Improving tracking by calibrating your device

Holograms may jitter or appear at an incorrect depth if your HoloLens is not correctly calibrated for your interpupillary distance (IPD).

1. If you know your IPD, you can log in to Device Portal and set the IPD on the System -> Preferences page.
2. If you don't know your IPD, you can use the Calibration App to calculate it. The Calibration App will automatically adjust the device IPD. 

Your perception of holograms also improves with a comfortable and well fitted device. If you are feeling some discomfort from the weight of the HoloLens on your nose try the following:

1. Adjust the headstrap so that it fits firmly around your forehead and takes the weight of the headset
2. Slide the headset so that it sits just above your nose
3. Try replacing the nose bridge on the device (there are two sizes)
4. Contact lenses can be more comfortable for extended use that wearing glasses with the Hololens.
