Alright, first of all: doomscrolling about sleep tech at 2am is extremely on-brand behavior, so you’re among friends here. Short answer?Micro-moveme…

Yep — sleep scores are absolutely a thing in wearables, and spoiler:there’s way less magic in them than marketing wants you to believe. Most “sleep …

Hey, welcome to the IMU rabbit hole.This is one of those areas where everyone name-drops Kalman, Madgwick, Mahony, quaternions… and then somehow skips…

Honestly, it doesn’t really reduce them at all, lol.You still have to worry about windowing, sampling, and preprocessing,but you just don’t see the “w…

I always started with a minimal set. Otherwise, debugging would be a nightmare.The cleanest approach was to create a baseline with something like mean…

Good point. In real-time, that’s the first thing everyone thinks about.Usually, we compromise by setting the window to 3 seconds and updating the resu…

It’s not for nothing that they say you should double-check your window and feature set before changing your model in activity recognition.1. Window Si…

Yes, it does increase the management overhead. So, we usually separate the models, but share the preprocessing pipeline as much as possible. Alternati…

We’ve all experienced that at least once, lol.In my experience, starting between 0.3 and 0.5 Hz and not deviating too much has been the most stable ap…

These questions usually lead to lengthy comments, lol.To summarize briefly, “A lot of things are theoretically correct, but in practice, compromises a…

The location… Honestly, it’s quite large, lol.The gyro is a hidden asset on the wrist, but the acceleration cycle is cleaner when worn on the waist or…

Personally, I felt like autocorrelation worked better.FFT is powerful when tuned well, but even a slight mismatch in the sample rate or window caused …

In short, the key point was, “While cycling may seem similar to walking/running in terms of vibration patterns, their rhythms are different.”1. Don’t …

Exactly. There are many proof-of-concepts (PoCs) that are “just going to work,” but they rarely make it into product lines due to battery life and sta…

Yes, it’s almost exactly both, lol.From the product team’s perspective, they often have to explain “why they decided something this way,” so RF is muc…

In the real world, RF/GBDT + feature engineering is still the most commonly used.Deep learning is “good to have, but expensive,” and Transformer/TinyM…

Ohhh yeah, this is one of my favorite “human signals meet wearables” topics.So here’s the deal: mechanically measuring emotions is not magic, it’s bas…

Okay, bro! The principle behind this self-powered sensor may seem like magic, but it’s actually explained through some pretty cool physics.I’ll explai…

Exactly.We’re pretty much heading into an era where just moving around turns your body into a tiny power plant lol.

lol not yet.Smartwatches eat way too much power—screens, processors, wireless, all that.But patch-type health monitors or basic wearable sensors?Those…

Yep, it’s real. Piezo and TENG tech have gotten wild lately.It used to be “cool lab demo” territory, but now they’re literally weaving this stuff into…

To be honest, self-powered wearable sensors (piezoelectric/triboelectric/TENG-based) are a real reality.And yes, it’s natural to be surprised when you…

Of course it’s important! Medical data is particularly sensitive, so we’re putting a lot of effort into data anonymization and establishing security p…

Oh, Steve Ryu! That’s a good question. Indeed, “recovery” is a difficult concept to define with just a few numbers. However, recent research is active…

That’s a very interesting question! In fact, we can say that the era of “machine learning automatically assessing a patient’s recovery stage” is alrea…

That’s right. Ultimately, the key is content. The hardware certainly seems ready, but I think whether we truly enter the “post-smartphone era” will de…

Exactly. The performance and display specs are also on par with the Vision Pro, so they’re aiming to compete directly. Samsung, in particular, is said…

Yes, most of them will need to be re-optimized for the XR. However, Google is actively pushing development tools to expand its ecosystem, so the barri…

That’s a good question. While the basic framework is Android, the interface and features are completely redesigned specifically for XR devices. For ex…
