Before Beginning Setup
Stay Comfortable
Some people may experience discomfort such as nausea, motion sickness, dizziness, disorientation,
headache, fatigue, eye strain, or dry eyes when using mixed or virtual reality, particularly as they
adjust to using it. Typically, motion sickness and related symptoms occur when there is a mismatch
between what you see and what your body perceives. If you are prone to motion sickness in other
situations, are afraid of heights, get migraine headaches, have an inner ear disorder, or other health
conditions, you may be at increased risk of discomfort.
Certain Situations Can Increase Your Risk of
Discomfort
For example:
• Being a new user - symptoms tend to decrease as your vision system adapts
• Display not calibrated, or headset not oriented correctly on your head. Make sure
HoloLens is properly calibrated and that it is properly aligned by using the Calibration
application.
• Certain types of content, particularly games or movies that make you feel as if you are
moving through space or looking down from high, or interactions that involve tracking
moving objects
• Using HoloLens for extended periods without a break
• Using HoloLens in a completely dark environment that keeps you from seeing visual cues
with your peripheral vision
Consider Keeping Your First Sessions Brief
Start slowly and look around to get a feel for how the virtual objects and the outside world interact.
For most people discomfort should decrease as you get more practice over your first few sessions.
Take Periodic Breaks
Take breaks periodically and stop and rest if you experience any discomfort. The timing and length of
breaks may depend on the individual user and what you are doing with HoloLens.
If You Experience Discomfort
If you experience discomfort, stop using HoloLens and rest until you feel better. Sitting still in a well-
lit environment can help speed recovery from disorientation. If you feel disoriented, avoid activities
that require balance, coordination, or other capabilities until you recover. Be sure the display is
properly calibrated. Take note of the type of content you were viewing and other aspects of the
situation in which the discomfort occurred so you can adjust or ease into the situation next time.
People differ in the time they take to adapt. Consider taking more frequent or longer breaks.
