VR Juggling Simulator

Built on Tracking Data
The VR Juggling Simulator is powered by tracking data from my juggling dataset. Each juggling pattern in the simulator is based on .csv files that contain the positions of the balls in video clips. The simulation animates the balls by moving them to the positions specified in these .csv files, creating a realistic visualization of juggling patterns.
Trying It Out
You can try the VR Juggling Simulator by downloading the APK file. I installed the app on my Quest 3s headset from my Linux computer using a tool called ADB.
Copy and Paste
This project involves a significant amount of repetitive data handling. The simulation includes approximately 100 juggling balls, all of which are continuously animated. Due to the complexity and resource demands of the app, the Quest 3 tends to get noticeably warm after running it for a while.
Features of the Program
In this app, users can explore juggling patterns in an immersive VR environment. You can walk around and observe the patterns from different angles or use the thumbstick to move through the space. However, there is currently no interaction with the environment—it's purely a visual experience.

Thanks Stephen. I've always been interested by how VR/AR can enhance the learning of juggling. The idea of 'being there' in a 3D environment with a pattern, slowing it down, and gradually increasing the speed to really get a feel for it before actually making it physical.. it sounds like a useful tool. I'm excited to check it out later - hopefully, it’s compatible with my old Quest 2? Best of luck with the project!

How did it work on your Quest 2?
If you are looking for more VR juggling stuff...here is a link to my first VR juggling video on Youtube.

Cool simulator. What I have always wanted would be a club passing game, so you could pass clubs with people from around the world in VR.

Thank you!
The algorithms very much want me to buy one of these 'high-tech' magic flying balls. They look like the kind of thing that's sure to break within a few days, but I do wonder if they could be juggled? Has anyone tried one (or preferably three)?
I found a pair in a charity shop maybe a year ago and like you thought they would be very interesting to juggle, so bought another two on-line. They were only £5-6 on-line (or £2 second hand) then, you might be able to get them for less than £15 still.
Trying to juggle them is very exciting, they are lightweight and have almost no incentive to stay upright. Any deviation from upright causes them to go suddenly sideways and you are chasing them across the room like a stray bounce juggling ball.
I plan to try adding a small weight to the bottom to see if that keeps them more vertical without damaging lift, but haven't got round to it yet as there is only limited space in my juggling bag. They look as robust as you might expect a disposable child's toy, they also fly different heights depending on how recently they were recharged - from memory something like 5 mins flight after 15 mins charging.
I might try to bring them to Leeds convention on Saturday if I have space (and can remember where I put them).

Thanks. I suspected they might not be as stable as they appear in the various advertisement videos. Interesting that you thought of modifying them.. I'm curious to see how that turns out!
Having just made some cheap ball pit juggling balls for some workshops I have weighted my normal Play Sil-X Light (I think) balls (just to get a weight to fill the self made balls) and noticed more variation on the weight than I would have expected. (In case you don't know this balls, this are hybrid balls with a soft shell and a silicone oil as filling - not as much dead drop as russian balls, but maybe a bit less wobbly - tastes on those diverge, for me this are my favourite balls). Now those are several years old and while I always thought of them as pretty tight and wouldn't expect them to leak I can not rule that out entirely. Also they were bought at different years and while they *should* have been the exactly same ball I also can't rule out that Play changed the fill levels (The weight table on their ball configurator page has different weights than I remember from some years ago).
Has anyone experienced that as well? Does Play sell silicone oil for refilling and has anyone tried this? Or does anyone know which brand of silicone oil they use? I think I have seen some video some years ago on how to remove the plug and that should probably not be a problem I think. Unfortunately they don't do the juggling convention in Imbersago (Conventions di Giocoleria della Brianza) anymore where I would have asked them directly ;). I miss that convention.

The last set I bought (from Oddballs) were different weights. They kindly took them back and replaced them with new ones that were an identical weight (108 grams).
, , , , Thought Of The Day
This morning, I went to the baker's and I said: "Hey, that looks really good, how long have you been baking?"
Then, at the butcher's: "All looks great! How long do you butcher per day?"
On my way, I passed a hatter's shop, went in and said: "Great work, Sir! Keep on hatting!"
I wonder, if these people sold anything and if they can make a living of their awesome work!

I was one of those that started sourdough baking at the beginning of the pandemic. It's really quite satisfying and, although some seem to be better than others, generally the bread is delicious. I can't remember the last time I bought some bread!
Westminster council are picking on Covent Garden buskers again, as they do every few years.
https://youtu.be/nWLg9d16Vm0
(Gets to the point at 7m35)
There's a petition at www.savelondonbuskers.com
Well worth watching the video.
Signed the petition, I don't think many more needed to get over 5000, although I'm unsure because if you load the page the signature counter ticks up. Reload the page & it starts again at the same number?
new to me. an open air alltime streetcircus, it seems (maybe not when it rains). hardly ever seen a place with several buskers \ streetperformers at the same time - maybe in front of Centre Pompidou; there must be more places like this over the world, I reckon .. Melbourne?, Seattle?, Central Park, New York?, .. dunno.

Edinburgh is boss town during the Fringe Festival.
pumpkineater23 - - Vorredner #
Street performance still seems alive and well here in Brighton as far as I can tell. The area around the West Pier has been buzzing with musicians, jugglers and skateboarders etc..

Wow - If I am not mistaken, Jim was busking at Covent in the early nineties. I worked the More Balls stall for about a year there. The buskers were the centre of attraction. It would be sad to see such a great tradition come to an end. Performers were fully miked up in 1992 and that's the way it was- and is. It would be like moving to a flat 2 blocks from Niagara Falls and then complaining about the mist. Cherish it!
Re-starting juggling meetings after lockdown, what precautions should we take?
We stopped meeting for juggling in March, but we have now been told our juggling venue is open again though with a few safety rules and a limit of twenty people.
We have been trying to think of what extra safety precautions we should take to make sure juggling is as safe as possible. So far some of the ideas we have come up with are:
Has anybody else re-started their juggling meetings or have any good ideas of other precautionary measures we could take?

Apparently, humidity can play a huge part in the transmission of COVID19. The droplets instantly become heavy when the air is wet, and fall to the ground. They hang around for far longer in dryer air. Both heating and air conditioning dry the air significantly.
The elephant in the room is will you allow passing?
Is it really a club meeting if you can't pass?
el_grimley - - Vorredner #
For the Wellington club we don't allow passing under our level 2 lockdown in NZ. Solo is fine. No juggling clubs allowed for level 3 or higher.
Level 1 is back to normal.
One more suggested caveat - Don’t feel obliged to come if you are afraid or don’t want to use public transport.
I have submitted a risk assessment to our landlords,I have said that passing not allowed (initially, am hoping to introduce) unless you are in each other’s social bubble. Keeping details for track and trace and making sure everyone who comes agrees to this. Subs must be paid online or in exact money, kit bags spaced around the hall and we have max numbers that can juggle at any one time, no sharing of equipment ( unless already ina a bubble with each other). The club will supply hand sanitiser and wipes that I will absolutely not be stealing from work. I have offered to do temperature checks if the landlords want but it doesn’t really have any value. Strict it rules for opening and closing the hall. Haven’t heard back yet but fingers crossed for September.

I'm not sure the jury's totally back in on whether temperature checks are useful or not. The real question there would be cost based unless you already have access to an IR thermometer etc. I suppose you could insist on rectal thermometer readings*, but that might somewhat limit participation.
If you're actually serious about limiting the potential for spread, there is no reason you can't insist on masks.
* rectal or under-tongue readings are pretty much the only ones that you can rely on. You can use the same thermometer, the only difference is the aftertaste.
We have restarted juggling meetings in Tübingen, germany, when it was allowed.
However we are still juggling outdoors (as far as the weather permits - also I should update club information here on the edge and on the webpage - we are in fact meeting again). We are about to start juggling indoors again soon, so it is interesting to read what other people think.
We follow all the rules you have written (we don't have a tea mug rule... nobody drinks tea here before / after juggling yet ;)) but we allow passing patterns for the people who like to do so (which are the same close group of people everytime, so if there is a spread it will be kind of limited).
As far as I know the risk of transfering Covid via objects is fairly low* and not the main infection path (which is via droplets and aerosols) and it can be lowered even further if everyone uses hand sanitizer before and after and does not touch his face in between.
Still - with passing manipulation patterns one does get closer to other people so it is of course a higher risk than juggling alone standing apart from each other. On the other hand one is then constantly changing position so it is less bad than - let's say sitting next to each other in a restaurant where there is no air movement and critical virus concentration can be reached. As far as I know the german contact tracing app only registers close contacts with a time of over 15 minutes.
Maybe interesting are some rules in germany for indoor training (this is specific for the state of germany I'm in, Baden Württemberg... other states have similar but different rules), of the top of my head:
+ If the sport is contactless (solo juggling) there should be at least 10 square meters per person
+ If there is the possibility of some contact situations there should be at least 40 square meters per person
+ Maximum number of people in group is 20 (but there may be more than one group if the facility is big enough)
+ One needs to make sure a distance of 1.5 meters is kept, also when using showers or toilets
+ If there is direct contact in sport, it should be made sure, that it is always the same people who have close contact (for example in partner acrobatics - which is allowed again - people should not change so much)
+ Contact information for each training session needs to be collected and destroyed after four weeks
*Interestingly it seems to be even lower on rough surfaces which is kind of counterintuitive for me.
We didn't shut down our juggling meetings (except when we thought the gymnastics club we are part of had cancelled our reservations for the gym, that was about 4 weeks in march-april).
The only thing we have done is bring hand sanitizer and a small poster reminding people to stay at home if they have symptoms, wash their hands before and after juggling, and avoid close contact. It's up to the participants to decide what close contact means, and whether they want to pass clubs or not. We are all adults (our youngest member is 17).
The flow club that we share practice space with did cancel their meetings during spring, though, which means we were only 4-5 people there each time, maybe 7 different people in total. (Our club needs more members....)
We don't have tea breaks but usually go to a cafe after juggling. We kept doing that but often ordered take-away and sat somewhere outdoors.
Now things are pretty much back to normal, the flow club is back, we still have the hand sanitizer and the poster.

Durham City Jugglers re-opened on the 8th September after quite a bit of discussion among the club and with the community centre where they meet. The community centre have been following the government procedures and have put in enhanced cleaning facilities, one way systems and installed gel dispensers in the hall and corridors etc.
The club did a separate risk assessment and procedures in parallel to that. As the club is only small and adults we think we think it is controllable. Here are some of the relevant points to this discussion:
ok... first week went well and all seamed good. Then on the 9th September the UK Government announce that it is restricting groups to 6 people.
The UK Government is rapidly updating their guidance and it looks like community activities like juggling clubs are exempt from this 6 person rule as long as they conform with their other guidelines. Here is the main relevant document we believe relates to juggling clubs:
https://www.gov.uk/government/publications/covid-19-guidance-for-the-safe-use-of-multi-purpose-community-facilities/covid-19-guidance-for-the-safe-use-of-multi-purpose-community-facilities
This all seams such a fluid situation that everything is under review, but this is where Durham City Jugglers is at the moment.

The 3Play series is still great. So thanks for those, Peter.
A couple nice words I was reminded of recently:

That's a lovely thought. Thank you Mike.
pumpkineater23 - - Vorredner #
Hey thanks for that. There's so much jugging I'm seeing online.. so amazing, beautiful and many many levels higher than mine, really my 3b is pretty bland and basic by comparison.. but big thanks for your great compliments! It's truly a great time to be around for those of us interested in 3b juggling, there's an abundance of mind-blowing stuff to watch and be inspired by.
I still juggle a little most days and I enjoy it. Playing around with it though, I haven't really been putting any time into serious practice for the past few years. During the 'lockdown' I've been trying to learn 531 with the 3s carried across. It's one I've wanted to be able to do for a while. Finding it difficult to lower the 5s and run the pattern.
I might film some juggling soon and see if anything interesting pops up, and if it does I'll upload it.
Cheers.

That's the one. He's a great juggler!
Marble machine - stick with it, there's juggling of sorts
https://youtu.be/87fzwSqRi88
Little Paul - - Vorredner #
That’s lovely!
John Sheets - - Vorredner #
Yes that's very neat.
Nice! This particular marble machine reminds me of a static poster that someone from rec.juggling designed that had the arcs of different weight throws marked at regular time intervals so you could visualise patterns by sliding coins along the trajectories moving them on one stage at a time. The figure 8 contraption is a working model.
There are some other interesting things on his channel too. Nice to know the source of the rotating open/closed sign that I remember seeing as a viral gif a few months ago.

Love it. I wonder is that something that can be 3d printed?

Ah ha - thank you!
Hey everyone!
Apparently I’m supposed to say hello and a bit about myself, so here goes:
Well that’s about it for my introduction. Hopefully I’ll be posting a regular practice log, which might be motivating, we’ll see :)

Welcome Kyle!
What does more serious (and TOO serious) mean for you?
I would have loved to learn springboard diving, but never found a good club in any of the places I lived. Maybe one day! Oh and I share your disgust for olives ;)
Little Paul - - Vorredner #
Oh good - I thought it was just me on the olives.
I’m told they’re an “acquired taste” but I fail to see why anyone would want to push through that learning phase
That's how I feel about coffee and beer. ;)
Olives, however, I have liked since I was a kid. At least the green ones. Now I also like black olives. (Then of course there are those cheap fake-black olives that some people put on pizzas and in salads... Those are not good.)
I too love olives, especially stuffed with a whole garlic clove or feta. I used to not like them but then I found out it was because I had first tasted the awful fake black ones first.
I also don't understand why people push through the disgust barrier for coffee, & cigarettes! Why on earth does anyone go through the effort required to get addicted to nicotine?!
Look what you've started Kyle!
Danny Colyer - - Vorredner #
I wouldn't have thought coffee was an acquired taste. I loved it the first moment I tried it, anyway.
As I've got older I've found that I like it more bitter. I now have no sugar and only a splash of milk. I can no longer drink instant coffee because, even without sugar, it tastes too sweet.
Beers are hugely variable. When I was a kid I was happy enough with manufactured lager. My first pint of bitter at the age of 19 was a revelation. That was the day I stopped drinking lager.
pumpkineater23 - - Vorredner #
I always loved boiled eggs and hated olives and then all of a sudden I loved olives and hated boiled eggs. It's almost as if some connection in my brain got them mixed up or something.
Daniel Simu - - Vorredner #
I'm with you on coffee and beer! Although I guess I did try to like beer, I was glad to give it up and not look back...
Cedric Lackpot - - Vorredner #
Bloody heretics the lot of you. Except Maria. Come the revolution, Maria gets to live.
I’d say that for me at least, "not TOO serious" means I want to keep having fun with juggling, and not become obsessed with being really good or getting certain tricks just because I feel they’re "necessary." I don’t think that’s going to happen, but I still sometimes like to say it just to remind myself. That’s not to say I don’t want to get better or achieve high goals, just that I'm to make sure I don't lose sight of what’s important to me.
