the calibration application.

  10. Remove the corner guides, and put them back on the brown paper (with the smooth side of the brown paper against the adhesive side of the corner guide).

    (The corner guides should remain sticky through 5–10 calibration procedures, so you can reuse them.)

  11. Modify the Calibrate Vision System shortcut again by changing "/a" back to "/w" in the Target box.

    It is important to change the shortcut command back to the basic calibration configuration because you will run basic calibration much more often.

  12. Verify that the calibration was successful.

    • On commercial Microsoft Surface units, double-click the Surface Input icon on the left side of the Microsoft Surface desktop, and then double-click the Surface Shell icon. Perform various touch gestures in the active attract application and other installed applications.

    • On developer Microsoft Surface units, use the DataVisualizer application to verify that touch is working properly.

    If touch does not work on any or some parts of the Microsoft Surface screen, perform full calibration again.

What If Full Calibration Fails?

If you complete the preceding full calibration procedure, you might get the following error message.

Calibration error message

If you see this error message, you should do the following:

  • Make sure that there is no direct or harsh lighting near the Microsoft Surface unit. A lamp that is shining near the unit can cause erroneous black or white reference snapshots. Remove or turn off the lamp or light and restart the calibration procedure.

  • Make sure the calibration board is correctly positioned on the corner guides. If the board is tilted or misaligned, the cameras cannot find certain reference points on the checkered side of the board and calibration fails. If the board is misaligned, close the calibration tool, adjust the calibration board, and then restart the calibration procedure.
