Best Practices

SimSpray™ uses a magnetic tracking system for motion tracking.

  1. Follow the Positioning guide to best locate your unit and to understand about environmental influences on the fidelity of the motion tracking.
  2. If you have a nearby SimSpray™ or VRTEX™ unit, these units may have overlapping frequencies with your unit:
    1. For Users with the 2nd Generation Tracker Stand (see Hardware Components), use the Frequency button to change frequencies.
    2. For all other Users, consider relocating this SimSpray™ unit or your other SimSpray™ or VRTEX™ units.
  3. For users with a v3 Case (see Hardware Components), to help reduce the need to Recalibrate:
    1. Keep the Gun drawer partially or fully pulled out.
    2. When not wearing the FMD, place the FMD on this drawer.
    3. When not holding the Gun, place the Gun on this drawer.
  4. If the motion tracking does not match your motions, use the Recalibrate button.

Troubleshooting

Uncalibrated or Unstable Calibration

Symptoms

If sensor calibration is uncalibrated or becomes unstable, the Recalibrate warning may display in the Live Scene.

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 and Solutions
  1. Follow the Best Practices above.
  2. Use the Recalibrate button.

Nearby Conductive Materials

Symptoms
  • The Gun and/or FMD do not follow the path when the User moves them, especially when the Gun and/or FMD get close to nearby objects in the environment (e.g., metal walls, cabinets, or the floor).
Causes and Solutions
  1. Follow the Best Practices above.
  2. Follow the Positioning guide.

Electromagnetic Interference

Symptoms

If there is electromagnetic interference from the surrounding environment, the motion tracking may be degraded.  Users looking through the FMD (Face Mounted Display) may experience the following symptoms in the Live Scene:

  • The Gun or FMD appear to move slowly or rotate even though the physical devices are not being moved.  This is normally an indication of other magnetic tracking systems in the same space.
  • The Gun or FMD appear to jitter excessively during use.  This is normally an indication of environmental interference.
  • Even after using the Recalibrate button:
    • The Gun or FMD do not follow the path the User moves and rotates them.
    • The Gun or FMD keep jumping position.  Users may appear to be on, in, or under the floor.
    • The Gun or FMD quickly shift or slide even though the physical devices are moved smoothly.
    • 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

These conditions can occur if there is electromagnetic interference from the surrounding environment.  The following are some potential sources of interference:

  • Fluorescent lights
  • Ballasts
  • Air handlers
  • Generators
  • Other magnetic tracking systems, such as nearby:
    • SimSprayTM units on the same or overlapping frequencies
    • VRTEXTM units on the same or overlapping frequencies
Solutions

When the above conditions occur, try the following:

  1. Change the Frequency.
  2. Relocate the SimSpray™, using the Positioning guide.  Move the unit away from any potential causes of electromagnetic interference (see above).
  3. Turn off the lights.
