Fitting HoloLens - Having some trouble
Hello all --
I received my HoloLens unit yesterday. I'm blown away and quite amazed!
However, I am having some trouble with the fitting/getting the image right.
I've followed the instructions on the website/manual to place it on my head - but it always feels like the image is slipping down. Almost like I am wearing bifocals and I have to crook my head to see through the area where the image is. I keep adjusting it to get it right.
The other issue I've noticed is that holograms appear at an angle. For example if I place a 2D holographic window in front of me, the bottom left edge is cut off at an angle. I have to tilt my head a bit to get it to be "straight". Perhaps due to my fitting issue?
Lastly, there's a bluish reflection of holograms in the bottom of the lens. Occasionally I also get a rainbow effect in the left eyepiece. I've tried running the calibration a few times but it's still there.
I'm probably "doing it" wrong.
Any help that you could offer would be greatly appreciated!

Here is how I teach people to wear the device at the Holographic Academy:
0) Remove the nose piece (most people find this uncomfortable).
1) Handle the device using the arms on both sides (try to avoid touching the visor, as this can leave smudgy fingerprints that can interfere with sensors and your visualization of holograms).
2) Tilt the headband up slightly.
3) Push the headband back all the way to allow maximum clearance for the visor (especially if you wear glasses).
4) Expand the headband all the way out by using the adjustment wheel in the back.
5) Place the HoloLens on your head and align the headband to the top of your forehead (just under your hairline). Note: Where to position the headband for best comfort is unique to each individual and can change as you get more experience with the device (when I first started, I wore the headband up high on my head, but have since found it to be more comfortable at my hairline).
6) Tighten the headband. Make sure it's nice and tight, because you don't want the device moving around on your head, but don't make it so tight that it will cause an indentation/headache.
7) Move the visor in/out and tilt it up/down to ensure that you are seeing the entire holographic frame. You should be able to look straight out through the lenses, if you have to look down like wearing bifocals, then tilt the visor up.
8) Ensure that no part of the device is resting on your nose. All weight of the device should be distributed by the headband (if you use the nosepiece, this might be hard to achieve).
9) For long-term comfort, use the overhead strap that was provided with the device (check the quick start guide for more information).
10) To test the position of the visor, start the calibration or gesture tutorial. Both of these apps begin by marking the four corners of the holographic frame. You'll want to move the visor in/out, up/down until you can see all four corners simultaneously. If you've already been through the tutorial, simply use the 'bloom' gesture to dismiss it once you have the device fitted properly.
11) To remove the device, hold it by the arms on both sides and lift it up and over your head. I usually keep the headband in the tilted position so I don't have to fiddle with the angle again.After a few days wearing the device, you should have a pretty good handle on how big the holographic frame is and can quickly adjust the visor without doing step 10.
As for the blue image, it does sound like light reflections are to blame. However, there are certain colors that you should try to avoid using on the HoloLens, which includes white. White tends to show color separation, so you see rainbows or sometimes a doubled image when moving around. Use a lighter gray color instead, to help minimize this.
I hope this information helps some people feel more comfortable when wearing the device. Congratulations on getting your first HoloLens

Hi Runamuck,
Congrats on getting your device!!!! To respond to your first issue, my friend and I both had the same experience in regards to the image appearing lower on the lens, which now that you mention it is similar to looking through bifocal lenses. I was able to somewhat remedy the situation a bit by raising the device higher on my forehead - it intuitively felt "too" high - but ended up being just right. I adjusted the head band tight enough so that I could shake my head around and it wouldn't budge. The device was hovering above my nose instead of resting on it, which decreased the experience of looking through bifocals. I think that the angle of the lens may need to be adjusted on the devices in order to raise the image. Test out if the tightening and straightening of the device on your head also straightens out the angled holograms. The image does cut off if you are not looking at it straight on.
Can you explain the bluish reflection of the holograms in more detail? Does it happen on one spot of the lens more often? I sometimes have dark shard shapes that appear only when looking at the hologram of a browser window while surfing the web - which I was told happens sometimes when it is rendering. I haven't experienced the rainbow effect yet.
I hope this helps in some way.

Hi - I'm seeing almost what looks like a blue reflection of the hologram being presented in the lower part of my view. So if there's a white floating orb, I'll see a bluish reflection under it of the same orb.
It may be due to having the brightness too high?
I'm told by others that the blue hue could actually be caused by the overhead lighting in my space reflecting within the lenses?
I just received my device yesterday too and I've been experiencing the same things. I still can't quite the fit right; it's always sliding down and resting on my nose, which is very uncomfortable. I've tried arranging the inner and outer rings in different ways but it never stays where I put it. Honestly thinking about getting some duct tape to keep the outer ring from sliding back.
As for the blue reflection, I was seeing the exact same thing and was told that it has to do with overhead lights. It does seem to go away when I get the lighting in the room just right.
After a few days of fiddling, I've managed to sort out how to get it to fit properly. At first I think I was placing it too low on the bridge of my nose - this caused the view field to constantly look like I was having to tilt my head up to see things. What I ended up doing was fitting it so the nose-pads are actually not touching my nose and the lenses themselves are up a bit higher. This way the view is much better. I did this by placing the inner headband more around the crown of my head so the front of the headband is actually above my hair line (not just below it as normally suggested).
I was nervous about doing this at first because it causes the outer ring near the back to flex out a little to wrap around my head, but I was told it's designed to do this (for those bigger heads out there).
As far as the blue hue/rainbow - this was completely due to the lighting in my room. I noticed if I am in a room with even lighting or natural lighting this doesn't happen. Seems to only occur when there is uneven lighting in a room.
Yah it's totally based on the lighting. I have the same thing happen too. Nothing is wrong with your HoloLens, it's just the damn reflections. I wondered the same thing, but the same effect happens when the device is powered off, and it happens outside the rendering frame, so it's not a hardware problem.
Maybe Microsoft could throw on an anti-glare coating, much like what you get with glasses.
