WEBVTT

00:00:00.140 --> 00:00:01.362
Alright, welcome back to Tech.

00:00:01.362 --> 00:00:05.533
Between the Lines, I'm Between Two Pixels and I'm here with the one and only Finn Circuit.

00:00:05.533 --> 00:00:12.974
Today we're diving into the wild world of wearables like way beyond just counting your steps or buzzing your wrist when you forget to stand up.

00:00:13.519 --> 00:00:16.126
Yeah, because apparently my watch needs to nag me now.

00:00:16.126 --> 00:00:19.193
But you're right, between these things have gotten a lot smarter.

00:00:19.193 --> 00:00:25.033
We're talking about devices that track your heart rate, blood oxygen, even stress levels.

00:00:25.033 --> 00:00:29.611
Apple, fitbit and a bunch of startups are all trying to outdo each other.

00:00:29.611 --> 00:00:34.432
It's like the Olympics of health tech, except nobody's winning gold for privacy.

00:00:35.020 --> 00:00:37.609
Okay, but you gotta admit the tech is getting seriously cool.

00:00:37.609 --> 00:00:40.069
I actually beta-tested this smart ring last month.

00:00:40.069 --> 00:00:42.768
Shout out to the devs at that little startup in Palo Alto.

00:00:42.768 --> 00:00:45.709
It tracked my stress in real time during a hackathon.

00:00:45.709 --> 00:00:49.090
I could literally see my cortisol spike every time my code broke.

00:00:49.090 --> 00:00:51.749
It was humbling, but also kind of awesome.

00:00:52.259 --> 00:00:54.088
I'll stick to coffee and denial thanks.

00:00:54.088 --> 00:00:56.366
But yeah, the accuracy's getting better.

00:00:56.366 --> 00:00:59.329
These aren't just glorified pedometers anymore.

00:00:59.759 --> 00:01:04.349
And it's not just the sensors, right, it's the AI behind the scenes crunching all that data.

00:01:04.349 --> 00:01:12.108
Machine learning models are spotting patterns, flagging early warning signs for stuff like arrhythmias or sleep apnea.

00:01:12.108 --> 00:01:13.614
It's like having a mini-diagnostician on your wrist.

00:01:14.239 --> 00:01:17.307
Yeah, and sometimes it's like having a hypochondriac too.

00:01:17.307 --> 00:01:25.209
But look, I remember back in the 90s we ran a hospital trial with pagers and these clunky biosensors.

00:01:25.209 --> 00:01:32.153
You'd get a beep if someone's heart rate went nuts, but half the time it was just interference from the vending machine.

00:01:32.153 --> 00:01:36.427
Now you've got AI flagging real issues in real time.

00:01:36.427 --> 00:01:40.320
That's progress, even if I don't trust the black box.

00:01:40.941 --> 00:01:44.945
Totally, the difference is night and day, but like we gotta talk about the risks too box.

00:01:44.945 --> 00:01:46.807
Totally, the difference is night and day, but like we got to talk about the risks too.

00:01:46.807 --> 00:01:48.409
False positives, over-reliance on algorithms it's not perfect.

00:01:48.810 --> 00:01:50.271
Hospitals are all over this stuff.

00:01:50.271 --> 00:02:01.400
Now you see clinics handing out wearables for remote monitoring post-surgery recovery chronic disease management.

00:02:01.421 --> 00:02:03.566
It's not just for fitness junkies anymore, yeah, and consumers are driving a lot of that demand.

00:02:03.566 --> 00:02:06.174
People want to know their numbers Heart rate, sleep, stress, you name it.

00:02:06.174 --> 00:02:10.010
My AR glasses literally show me my stats in the corner of my vision.

00:02:10.010 --> 00:02:13.591
It's like living in a sci-fi movie, except with more notifications.

00:02:14.139 --> 00:02:15.967
And more ways for your data to leak out.

00:02:15.967 --> 00:02:20.330
I mean sure it's convenient, but every new feature is another privacy trade-off.

00:02:20.330 --> 00:02:22.901
You can't have your cake and eat it too, kid.

00:02:23.341 --> 00:02:24.181
That's a good segue.

00:02:24.181 --> 00:02:26.662
Actually, the regulatory side is getting complicated.

00:02:26.662 --> 00:02:31.984
You've got the FDA in the US, ce marks in Europe and a patchwork of standards everywhere else.

00:02:31.984 --> 00:02:37.546
Getting a wearable approved as a medical device is a whole different ballgame than just selling a fitness tracker.

00:02:38.146 --> 00:02:39.387
And don't forget the ethics.

00:02:39.387 --> 00:02:41.087
Who owns your health data?

00:02:41.087 --> 00:02:45.270
What happens if your insurance company gets a hold of your heart rate history?

00:02:45.270 --> 00:02:50.481
There's a lot of gray area and most people have no idea what they're signing up for.

00:02:51.050 --> 00:02:53.318
Exactly, User education is huge.

00:02:53.318 --> 00:02:57.782
Companies need to be way more transparent about what data they collect and how it's used.

00:02:57.782 --> 00:03:01.501
Otherwise, people are just going to lose trust and then adoption tanks.

00:03:02.009 --> 00:03:03.012
So what's next?

00:03:03.012 --> 00:03:09.491
I keep hearing about nanotech and bioelectronics stuff that sounds like it's straight out of Star Trek Sensors.

00:03:09.491 --> 00:03:13.037
You can swallow patches that monitor your blood sugar without a needle.

00:03:13.037 --> 00:03:14.038
It's wild.

00:03:14.580 --> 00:03:17.044
Yeah, and personalized medicine is the holy grail.

00:03:17.044 --> 00:03:22.262
Imagine your wearable learning your unique health patterns and flagging issues before you even feel sick.

00:03:22.262 --> 00:03:30.463
But we've got to solve the basics first, like battery life, durability and making sure your data doesn't end up on some sketchy server in who knows where.

00:03:31.009 --> 00:03:33.838
Right, If my pacemaker needs a firmware update every week.

00:03:33.938 --> 00:03:34.259
I'm out.

00:03:34.259 --> 00:03:36.175
Integration's a big deal too.

00:03:36.175 --> 00:03:42.938
Getting your wearable data into your electronic health record so your doctor actually sees it, not just you, is still a mess.

00:03:42.938 --> 00:03:48.638
We need better APIs, smarter syncing and honestly more user control and personalization.

00:03:49.300 --> 00:03:51.871
These things should adapt to you, not the other way around.

00:03:51.871 --> 00:03:58.633
Adaptive algorithms, custom alerts, stuff that actually makes sense for your baseline, not some generic average.

00:03:58.633 --> 00:04:04.212
But again, security's gotta be rock solid, Otherwise it's just another attack surface.

00:04:04.694 --> 00:04:08.711
One thing I love is how wearables are starting to nudge people toward healthier habits.

00:04:08.711 --> 00:04:15.681
Gamification streaks, personalized feedback it's like having a coach in your pocket or on your finger or wherever.

00:04:16.269 --> 00:04:19.610
Yeah, but you can't just slap a badge on it and call it behavior change.

00:04:19.610 --> 00:04:21.598
You need real science behind it.

00:04:21.598 --> 00:04:28.379
Psychologists, behavioral experts, get them in the room, Otherwise people just ignore the notifications after a week.

00:04:28.920 --> 00:04:30.050
Totally the best.

00:04:30.050 --> 00:04:35.519
Wearables are the ones that actually help you stick with new habits, not just guilt trip you for missing a workout.

00:04:35.910 --> 00:04:39.161
But let's be real, not everyone's jumping on the wearable bandwagon.

00:04:39.161 --> 00:04:45.060
Cost is still a big barrier and if you're not tech savvy, some of these interfaces are a nightmare.

00:04:45.610 --> 00:04:47.418
Yeah, and that's where education comes in.

00:04:47.418 --> 00:04:55.480
Companies need to make these things way more user-friendly, with tutorials, support and feedback loops, so users can actually say what works and what doesn't.

00:04:55.480 --> 00:05:00.041
Otherwise, you're just designing for the same group of early adopters over and over.

00:05:00.041 --> 00:05:08.860
I think the real magic happens when wearables just blend into your routine, like you don't have to think about charging, syncing or even wearing them.

00:05:08.860 --> 00:05:11.358
They're just there working in the background.

00:05:12.029 --> 00:05:23.939
That's the dream, but it takes partnerships, tech companies, healthcare providers, maybe even your insurance company, and the interfaces need to be customizable so they fit your life, not the other way around.

00:05:24.529 --> 00:05:28.442
Exactly the more seamless and adaptive, the better the long-term engagement.

00:05:28.870 --> 00:05:29.831
Let's talk security.

00:05:29.831 --> 00:05:33.855
End-to-end encryption should be the default, not an afterthought.

00:05:33.855 --> 00:05:44.687
If your health data is floating around unprotected, that's a disaster waiting to happen, and users need real control, like easy ways to see, download or delete their data.

00:05:45.235 --> 00:05:46.682
Transparency builds trust.

00:05:46.682 --> 00:05:52.404
Plus, working with regulators to set clear standards is key, otherwise it's the Wild West out there.

00:05:52.404 --> 00:05:58.028
On the big picture side, wearables could actually lower healthcare costs by catching problems early.

00:05:58.028 --> 00:06:01.786
Preventive care is way cheaper than treating stuff after it gets serious.

00:06:02.435 --> 00:06:03.901
Yeah, but there's a flip side.

00:06:03.901 --> 00:06:08.826
If only the wealthy can afford the latest gadgets, you're just widening the health gap.

00:06:08.826 --> 00:06:14.190
We need strategies to make this tech accessible, not just another toy for the privileged.

00:06:14.733 --> 00:06:15.394
Totally agree.

00:06:15.394 --> 00:06:21.528
Tech companies, health care providers and policymakers all need to work together to make wearables more equitable.

00:06:21.975 --> 00:06:25.805
If you want people to actually use these things, you've got to show real benefits.

00:06:25.805 --> 00:06:34.641
Targeted marketing, partnerships with healthcare and insurance, maybe even discounts or rewards for using wearables that's how you get buy-in.

00:06:35.274 --> 00:06:39.086
And we need long-term studies to prove the health outcomes and cost savings.

00:06:39.086 --> 00:06:42.824
That's what'll convince the skeptics and the folks holding the purse strings.

00:06:42.824 --> 00:06:45.141
Interoperability is still a mess.

00:06:45.141 --> 00:06:50.487
We need standard data formats so your wearable can talk to your doctor's system, no matter what brand you use.

00:06:51.115 --> 00:06:57.007
That means tech companies, healthcare, IT vendors and standards bodies all need to get on the same page.

00:06:57.007 --> 00:07:02.785
Pilot programs are a good start, but we need real-world feedback to make it work at scale.

00:07:03.206 --> 00:07:07.882
Design matters too Wearables, should work for everyone Different ages, genders, abilities.

00:07:07.882 --> 00:07:13.423
That means doing real user research, not just guessing what people want, and adaptive interfaces.

00:07:14.115 --> 00:07:17.725
Let people customize their experience so it actually fits their needs.

00:07:17.725 --> 00:07:21.625
Otherwise, you're just building for a narrow slice of the population.

00:07:22.014 --> 00:07:24.204
Last thing ecosystem integration.

00:07:24.204 --> 00:07:30.247
We need universal API standards so all these devices can talk to each other securely and reliably.

00:07:30.247 --> 00:07:32.463
That's how you get real value from the data.

00:07:33.134 --> 00:07:34.562
And it's not just about the tech.

00:07:34.562 --> 00:07:45.887
You need collaboration, tech firms, healthcare regulators testing these systems in the real world, plus a global task force to keep the privacy and ethics guidelines up to date.

00:07:45.887 --> 00:07:48.901
Otherwise, we're just reinventing the wheel every year.

00:07:49.423 --> 00:07:50.447
Couldn't have said it better.

00:07:50.447 --> 00:07:54.386
All right, that's a wrap for today's episode on wearables at the cutting edge.

00:07:54.386 --> 00:07:56.482
Finn, always a pleasure to spar with you.

00:07:56.975 --> 00:08:00.144
Yeah, yeah, don't let your smart ring boss you around too much, kid.

00:08:00.144 --> 00:08:01.086
See you next time.

00:08:01.595 --> 00:08:02.800
Thanks for tuning in everyone.

00:08:02.800 --> 00:08:04.500
We'll catch you next week on Tech.

00:08:04.500 --> 00:08:08.538
Between the Lines, Stay curious and maybe check your heart rate while you're at it.

00:08:08.538 --> 00:08:09.139
Bye.
