Putting on the VIVE Cosmos Elite headset

Before wearing the headset for the first time, make sure to do the following:

Peel off the protective film on the lenses.
Fully loosen the band and peel off the protective film starting from the left side of the band.

putting_on_the_vive_cosmos_elite_headset_htc_vive_99hasf006-00_cosmos_elite_headset.png

Detach the velcro fastener on the top strap, and then loosen the band by turning the adjustment dial counter-clockwise.
While holding the visor with one hand, pull up the band.
Hold the visor to your eyes. Adjust the position of the visor until you see a clear image inside the headset.
Pull down the headset band around the back of your head until you hear a click. The click indicates that the headset band has locked into place
Important: When you pull down the band, make sure the headset cable is not caught in between the band and your head. Let the headset cable run straight down your back.
Turn the adjustment dial clockwise until the headset fits snugly.
Make sure the visor faces straight ahead. If the band sits too low or high on the back of your head, the visor will be tilted. It will also be difficult to position the on-ear headphones properly on your ears. If there's light leakage around the areas of your nose or cheeks, adjust the position of the band.
Adjust the top strap until snug, and then fasten the velcro strap.
If there's light leakage around the areas of your nose or cheeks, readjust the strap and reposition the band.

Can I wear prescription glasses while using the headset?
Most glasses fit inside the headset. Make sure that no part of your glasses scratch the headset lenses.

Adjusting the IPD on the headset

Interpupillary distance (IPD) is the distance between the centers of your eyes.

If you don't know your IPD, see How can I find my IPD?. Use this measurement as a guide to adjust the distance between the lenses of the headset so that you'll have a better viewing experience.

To increase the distance between the lenses, rotate the IPD knob clockwise. To decrease, rotate the IPD knob counterclockwise.

adjusting_the_ipd_on_the_headset_htc_vive_99hasf006-00_cosmos_elite_headset.png

As you adjust the IPD, you'll see a prompt indicating the current distance between the centers of the lenses.

Why is accurate IPD important?

Accurate IPD settings help get a clear image and reduce eye strain.

The headset lenses focus images toward their optical center. This is sometimes called the "‍sweet spot"‍ in the VR industry. By adjusting the IPD knob, you can tune the sweet spot for the most comfortable view. Misaligned IPD and improperly adjusted headsets are common causes of blurry images, dizziness, and eye strain.

How can I find my IPD?

There are several ways to estimate your IPD.

The most accurate way to determine your IPD is to consult a professional optometrist or eye doctor. You can also estimate your IPD by doing any of the following:

Use a ruler and a mirror. See below for detailed instructions.
Through experimentation. See below for detailed instructions.
Using third-party apps or websites.

NOTE; Third-party apps or websites may collect personal data. HTC can neither guarantee the accuracy of IPD measured through third-party apps or websites nor ensure the security of your personal data.

Estimating your IPD in a mirror

You can estimate your IPD with a ruler and mirror.

This method requires a millimeter ruler.

Stand directly in front of a mirror, and then hold the ruler up to your eyes. Make sure that the ruler is level. If you're using a flexible ruler, make sure not to bend it.
Align the zero mark with the center of your pupil. You may need to close your other eye to get a clear measure.
Check the millimeter mark on the other eye. You may need to close the first eye to get a clear measure.
Make a note of your IPD measurement. You may want to recheck several times to make sure your reading is accurate.

Tip: You can also ask a friend to help you measure instead of using a mirror. Make sure you're looking straight ahead while they measure.

Estimating your IPD through experimentation

You can estimate IPD by trying different settings. This method is very convenient, but might be less accurate.

While wearing the VR headset, focus on text or lines at the center of view. If no text is present, open a screen in VR with text.
Adjust the IPD knob until the text is clear. Note the number for future use.
If the image in one eye is clearer than the other, adjust the headset position. Repeat until images are clear for both eyes

Flipping up the visor

Take a break from VR to check your surroundings without having to take off your headset.
While wearing VIVE Cosmos Elite, hold the visor with one or both hands, and then gently flip it up.
To return it to its original position, tilt the visor down until it completely covers your eyes.
If you wear large glasses, you may need to adjust the headset to sit higher on your head when flipping the visor up or down.

Connecting a USB device to VIVE Cosmos Elite

You can connect a compatible USB Type-C device to VIVE Cosmos Elite using a USB cable.

While holding the visor with one hand, pull up the band.
Detach the face cushion frame from the headset. To release the frame from its latches, gently pull on any side of the frame starting from the bottom, and then pull one side at a time on the top.
Important: Avoid pulling or squeezing on the sides of the face cushion frame to prevent damaging the frame.
Insert the cable connector of the device into the USB Type-C port on the headset.
Align and push the tabs on the face cushion frame into their corresponding slots on the headset. Make sure to position the ridge of the face cushion frame below the headset, audio, and USB cables. You'll hear a click when the face cushion frame locks in place.

What is motion compensation?

Motion compensation is a feature that helps smooth frame rates in VR applications for a more seamless visual experience. If an app is unable to consistently deliver the needed frame rate (90 FPS for VIVE Cosmos Elite), motion compensation reduces the frame rate by half, and then uses advanced prediction algorithms to synthesize the missing frames. The result is smoother performance without stuttering or lag, while requiring less processing power to render. This can also help relieve disorientation and motion sickness caused by VR lag.

Motion compensation can further reduce the frame rate below half, and synthesize additional frames as needed. However, synthesized frames may have artifacts in some apps.

Here's how to enable motion compensation:

From VIVE Console, click > Settings > Video. Then, turn on the Motion compensation On/Off switch.
Supported graphics cards include:
NVIDIA GeForce GTX1060 or better. AMD GPU support coming soon.
