I saw that Flipper Zero on your desk, you bold boy. but I imagine its a tool that would help with slime network mapping, with everything on wi-fi or some wireless signal?
good review
ohhh quest bench...cryptic
wwwwwwwww
Another reason the shipments were delayed was due to the FCC getting in the way. They claimed the chips were to be used in phones, not in VR Trackers, and denied the shipments. This led to them having to ship everything back to their main facility, get all the paperwork done, get approved by the FCC, change the labels on every single tracker, repackage it all, and then ship them back out.
It has been an absolute mess. I have a slew of emails explaining the whole situation. They have been VERY good about keeping me fully up to date.
Just to clear up a few things:
1. The skating can be heavily mitigated by our anti-skating option, which can be dialed up or down depending on personal preference. The better your skeleton is, the less you will need this.
2. The autobone never needs to be done after you get your proportions correct (unless your are growing). The 4 moves only need to be done once in the thirty second window.
3. Joycons are really, really bad. Try not to judge slimevr on its tracking fidelity after using just joycons. Its the bottom of the barrel in terms of IMU performance.
4. 5 slimes are needed, minimum, to track lower body. It wont work with only three (for maths reasons)
5. We have regular events if you want to come ask questions or get your tracking ironed out. If it seems like a big scary thing, just come lean on the community a bit! We love new people
^ this
I would like to add that on personal experience joycon tracking is decent with 2 joy cons on each leg + a phone on hips, and I'd say they work perfectly as long as you don't crouch or crawl, any fast rough movement or sitting position that is not a chair will break the tracking, and the wrangler takes a very long time on recognizing the 4th joycon, but it's a nice last resort if you don't have anything else (like me)
I've had problems with firmware updating on diy slimes and the community was fast and responsive at helping me out. It's like the ideal tech support we could only dream of!
I'm not even into VR, I don't have a headset, but now I'm really interested in slimeVR, it looks like a great project, I would love to build them myself and Play around with maybe coding something non-vr using the tech
You can Vtube without VR also so its multiple options, and its "tinkering" :D@@tinolm6202
(1/2) for anyone else who noticed the floatyness in clips like 12:19, that's to do with head/waist lock settings in Vrchat 90% of the time, i had that issue before and fixed it by changing the headlock/waistlock settings, if your slimes have high latency it would be displayed in the server, and would be more likely to present as the entire system going out of sync with itself, like half a leg moving before the other half rarther than the entire system seeming to lag behind together as one, love yall :)
holy shit you've solved like all of my problems ever. i dont use slime but i have crazy floatiness all the time and i didnt even think this would be an issue. i feel like a lot of tracking problems are on vrc's end
Aw yeee, the best bit was when Thrill was like "it's slimin' time" and the slime trackers slimed the best and most expressive they've ever slimed
Amen to that brother
Hi phia@@TheVirtualRealityShow
@@TheVirtualRealityShow hey Phia nice to see you here
Slimebius
I heard this in the Stanley Parable voice
Still surprised that Meta doesn't have its own IMU trackers, it would instantly solve all their leg problems
meta doesn't believe in legs
because meta is a faceless soulless corporation that doesn't believe in human expression
@@bongwatercrocodile315yeah they do?
They just believe it should be expensive. Look at Quest Pro (face tracking)
There doing the ai estimate stuff but it's not as good
Meta is obsessed with inside out. That goes with tracking and the experience itself. They focus on standalone but barely talk about the PC part of VR. They'd rather use headset cameras to track the upper body and make estimates of where the legs are instead of designing some external body trackers.
I have slimes and this is a pretty good overview!
I will say though: once you get your body measurements correctly you never need to do the little hula dance ever again. When your trackers move position you can just do a full reset and mounting reset which are consistent and take about 20 seconds combined. So your extra calibrations after you got it right werent even needed!
The calibration process looks like the Club Penguin dance
I’ve chatted a lot with the community I would say chances are there was some level of inspiration there
You don't need to redo autobone or proportions ever again once your body proportions are correct, even if you mount them differently! As long as they are on the same part of your body, you only ever need to do the full and mounting reset at the very start, which takes all of 20 seconds while standing. Then when you notice drift, which takes at least 20-30 minutes with a lot of physical movement, you do the yaw/fast resets which is done in like 3 seconds. And when you do the yaw/fast reset, you do not need to stand up in a t-pose or recalibate your VRChat avatar tracking! You can do it while standing, sitting, or laying down, as long as your torso, arms, and legs, are facing the same direction as your HMD.
Just have a shortcut button and yaw reset takes just a double tap on B button , super fancy when dancing and need to yaw reset ;)
@@Snitchie you can also tap the chest tracker twice with the new updates.
yes, but still faster using thumb then raising hand and tapping chest ;)@@louie365official
god i hate being broke
oh god that tip...... where you plug it in THEN turn it on.... you've just saved my life.... I've been struggling for days since I moved *sobbing*
The Wii controllers used IMU based tracking, and there is an IR camera in each controller that is used to re-calibrate the controller position using the sensor bar as a fixed reference point. The distance between the lights and the angle of them give the Wii remote the info it needs to find its position. We could probably do something similar with a camera looking towards the slime trackers to re-home them when they come into view to automate the calibration process.
In theory that should work. Most headsets with inside-out tracking basically work like that: their controllers have lights on them in specific patterns that are easy to recognize on a camera (usually IR LEDs which emit light that's invisible to the human eye, but visible to the headset's tracking cameras), and whenever they're within view of one of the headset's cameras, it can automatically recalibrate the position.
@@IkBenBenG With my reverb g2 at least, I think it only has a gyroscope and inside out tracking but no IMUs.
Unfortunately, tracking an object with cameras is hard and inaccurate, and would require a ton of development. You would also need at least 2 cameras in different (known) locations both looking at the same object to obtain its position in 3D space.
What i want to know is if you can use a wii remote as a slime tracker
thats actually a great idea
People who have line sight trackers like Tundra or older Index can use it to help fight the drift once we have users developing a solution.
You don't need to do the autobone/automatic proportions dance each playsession, because people's body proportions don't change. Only the automatic mounting calibration needs to be run each time, which only takes a second (the one where you squat).
So no hula dance necessary, once you get your proportions down to your satisfaction :)
I’m an XR developer and XR/IT support agent. Seeing you admit, your struggle really resonated with me and make me feel a little bit better about when I get a little “five headed “. I’ve never heard that term before.😂🎉 this looks like a great solution and I’m glad that you’re sharing it with us. Thank you so much.
If the 16 dollar chinese trackers actually work fairly well, it's going to take VR chat into the future overnight.
I ordered a set that looked just like that on Amazon and never received my package. I looked into it and it appears I got scammed.
Just tried them, they needed serial to usb patch bc they used counterfeit serial chips. I can't complain for what they are tbh.
@@FAKEAXISwhat are they called
Awesome video on an incredible technology! Great editing and presentation.
SlimeVR has improved dramatically since the last video you did on it, for sure. There's things regarding setup and autobone that still need to be tweaked (autobone can be just wiggling around as long as the heels are planted according to the dev who made it, and animations will be added for simplicity), for sure, but overall it's way better than back then - that flashback sequence made me laugh, as well as the Level 99 Autobone bit (I got assigned that role in the discord server!)
This is really giving me a nudge on showing all the tips and tricks I know about SlimeVR, so thanks for that - I really want people to have the best experience they can with these!
Much love to both you and PHIA!
Always happy to see you being so engaged with SlimeVR. Much love!
woah, wild to see your name again, hope all is well
but yeah this video was awesome
still super excited for my trackers .... well when they ship ;~:
The wiggle dance killed Z
@@a_british_lass_stream_archives I just saw this now, but yeah! I'm doing good, I am actually working on my first commissioned avatar based off of Deira! It's very cute, kind of a gothy build.
@@ZRock35VR oh thats brilliant, i still need the funds to comm a avatar from scratch of my sona, unsure if you've seen her or not, it's been months my memory is foggy
I just finished building mine a few weeks ago and I love finally being able to MOVE! They work pretty well too! 😊 Glad to see you revisit slimes and talk about them again!
Yippee the slime revisit! Ordered mine during the initial crowdfunding campaign and I’m so excited for when mine finally ship home. I’ll finally be able to join my full body friends in VRC and stare at a mirror all evening lmao
Great video! Thank you for testing these thoroughly
I've been using SlimeVR (via phones) for about 2 years now, and it's been amazing! There are some downsides to it, like how often I have to recalibrate, but overall, I love it! Thanks for the new video, Thrill!
Nice video. I’ve been waiting on my trackers for a couple years but it’ll be worth the wait. The devs have been very open and honest with all the issues they’ve encountered. Thanks Thrill!
Excellent video, so glad to see a revisit to the SlimeVR trackers!
I ordered Slime VR (7+3) in March '22
Original Shipping date was the end of August' 23
First delay to end of September '23
Second delay to November' 23
And now with the last post update they got delayed to the end of December '23
I am a very patient person, but if it gets delayed one more time, I'll cancel the order...
Yeah, that my experience with Slime VR so far 😢
oh i already canceled it and made my own. got a 3D printer and the parts for literally the same price, but now i can learn a thing about them, got a free printer bascially and am able to fix whatever breaks. DIY slime is the way.
Hey, you still blame developer for unseen problems like FCC and Corona? You didn't even look around how many people are happy with SlimeVR? Then you should have more trust and patience. They even found new problems and make them even more better. You will get improved version at least.
@@mrdummy_nl uhm, where did I say anything bad about the developer???
I am keeping the order mainly because I got other projects to tend to, and Lynx R-1 is still being shipped out in batches.
@@mrdummy_nl are you okay?
like any other full body tracking method, it’s a bit wonky, but I can’t lie. The open source nature of it is insanely cool
YAY FINALLY VIDEO IM SO HAPPY
every video is a BANGER
It would be cool to merge slime tracking with an xbox kinect. It can roughly estimate your position in 3d space, so it could be a continuos calibration.
You could probably use the FaceID sensors on an iphone to get better accuracy. It's sad that no other phone brands have implemented a similar sensor.
Edit: Actually, I looked it up and apparently the company that made the sensor for Microsoft was bought by Apple, who used it in their FaceID sensors.
Really good review, im really happy that you stay transparent in this video.
I really like the quality of Thirlls videos, he goes into so much detail and cares so much. 😂
You’re the GOAT thrill ! Thank you for the update 👏
Yo thrill i appreciate you using part of my video about my old phone full body .You're amazing
That crazy part is, I know someone (you actually showed them at 11:13) that is working on a next generation prototype using IMU's that are newer then the retail SlimeVR trackers that are newer, that is exciting.
What is also interesting is the failed units you have. The same said person I mentioned above constantly gets completely faulty units they must discard.
The slime knows where it is at all times. It knows this because it knows where it isn't. By subtracting...
I built my own Slime's over a year ago and I still use them. Im actually getting ready to upgrade the IMU's within the week. But All in I first built mine for less than 50$ and I couldn't be happier
I'm so happy to see slim get this huge upgrade and stable tracking, i hope everyone can get them and enjoying it, have a nice day people! 🤗
The SlimeVR setup wizard is nautical miles of a colossal improvement for ease of setup, but the calibration is still per-person and too specific, so the product is not great to share the Full body VR Experience with a family member, friends, at a convention, etc
SlimeVR deserves to become the king of accesible FBT, but they should keep working on that setup wizard, and turn it as plug-and-play as possible
i have close to 7k hours in VR but i could never justify buying trackers and everything just for FBT (ive only used oculus headsets), this gets me very excited for the future of FBT im glad you covered the good and the bad.
They need to make all in 1 suits for tracking and vibration and stop this nonsense of strapping together 8 units. They can make different tier suits for preffered price points, medium priced being likely most sought after.
Man that preview at the end of your video has me hyped! I cant wait to see what you created
I was an early buyer of SlimeVR, over 2 years waiting for mine so I DIY built 2 sets in the meantime. They're pretty great but the better IMUs in the official Slimes are something I'm looking forward to
Ooo! Exciting, I'm definitely gonna solder up a handful of these and give them a spin, I even have like 90% of the components in stock, I'll just have to order the unpopulated PCBs.
Another great video. Thank you
Vive made an Instagram story that said something was going to be announced on the 28th. It had a digital outline of something that looked like the inside out tracker. I’m pretty sure that’s when it’s coming out in a couple days. I’m definitely going pinky up into that. So you’ll have to throw those in your comparisons as well!
Calling them inside-out trackers doesn't really help distinguish them from existing Vive trackers as those are also inside-out.
Better to say markerless inside-out vs marker-based inside-out, camera-based vs photodiode-based, or camera-based vs lighthouse-based.
I am very sceptical of marker-less inside-out trackers for FBT. Each tracker knowing where it is in space isn't enough for FBT - they need to know where they are relative to eachother and the headset.
That relies of them all seeing the same parts of the room and sharing "landmarks", or seeing the headset, or the headset seeing them, or each tracker seeing (and somehow being able to recognise) at least one other tracker.
The Quest Pro trackers that work in the same way reportedly exhibit some weird behaviours and problems and they have a clear view of the headset most of the time. Something attached to your feet doesn't have that luxury.
I'd expect HTC are going to market them more for tracking a single arbitrary object like a camera for the purposes of virtual camerawork.
@@zig131 it's definitely an interesting problem that I can't wait to see how they plan to address. My best guess is that there will be something like a calibration paper or tag which you would point all trackers towards and they reference in relation to that, but it still wouldn't solve the issue of misalignment with the headset itself
@@zig131 Yeah, that's just me misquoting HTC's words "Self-Tracking trackers. I don't really know what you're going on about in the paragraph, not that tech savvy. However here's some words from what looks like one of the people working on it.
"1 dongle for 5 trackers. All 6dof uses IMUs. It’s just easier to use. Much more accessible. In an ideal environment, inside out HMD tracking is as good as SteamVR. We built the new self tracking trackers so there’s a solution to tracking outside the FOV of the headset, without needing external sensors or base stations. Remember lighthouse is still limited to 10m*10m."
Hope that helps.
Hello Thrill!! Thank you for your contributions to the VR Community!!!
Great useful video. Thanks!
As someone not in the slime community, but with Both 10+6 slimes, and 3 vive trackers, I can say this is a fairly accurate comparrison. Personally, I still use my Vives more often, because there's less trackers, though i will say the slimes are more comfortable (they're so much lighter and thinner!). I've added just one slime as a chest tracker to my daily use setup, and that works great. It wouldn't take many more to add arm tracking, but trying to get everything set up absolutely can be a hasstle.
I also want to note that I didn't have any issues with any of the 16 of my slime trackers, at least, that i've found so far.
As Thrill noted though, the biggest issue was setup time.
When i got my Vives for the first time, I was already in VR, and it took maybe 15 minutes to get them up and running, including a mute friend of mine walking me through the in-game settings for my first time in full body.
When i got my slimes, it took me maybe an hour to pair everything and get the setup done. I then spent another two hours messing with calibration trying to get it to a nice place so it doesn't feel messy (and sometimes it wanted to be sideways, which was very weird, but i fixed it in the end).
Now that both are set-up, It really does come down to a preference of lighter weight and no occlusion vs time to put them on, and i am a lazy fucker at times.
Overall, I can and do thoroughly recomend them to basically anyone. They're definately worth it.
I am so excited for when I DO finally get my SlimeVR but yes, I have had them preordered since December of 2021 lol
You’ve convinced me I’m buying
oh wow that teaser at the end though!
Not sure what are the odds but I built my own 7+3 and they just worked first time🤪. I had spares too. Followed instructions and never really soldered b4. Followed UA-cam guides to solder correctly. After the last update its worked great! Highly recommend DIY.
Thank you! This is cool!
Thank you for addressing the shipping problem If I had known that it was going to take so long I would seriously re contemplated other options. I order mine march 19 2023 and I’m personally estimating that they may arrive around jul of 2024 hopefully
Building myself a set of Frozen Slimes V2 right now, can't wait till my parts come in.
I’ve been with the HaritoraX for a few years now, and it’s worked decent to pair with the Quest and not need to worry about basestations. I’d love to move to something with far few cables and wires though, it’s easy to get everything all tangled up haha
I have built mine on the BNO085 IMU with the mag it autocorrects and is perfect.
Loved the RuneScape reference about level 99
An exoskeleton that measures joint deflection is another FBT option. You could also add large feedback systems to such a thing as well.
woohoo lets go new thrill video on slime trackers!!!
My pre-order of slime was November 5th 2021. Alot of delays, but I'm hoping that when they finally do come. It'll be worth the wait.
UA-camrs who timestamp sponsors are underrated immediately.
A slimevr video literally a day after I start planning to build some, amazing timing lmao
Fantastic video, great detailed, unbiased information! Any word on the new self-tracked Vive trackers?
so awesome. I'm really considering buying these, the price for the quality feels like a steal.
NEAT!
Also I love the creepy outro. Is that like a glimpse at the next episode? very neat
I'm genuinely considering it. The prices seem fair for the quality and the quality looks pretty worth it by itself. Glad to see Slime coming back again
If you're ok with some waiting time (all actual orders are planned to be fulfilled by end of April so not so long to wait anymore), it's definitely worth it, especially if you don't have base stations!
@@naomie2680 Thanks for the confirmation! I've been stuck on VR Chat for a while now, so I think I might invest in it for the craic, it helps that I don't need to buy base stations alongside them-
I ordered some diy slimes off the marketplace in the slimevr discord and they got delivered in under a month. They use slightly worse imus (BMI160 compared to the BNOs in official slimes so more drift) but the tracking quality is insane. With 11 trackers its so hard for my friends or most people to spot the difference between me and vive users. Love this project thanks for covering it again
Definitely excited for good and cheap tracking
another banger of a video
I like this. Thank you
I ordered slime trackers this year on the second of january and I'm excited to know that they will be quality trackers :]
i ordered a slime about 2-3 years ago - i still havent got it but im so hyped forit .....
The updates are great and consistent.
I just realized I've been waiting for my SlimeVR trackers for over 2 years, kinda forgot about them tbh
I NEED that autobone dance to be made into an animation that I can put on avatars, it looks too funny
Yep, ordered in Q1 2022, still waiting, now hope to have them in Q1 2024 but hard to keep hopes up just to waiting for the next delay update to come down the wire.
never thought i would see my trackers in a Thrill video even if its for a few seconds xD
The slime trackers shipped again today! They were held up in customs then reviewed by the FCC and had to be recertified and reshipped but in theory they should be out to backers soon.
They also contracted with a manufacturer to get faster and more consistent boards built. Fingers crossed this makes everything from shipping to QA more reliable.
They're really good at updating us on the Discord server
The trackers arrived just over a week ago.
I got the set with 5 trackers and 3 extensions. Chest extension to waist tracker, thighs, then ankle trackers with extensions on feet.
The good: Simple to recalibrate just stand feet close together facing forward and double tap the chest piece, surprisingly accurate tracking and people can't tell it's not vive or tundra, doesn't need lighthouses so they're portable, straps are comfortable, AMAZING BATTERY LIFE VS COMPETITION.
The annoying: Initial setup takes longer, if smaller straps for extensions shift I need to recalibrate, needs more trackers for the same amount of accuracy, if a tracker gets turned off by mistake I have to take them off lay them all flat and reset them.
Recommendation: Go with the full set and don't use the extensions. Still cheaper than a pair of lighthouses with the other trackers and you have greater movement range around the house due to not needing the base stations but if you already have the base stations go with Vive or Tundra.
hahaha i bought these like months ago and still havent got them but im being patient and trusting in you guys
I also ordered slimes almost 2 years ago. They haven't started my shipment yet . I don't doubt the capabilities of the trackers but you should probably wait for them to catch up on orders before investing.
Ive orderd my set if 8 slime trsckers in october and im just excited to even be able to see em
cool to see my world at 12:42 lol
Building mine was fun as hell!
(7:20) FINALLY I KNOW HOW TO DO THIS PART, I was touching my feet with only one hand and was wondering why it thought I was like 9 feet tall. THANK YOU SO MUCH!!!
So tempted to sell my VIVE trackers and base stations and just build Slimes.
VIVE trackers are just so hard to set up in a way where they will give you even decent tracking.
Man if I actually played social games and liked talking to people these would be awesome
I preordered my SlimeVR 2 years ago. Hopefully I will get it next year. =)
I'd dig into that DIY path, building stuff is way more fun that fighting customs for international shipping xD
As a VR dancer and content creator coming from 10 months of using camera tracking to BMI160 14 points! To now BNO085 IMU's all DiY. I have landed on 12 points as the golden point, the neck completes the chest (chest+neck = 1 vive chest, waist+Hip = 1 vive hip).
I only do porportions once (got tutorial on it), since u dont grow ;) Also highly recommend straps with rubber on the inside (Trilancer 12'
I look forward to seeing your review on the $16 trackers! xD
*Interesting stuff, I delivered a Full Watch!* ⭐😃👍
I guess what I wonder is that being an IMU based device, how does it handle abrupt moves? Say for games like Beat Saber where you might abruptly change angles on your wands or controllers? Cool that a much cheaper tech is beating on the big boxes. Reminds me of when we needed pretty solid PC's to emulate systems like MAME or the various Nintendo emulators. Now it can be done with cheap, easy to source Raspberry Pi boards that take no space, little power, and gives us full emulation on even somewhat demanding 3D games. And open source to boot.
Excellent presentation!! Makes me want an upper set of Slimes for the arms and head to emulate hand motions for drone control and head motion for camera panning during flight.
I’m excited for the game!
I love following the technological advancements with full-body tracking, but I have no reason to buy any cuz I’d never actually use it 😭
I certainly can say since I have experience. It will take them a long time to get you the trackers. There is a high demand and very little supply. They doing the aseembly all by hand so there's a limit to how many they can push out. I waited 2.5 years for my trackers.
Vr just keeps getting better. Hell yeah
Where should I look to try and set this up with some joycons? I have like 4 laying around and 1 of them has a broken joystick, so I might as well put it to use.
To me, the most important thing is I think IMU based tracking will be the future of VR. Not as it currently is, but Pico is working on IMU tracking, Valve is working on IMU tracking, even meta if I remember correctly is working on body position estimation with no or almost no tracking. Laser solution definitely works best, but they're a goal, it won't move further from there. At some point I do believe IMU's will reach that point.
By the way, magnetometers (included in the IMUs) can be used to completely negate the drift, but you need a magnetic free environnement which can be hard to achieve sometimes
Was thinking of building my own Slimes soon :3
I've got my parts on the way, and with the amount of electrical parts I have laying around, 6 trackers only costs me about $110 USD.
If you've got any experience with electronics and parts lying around, Slime might be even cheaper and easier for you than anything else.
You know it's good when the video ends with a presentation in Cybertronian
The power of open source! I want more people to see this so they can understand what it trully means for communities and customers to get a mature open source hardware and software and invest more money in such projects :3
I only have issues with 8 point calibration. But that's because it doest say what the calibration settings actually do, and I mean in the documentation. I'd appreciate a little graphic showing like a 3d calibration skeleton or something intuitive to wrap my lil brain around. I gotta say tho, with my diy slimes I've lasted like an hour with only needing a quick reset. Pretty good, better than I expected actually. I also had an imu die, but I think I shorted it soo... 😅 not quite sure, it shows up as good but doesn't track. Well worth the money regardless if u don't mind fiddling with it a bit. 💙
6:57 look at him do his little runescape dance
