SimSpray motion tracking sensors may get confused under certain situations.  When this happens, Users should Recalibrate the sensors.


Note: requires 3.x hardware.  See Versions.

See Troubleshooting.  Search for “Reset Space” and “Recalibrate” as well as other motion tracking recommendations.

Symptoms of Uncalibrated or Unstable Calibration

If you see the Recalibrate warning while in the Live Scene, you will need to Recalibrate.

Additionally, if sensor calibration is uncalibrated or becomes unstable, Users looking through the FMD (Face Mounted Display) may experience the following symptoms in the Live Scene:

  • Users appear to be on, in, or under the floor.
  • The Gun does not follow the path when the Users move it.
  • When facing the physical Tracker Stand, Users do not see the Part in the FMD.
  • When holding the physical Gun in front of them, Users do not see the Gun in the FMD.
  • The Gun jumps to another position.  This symptom typically occurs when the Gun moves from the front side of the stand to the back side of the Tracker Stand or vice versa.
  • When standing in front of the Tracker Stand, your view in the FMD looks as though the virtual Part, environment, and Tracker Stand are rotated to the left or the right.

Causes of Uncalibrated or Unstable Calibration

These conditions can occur for a variety of reasons including:

  • The FMD, Gun and/or Tracker Stand come too close to metal.
  • The FMD and/or Gun are moved outside the recommended Painting, Blasting, or Coating area range.
  • The FMD and/or Gun are located behind the Tracker Stand when calibration takes place.

Solutions to Uncalibrated or Unstable Calibration

When the above conditions occur, Users should Recalibrate sensors.

To Recalibrate Sensors:

  1. Stand in front of the Tracker Stand, while wearing the FMD and holding the Gun.
  2. Tap the SimSpray™ tab and then tap Recalibrate.
  3. Follow the onscreen instructions to Recalibrate sensors.

As the system Recalibrates, you may see the following on the Touch Screen:

Note: If you see Hold, then please stand still.  If that does not help, then step closer to the Tracker Stand.

Okay indicates that the Recalibrate was successful.

If Recalibration does not address these conditions, try:

  1. Relocating the SimSpray, using the Positioning guide.
  2. Changing the motion tracker’s Frequency.
