[First impressions] After setting up the Vive Ultimate tracker, I spent one night and had a very hot night. I will introduce the advantages and disadvantages.

I spent the night (about 7 hours) and report that I had a very hot night. I tried it with both feet on, not full traction.

 

[Previous article]: The article I actually set up.

This article will be the one we tried after this article. The following is based on the assumption that you have checked the following.

The Vive Ultimate tracker is a great tool for setting up the Vive Ultimate tracker, with actual photos of the settings and the points that I got stuck on!

I like it here.

(1) Very low calibration frequency.

Comparison: IMU method device
I had no trouble with the IMU method, where the device would shift more and more and I had to calibrate it after about 20 minutes, and calibration was not necessary for a long time. The misalignment is almost as small as with the Vive Tracker 3.0.

(2) Highly immersive with normal movement.

Comparison: IMU method device, Vive tracker 3.0
Most VRchat users basically do nothing more than standing, sitting, and sleeping, so they don’t move around too much, even when in full tracker mode. Therefore, in that range of operation, the Ultimate tracker is sometimes better than the Vive tracker 3.0 as well as the IMU method. For example, when you put your feet on top of each other’s feet, the unevenness of the tracker does not spoil the immersive experience, so it is suitable for expressions in which the trackers are close together.

(3) Long operating time without calibration

Comparison: IMU-based devices

Due to the above, the actual operating time without calibration is long. Because of the camera-based format of the device (there may be something extra), the correction always works, and there is no trouble such as a messed up body when you wake up in the morning, which occurs in the case of the IMU method. Here is how it looks after spending the night. The toes are actually stacked on top of each other.

Here’s what’s wrong

(1) Feels a little hot when operated barefoot

Comparison: IMU-based device, Vive Tracker 3.0
It is not very hot, but after spending the night, you can clearly feel the heat level as “something slightly warm”. It’s not a “warmer” heat either. It is not so hot that I would consider low-temperature burns. Since this is the case with the base attached, it would be a bit hot without it, so it is best not to wear it where the skin is directly exposed. Also, you can feel the heat, so the immersive feeling is lost to some extent. Personally, I could feel it as soon as I woke up. Without this countermeasure, I would not recommend this for VR sleep, etc. If you are operating barefoot + E0z belt, etc., you may want to consider countermeasures. By the way, there are people who wear fins to dissipate heat, but we do not recommend it because we think it is dangerous. We think it is necessary to take countermeasures such as wearing socks, avoiding long hours of operation, and not putting it on the thin part of the skin.

 

(2) Very heavy

Comparison: IMU-based device, Vive Tracker 3.0

It is very heavy. In my case, it was my foot, so I felt like I was wearing two Vive Tracker 3.0. You can blatantly feel it when you wear it on the tip of your foot or other parts of your body. The Ultimate tracker is a compact shape filled with density, commonly known as an ohagi, but it is heavy because it is not made lighter as you go to the tip like the Vive tracker. It is also heavier than the Vive tracker because of the height of the pedestal, which explains why the Eoz tracker belt is not made with screws for the Ultimate, but with claws for the pedestal. However, even if the E0z tracker belt is used, it is purely heavy, so even if the tracker belt is changed to a dedicated one, it will still be heavy.

 

(3) It’s going to come off, fly off, and break.

Comparison: IMU method device, Vive tracker 3.0
The above are the disadvantages caused by the above. This is a very different point from Vive Tracker 3.0. If you do the same kind of intense movement, the tracker itself will be subjected to gravity and acceleration, the screws will loosen, it will come off and fly somewhere, and you are likely to hit a wall, etc. and break it. The trouble is that it will come off. In my case, it is also Vivetracker 3.0,

(4) Not suitable for quick limb movements.

Comparison: IMU method device, Vive tracker 3.0
It is not suitable for quick limb movements due to the above, because it is heavier than other devices. (Unimotion and Haritra Wireless are better.) If you can do it even if it is heavy, I think this one can express quicker movement because the positional deviation from reality is quite small.

 

(5) It’s hard to tell at all how much room setup needs to be done to get better.

Comparison: IMU-based device, Vive Tracker 3.0
As I wrote extensively in the settings section, I have no idea how accurate the room setup is and what needs to be improved to improve the accuracy, so I cannot immediately think of a solution when I have a problem or an improvement plan when I want to improve the accuracy.

(6) Because the setup method is difficult at this point, I can’t come up with a solution compared to vive tracker and it takes a lot of time.

Comparison: Vive tracker 3.0
As I wrote extensively in the setup section, there are a few points where the setup gets stuck, and it takes time. I think the base station installation is more intuitive and quicker to solve. It is tough when you get stuck, but I hope this article will help you here.

(7) USBC is tight, and charging by direct insertion is deprecated.

Comparison: IMU-based device, Vive Tracker 3.0
Due to the weight of the above, I am afraid that if the USBC plugs into something a little hard (even though I have 3 of them, they are all different in that area, so some are harder than others), it won’t go in properly and I might bend the terminal or something. (I think this can be solved by using a type of magnet that sticks together.

(8) There is a ball in a strange place at the beginning, and it goes back to normal after a while of use.

Comparison: Vive tracker 3.0
When you play VRchat for the first few minutes, the white sphere may be in a strange place when you calibrate it. However, after using it for a while, it will be corrected and return to a position closer to your body. So it may be a little difficult when you are just getting into the game.

Despite the many disadvantages, the tracking accuracy is quite good, and I personally recommend it for that.
I would like to go back to vivetracker since I am doing this under a base station environment, but I have not yet read up on how to use it, so let me check it out a bit more. It’s in a category that I can highly recommend under a no-base-station environment.

That’s all. I will write the next article as a comparison and verification section.
