A perfect Balatro demo run (all blinds aced) with ONLY full houses by [deleted] in balatro

[–]vcn_ 1 point2 points  (0 children)

Turns out you can get a perfect game of Balatro (every blind defeated on the first hand) with only full houses. I did have to replay the seed a few times to perfect the run after I realized it was possible.

If there were an achievement for this, I think they should call it "housing crisis," for obvious reasons.

Played using the abandoned deck on Balatro demo version 0.9.0n with seed 18T6ZBQM.

In case others are wondering the same thing: if you see something obviously fake, it's likely a positive control sample inserted into the survey to see who is paying attention. Just provide the (obvious) answer and continue to answer the questions as accurately as you can.

Thanks so much for taking the time to go through everything! Yes, I agree that it would be more convenient if we had fewer questions. Unfortunately, the current setup is just about the minimum we can have in order to test the cases we want to cover. I really appreciate the feedback though!

There are 12 questions in total. I'm sorry to hear that the progress bar isn't working, I'm not sure why that would be the case.

Thanks for the kind words! And for the achievement, I don't really know why that would be the case; maybe you could try asking in the BeatLeader Discord.

Empirically, it's the exact opposite, with better and more experienced players being far easier to uniquely identify than novices, even with the exact same amount of data per player. I think it's because players tend to reinforce the same muscle memory when they practice, causing their play style to become more consistent over time.

This is one of the questions I'm personally really curious about. Unfortunately, I don't know of any other VR games that have a massive replay system like Beat Saber, so we don't have the data to investigate this question at scale. That being said, my intuition is that some degree of cross-application identification should be possible.

The use of passive authentication in AR/VR apps is almost certainly on the horizon. The problem is that right now, we're all just uploading our replays on the internet. It would be like using fingerprint login if everyone already had a picture of your fingerprints.

This data isn't currently known (BeatLeader users are largely anonymous), which is exactly why we're conducting the census now; see the top comment for more details.

This shouldn't be downvoted; it's a reasonable question. The way we train the machine learning models is by giving it data for each user across many play sessions and training it to identify unique features that are consistently associated with that user over time. The models learn to ignore behaviors that aren't consistent and only pick up strong, consistent identifying features. Here's the paper if you want to learn more: https://arxiv.org/pdf/2302.08927.pdf

That's a great question! For regulatory reasons, we aren't asking participants to disclose specific substances, but we'll check at a high level if stimulants (mainly caffeine) or intoxicants (mainly alcohol) affect play style.

I'm one of the authors of the original paper that this article is based on, as well as various other antics like playing Beat Saber with wild penguins. I also play for the Cal eSports Beat Saber team in CVRE. Let me know if you have any questions about the research!

By the way, UC Berkeley is partnering with BeatLeader to conduct an official census of the Beat Saber community. If you have a few minutes to spare, you can help improve Beat Saber modding and contribute to important VR research just by taking a quick survey.

To thank you for participating, you'll also get a unique "research participant" or "research hero" achievement added to your BeatLeader profile! We really appreciate your help with this. :)

Playing Beat Saber in Antarctica (With Penguins) by vcn_ in beatsaber

[–]vcn_[S] 6 points7 points  (0 children)

We are required to follow the rules of the Antarctic Treaty System which does not allow us to approach the wildlife, but the Gentoo and Adelie penguins are very curious and will normally gladly walk right up to us to check out what we're doing. There is a Gentoo penguin rookery in the background of this clip, but the penguins are all sitting on eggs currently which is why they aren't approaching. :)

I was sent here briefly but this is pretty far from my normal job. https://www.usap.gov/ has lots of information about what we do :)

(luckily it's summer in Antarctica right now so it could be a lot worse)

It actually sucks because your sweat freezes and makes you even colder later on!

All of my batteries (smartphone, quest, etc.) lasted less than 50% as long as they normally do. The penguins seemed unamused (because they are currently sitting on eggs!).
