Apparently I'm filling my paternity leave by working on old theory/comp neuro ideas I had while in academia but didn't have the time. Now I have research assistants (Claude + chatgpt competing for attention) to help me out

It turns out my humidifier is trying to kill me I got an air quality monitor and notice that the small particle pm2.5 count was reaching "hazardous levels" when the humidifier came on with tap water... but stayed totally healthy when I used distilled water

I just got an air quality monitor, so obviously all I am doing is refreshing to check if I am about to be poisoned

With the upcoming book launch, I wanted a webpage that I am proud of, and @stellatecomms.bsky.social delivered in spades. But not just - when the opportunity arose to partner on #SciAdvocacy efforts, they sponsored this for us all: www.nicolecrust.com/advocacy @caitvw.bsky.social and team!d

Screw good coffee - what's the SF coffeeshop with the best vibe? I'm pretty convinced that all the places I used to go pre-COVID don't exist anymore

What makes fish fast? Can we design robots that make use of designs found in nature (biomimetic)? -> this article claims that the rough shark skin is more efficient, but it also compares it to the smooth skin of fast tuna or swordfish. So why don't they have rough skin?!

My kiddo has shown an interest in learning to read - but is not very interested in those "beginner reading" books. I've been using @midjourney.bsky.social y every day to generate a new "page" of a collaborative book we've been making together

I always found this paper kind of nice: www.science.org/doi/10.1126/... it shows that if the environment fluctuates then evolution will favor sensors and the mutual info between sensors and env increases fitness. If the env has memory, I suspect organismic memory will provably be selected for also

8/ And and that's not all! Here's another large dataset we just released - emg2pose - focused on hand pose estimation using sEMG. emg2pose has 193 participants over 370 hours & >50 behavioral categories w/ hand motion capture ground truth. arxiv.org/abs/2412.02725 github.com/facebookrese...

7/ Our baseline model built using standard techniques from the Speech Recognition literature shows that, with some personalization on top of a model pretrained with 100 subjects, we can quite accurately enable typing with sEMG, eventually without a physical keyboard.

6/ Towards that goal, we now release emg2qwerty - a wrist sEMG dataset collected while touch typing on a QWERTY keyboard. With 108 subjects, 1,135 sessions, 346 hours, and 5.2 million keystrokes, this is quite large by neuroscience standards. arxiv.org/abs/2410.20081 github.com/facebookrese...

5/ But can we further push the boundaries of what is possible with sEMG? We imagine many other applications for sEMG, including the ability to manipulate objects in AR or write full messages as quickly as—or faster than—typing on a keyboard, with very little effort.

4/ And at Connect 2024, we showed how one can use an EMG wristband with Orion—our AR glasses product prototype—for seamless and comfortable control over digital content to swipe, click, and scroll while keeping your arm resting comfortably by your side.

3/ Earlier this year, we unveiled a wristband device that can be seamlessly worn, non-invasively sense muscle activations in the wrist and hand via surface EMG, and achieve out-of-the-box generalization across individuals for multiple tasks including handwriting!

2/ The papers - emg2qwerty and emg2pose - are accepted at NeurIPS 2024 Datasets and Benchmarks Track. If you’re in Vancouver next week, drop by our posters on Fri Dec 13 at 11am PST or at the Meta booth. We have some cool demos to show too! neurips.cc/virtual/2024... nips.cc/virtual/2024...

1/ We just open-sourced two large wrist electromyography (EMG) datasets - one towards typing without a keyboard and the other for predicting hand poses - with baselines. We believe these will help advance research into making high bandwidth non-invasive neuromotor interfaces a reality!
