MindWalker brain-controlled exoskeleton puts the paralyzed on their feet

An eight week EC trial of a brain-controlled exoskeleton potentially promising newfound mobility to those with lower-limb paralysis will finish this week, with the project expected to spark a five year development path to a commercial version. The device, dubbed MindWalker, is the handiwork of a team at the Free University of Brussels, which has been working for the past three years on a motorized exoskeleton that can be controlled and navigated via brain impulses. Now, New Scientist reports, the European Commission will assess the results, having funded the project so far.

The MindWalker is made up of two companion projects, as the name implies. Arguably more straightforward is the exoskeleton side, which has been designed to support the weight of an adult, keep them balanced when walking, and adapt to different walking styles. An integrated brain in the walker itself helps spot obstacles that could present an issue for the user.

However, more complex is the mind-reading part, which the team refers to as the Brain/Neural Computer Interface (BNCI). A non-invasive system, using a dry EEG cap that doesn’t require messy gels or intrusive surgery, the technology cap is paired with a portable amplifier to make sure the computer gets the right signals. Previous methods have also included flickering diodes that gage intention to move by where the eye pays most attention.

The training process begins before the user has even strapped into the exoskeleton, however. The MindWalker team has developed a virtual reality training package which allows potential wearers to train their brains to get the most out of the BNCI link. As well as creating virtual obstacle courses to navigate through, the training system also includes a motion-actuated seat so that they become used to the sensation of being moved around by the motorized legs.

The dual development means that, even if mind control isn’t suitable for a particular user, that doesn’t mean the exoskeleton itself is out of reach. A more rudimentary control system – with pressure pads on the sides, triggered by rocking within the harness – to move each leg is also possible.

With brain control, though, there’s a lot more finesse up for grabs. The EEG system can apparently differentiate between the aim to move slowly or at speed, meaning pace could be controlled simply by thinking differently. Down the line, it could mean expanding the system to users with even less mobility, potentially including those who experience full body paralysis.

So far, the EC has pumped €2.75m ($3.6m) into the MindWalker project over the course of around three years. It’s still a long way out from commercialization, however, and the estimate is that it will take another five or so before a production version could be ready. By that point, project member Thomas Hoellinger suggests, the system could be a lot more aesthetically discrete, with less weight, smoother movements, and potentially even a frame that could be disguised under more traditional legwear.

The Mood Ring Gets Its Quantified-Self Update With The W/Me Wristband

008e721aebd5a93b20a835da77b82cf2_large

A lot of the gadgets that help people monitor and track their physical health focus on providing feedback related to physical activity for use with tracking workout data and energy expenditure during the day. Now, a new Kickstarter projected called the W/Me band wants to leverage similar data sources, but with the goal of providing a more holistic picture of wellness.

The W/Me wristband is based around a sensor that monitors your body’s automatic nervous system, providing feedback on body activity that you may not be at all aware of, including breathing patterns and heart rate, to let you know about automatic reactions you may be having that are detrimental to your state of health or physical wellbeing. Then, with rhythmic breathing exercises, the idea is that you’ll be able to correct these negative patterns and improve your general health and mood for the better.

The W/Me project is different from most activity tracking in that it takes a very specific goal of managing breathing and describing a user’s mental state. It provides readings for agility score and ANS (autonomic nervous system) age in addition to a general description of your mental state, which provides information that tells you both how good you might be at dealing with stress, and how old your nervous system is, independent of your actual biological age.

The wristband will have Bluetooth 4.0 connectivity, as well as an LED readout that can provide information independent from an attached smartphone. It advertises a full week’s worth of use on a full battery charge, and also has a built-in USB connector for charging. It uses a built-in heart rate variability sensor, combined with the company’s own algorithms to arrive at its various readings, which can be displayed either on the band itself or on a companion app.

Whether or not you believe in the science behind this, this is a clear growth market for quantified-self devices. There’s plenty of opportunity to explore the intersection of these devices and alternative theories of medicine and wellness, so it’ll be interesting to see if these kinds of gadgets can help bring health- and self-monitoring tech into the mainstream.



Scanadu Scout “Medical Tricorder” crowdsources testing for FDA

Real-life tricorder project, the Scanado Scout, has graduated to crowdfunding stage, with the DIY health monitoring tool looking to raise $100,000 and ship to backers by March 2014. The project, by startup Scanado, aims to turn a smartphone into a health tracking device – or “an Emergency Room in your pocket” – with a compact vital-sign reading puck that wirelessly communicates via low-power Bluetooth.

The Scout concept was first shown off late last year, the handiwork of a team at the NASA Ames labs. Held to the forehead, it beams information – including heart rate, skin/core body temperature, oxymetry, respiratory rate, blood pressure, ECG, and emotional stress – over to an app on your phone.

scanadu_scout_measuring

That data, Scanado suggests, could be interesting to a wide range of people. By preempting health issues, it could mean avoiding periods of sickness (and cutting down on medical insurance bills) by treating conditions early; meanwhile, athletes could use Scout to monitor the effectiveness of their fitness regime.

Meanwhile, life-loggers who might be drawn to wearables like Fitbit Flex or Jawbone UP are also a target group for the firm. They’re expected to find the wealth of data – and historical tracking – to be particularly interesting.

As for hardware, full details aren’t specified yet, but there’s Bluetooth 4.0 and apps for Android and iOS. It recharges via microUSB, and Scanadu claims that it’ll last for around a week, if used “a few times a day.”

Of course, any medical-grade device hoping to reach the market in the US needs to get FDA approval, and that’s the stage Scanadu is up to. The company has kicked off an Indigogo campaign to raise $100,000, but also needs early-adopters who will agree to share their data so that it can be used in clinical studies to demonstrate effectiveness.

If it raises its goal amount – and that looks likely, given at time of writing it’s already over $40,000 in – the first units are expected to ship out to backers in March next year. Those in early can get one for $149; when it launches, it’s expected to retail at $199.

Update: As expected, the Scout has already passed its funding goal, with 31 days left to run. More than 50-percent of the $149 units have been taken at time of writing.

Scanadu finalizes Scout tricorder design, wants user feedback to help it get FDA approval

Image

We first saw a prototype of Scout, the tricorder and companion app built by Scanadu for the Tricorder X-prize competition late last year. Today, the company is unveiling Scout’s final version and launching an Indiegogo campaign to let folks order Scout and sign up to participate in a usability study — which will provide Scanadu the user feedback needed to help its tricorder get certified by the FDA. In the six months since Scout was first revealed, the design has changed somewhat, and we checked in with company CEO Walter De Brouwer to get the lowdown on the new version.

Like the prototype, the new model tracks your temperature, respiratory rate, systolic blood pressure and stress level. Scout now pulls your vitals in ten seconds using just optical sensors, which enables it to read the vital signs of others — as opposed to the prototype which utilized an EEG sensor and could only record the info of the person holding it. Plus, thanks to some newly developed algorithms, it can now take both systolic and diastolic blood pressure readings with 95 percent accuracy. Running the algorithms to translate the optical sensor info takes a good bit of computing power, however. So, Scout got upgraded from an 8-bit processor to a 32-bit unit based on Micrium, the operation system being used by NASA’s Curiosity Rover for sample analysis on Mars. If you’re into supporting real world space technology being used to make science fiction a reality, the crowdfunding project of your dreams has arrived.

Axio returns as Melon, an EEG headband that’ll help you learn to focus

Insert Coin meet Melon, a headband that'll help you learn to focus

The quantified self movement’s gaining steam, with companies creating all sorts of gadgets to track our activity levels, sleeping habits and even what’s going on inside our heads. Melon’s an EEG headband that taps into your brain’s inner workings to show you how well you maintain mental focus. We actually saw Melon’s prototype predecessor last year when it was called Axio, and while this new band packs largely the same components, the design’s been refined to a much thinner profile. As before, its got a trio of electrodes for sensing brainwaves, a NeuroSky chip for filtering out extraneous electrical noise and Bluetooth 4.0 for offloading data wirelessly. It sends data to iPhones (Android’s in development) running the Melon app, which translates that info into a focus graph — generally speaking, the higher the neural activity in your pre-frontal cortex, the higher your level of focus. Users then input contextual data tags like time of day, type of activity and the surrounding environmental conditions to allow them to track variables that may affect their focus.

The Gadget Inside Me

I am not entirely human. All of the parts of a human being are inside me, but I have a few extra bits as well, not so much floating around as firmly secured in place. In some spots, these nonhuman bits hold me together. In other spots… well, that’s a different story.

I have a couple gadgets inside of me. One was forced on me; the other I chose. I made the choice in much the same way you’d choose a computer. I tried to future-proof myself. I chose an option that I could upgrade later. In the end, I made a decision that was not entirely rational, but rather based on passion and branding and aesthetics over performance. Like I said, just like a computer.

star_wars_lukes_hand

I’ll start with my leg, because it’s easier for me to talk about. I broke my ankle a few years ago. I was walking the dog on a very, very cold night in Newton, Mass, and the sidewalk all around the block was a track of ice fit for a speed skater. I took a bad step and slipped off the curb, and my tibia rotated wrong and crashed into my fibula, snapping it in multiple spots. I fell to the ground immediately, and that’s when I learned a couple things about myself.

First, I learned that I do indeed have a high tolerance for pain, something I’d always suspected but never bothered to prove. When the paramedics arrived to put me on a stretcher, they asked me to rate my pain on a scale of one to ten. I gave it a six. The worst pain I’ve ever felt, by the way, is a cracked tooth, which is about an 8, and it’s a great story, but for another time.

The second thing I learned about myself is that my body is capable of destroying itself with hardly any intervention from my mind. When they lifted me into the ambulance, with my foot askance and twisted, I asked if there was any possibility I could have dislocated it, instead of a break.

The paramedic told me: “well, anything you can locate you can dislocate.” But it was obviously broken.

“I bought a carbon fiber walking stick. It made the suffering more palatable”

I had titanium installed. The x-ray is awesome. I have an erector set in my leg, with screws holding me together. There’s no chance it can break again, I’m part fighter jet down there. I couldn’t walk for four months, and I was in pain and using a cane for another 2 months. I had an awesome rolling aid instead of crutches called a Roll-A-Bout. I highly recommend it if you break your ankle. I was faster on that rollabout than I ever was on both feet. When I needed a cane, I bought a high-tech, carbon fiber walking stick with spring loaded shocks and other features only useful for orienteering and nature photography. It made the suffering more palatable.

Now my only limitation is that I can’t stand on my tiptoe on that leg. When I tell people this they look at me like I’m telling them the old joke about the guy who breaks his hands and says to the doctor: “Doc, will I be able to play the piano when I’m healed?” The doctor says “Sure,” to which the patient replies “That’s great, because I could never play before.”

See, I’m a big guy. When people are meeting me for the first time, I’ll sometimes tell them to look for the biggest guy in the room, and that’s probably me. For the six months I was recovering from my broken ankle, nobody explicitly said it, but I know that my size must have been the reason such a shallow fall caused such a horrible injury. I’m not a 6’2″ basketball player jumping eight feet in the air to block a shot. I’m a six foot schlub who slipped off a sidewalk walking a 40 pound dog.

This brings me to the other gadget inside me. I have a device implanted in me called a lap-band. It’s like an inflatable donut . . . mmm, donuts . . . wrapped around my stomach. It makes my stomach smaller, and divides it into a small portion up top and the rest down below. This is supposed to be a weight loss surgery. You fill the donut with saline and it expands, contracting your stomach. Then, you eat less.

If you don’t eat less, you throw up. That’s actually a feature of the lap-band. It’s supposed to make you throw up. Also, because of where it’s located, higher up than your normal stomach, a full stomach actually feels more like choking on something at the bottom of your throat.

Is it any wonder this device doesn’t work? It sounds like high-tech torture. In fact, the lap-band has a shockingly low success rate. 70% of people who get a lap-band fail to lose weight. Your body adjusts to it. Your body naturally learns how to make you more comfortable, and you resume your old, horrible habits again. When I got the band installed, I lost a bunch of weight, then it came back.

I had other options for surgery, but they all involved heavy cutting and removing massive parts of me that would never grow back. The lap-band is reversible. In fact, I’m having it removed soon. I’ve already had it replaced once with a newer, better model. Now I’m having it taken out altogether. Time to try something different.

When you make the decision to have this band removed, the doctors will exclaim that the lap-band has failed. The euphemism of this choice is not lost on me. Let’s be honest, the band didn’t fail. My body didn’t fail. They did exactly what they were supposed to. They succeeded. I failed the band. The psychology of my thinking and habits overcame my physiology. I am weak. I take the blame. I have failed myself.

Perhaps this is why I’m sensitive to the power that psychology has over our choices, especially when it comes to technology. Technology buying should be a completely rational decision. I need this, therefore I buy it. I do not need to do that, so I will not buy something that does that.

“We look down on the passionate, the irrational”

We look down on people who make decisions they cannot rationally explain. We justify our purchases after the fact with rational arguments. I bought this phone because I have large hands. I needed a 60-inch television because I could not read the text on screen. I bought this watch because it is high quality and it will last longer.

We look down on the passionate, the irrational. We look down on people like me whose psychology has failed them. You bought a device you cannot understand, and you are a failure for not learning how to use it. You bought something because your friends all had one, and it made you feel good when you bought it, but you are missing out on all the capabilities of this other thing, the thing I carry with me every day.

I failed my band. The problems I have, which I pretend to understand, and for which I am regularly judged by people who also believe they understand, defeated me. I let them win. I am weak. I am passionate and I give in to irrational urges and desire. I have failed.

One day we’re going to see the utter stupidity in this form of judgment. One day we will understand the true power our subconscious minds hold over us. We will stop blaming people, and hating people, for making decisions based on emotion and passion. We won’t blame them when they fail the gadget, when we realize they may never have had the power to succeed.

iPad Smart Cover magnets could affect implanted defibrillators

It’s been discovered that the magnets in an iPad Smart Cover are strong to deactivate implanted heart defibrillators, according to a 14-year-old student who discovered the findings during her science fair project. Since then, the student has received a lot of attention from medical professionals and will even speak in front of 8,000 doctors in Denver for the Heart Rhythm Society.

ipad_2_smart_covers_5

Gianna Chien, who is a high school freshmen in Stockton, California discovered that if you lay the iPad face down on your chest while you’re laying down to take a quick snooze, the magnets in the Smart Cover can get close enough to the heart to cause implanted defibrillators to malfunction and shut off without warning.

However, defibrillators are designed to be turned off by magnets in the first place as a safety precaution, with the assumption that there’s no reason to have magnets close to your chest except to purposely turn off the defibrillator, but it’s easy when you’re laying down to simply rest an iPad on your chest while you take a nap.

Based on a past teardown of the iPad Smart Cover, there’s a total of 21 magnets, with four used to hold the Smart Cover to the iPad, eleven holding the Smart Cover in its triangular stand position, and a single magnet which flicks the iPad 2 in and out of standby mode. According to Chien’s experiment, around 30% of the 26 patients she tried it on had their defibrillators messed with. As for Apple addressing this issue, we could very well be hearing from them, but for the time being, let your grandparents know about this issue if they have a newer iPad with a Smart Cover.

Fitbit Flex less than three weeks away from UK

Fitbit‘s Flex activity tracker has gone up for presale in the UK, the wrist-worn exercise and sleep monitor expected to arrive on British arms at the tail-end of May. Launched in the US on Monday, the Flex – which we reviewed earlier this week – is one of the more affordable of the latest batch of trackers, undercutting Nike’s FuelBand and Jawbone’s UP.

Fitbit Flex

In fact, the Flex comes in at £79.99 (in the US, it’s $99.99) complete with two sizes of wristband and a wireless dongle for your computer. Alternatively it will sync via Bluetooth 4.0 with your iOS or Android device, though you’ll currently need either a Samsung Galaxy S III or a Galaxy Note II if you’re a Google OS user.

That’s down to different implementations of Bluetooth 4.0 on Android devices, which means most of the current line-up of phones simply won’t work with the Flex. Fitbit tells us that should change in the near future, however, and at least with the USB adapter you can get your exercise data off the band whenever you’re near a computer.

We also had some issues with sleep tracking mode, with side-by-side comparisons between the Flex and the UP suggesting the Fitbit version was seriously underestimating the length of time we were asleep. Still, it’s more comfortable than the Jawbone model. Presales kick off today at Fitbit’s site and Amazon, with retail store availability from May 27.

Keepin’ it real fake: China’s Codoon SmartBand pays homage to Jawbone Up

Keepin' it real fake Codoon SmartBand

Viewing it from afar, you could easily mistake this gadget for Jawbone’s Up fitness band. What we have here is actually the SmartBand from Chinese fitness accessories maker Codoon, and it’s almost a carbon copy of the Up in terms appearance and functionality. Bend this strip around your wrist to track your movement and sleeping patterns (with the ability to wake you up with vibration at the optimal sleeping cycle; just like the Up), and afterwards, plug the hidden 3.5mm headphone jack into either an iPhone or an Android device for analysis and sharing through Codoon’s website.

After we reached out to Baidu regarding the Baidu Cloud logo on the SmartBand, a spokesperson told us that it’s the first wearable developed on top of Baidu’s PCS (Personal Cloud Service) to sync and share data, and Codoon’s upcoming Bluetooth fitness products will work on the same platform (likewise for the Baidu Eye project). Still, it’s a real shame that the startup couldn’t come up with its very own design for its first hero product. Expect this rip-off to hit the market in early June for an unknown price — but you can already get an Up in China, anyway.
