We’re in the last few weeks for entries in the 2016 Hackaday Prize — specifically the challenge is to show off your take on assisstive technology. This is a hugely broad category and I’ve been thinking about it for a while. I’m sure there’s a ton of low-hanging fruit that’s not obvious to everyone. This would be a great time to hit up the comments below and leave your “hey, I always thought someone should make…” ideas. I’m looking forward to reading them and it might just inspire someone to spend the next couple weeks hammering out a prototype to enter.
For me, it’s medication. I knew this can be a challenging problem having gone through a few cycles of prescription medicines in my life. But recently I helped out a family member who was suddenly on many medications taken on eight different times a day — including once, twice, three, and six times per day. This was further compounded by sleep deprivation (having to set alarms at night to take the medicine) and drowsy/woozy effects from the medicine. I can tell you first hand that this is really tough for anyone to deal with and it’s incredibly easy to make a mistake or not be able to remember if you took a dose.
Pill Organizers Do No More or Less
We’ve seen a number of pill organizers before and that’s what I reached for in this case. However, that organizer only had four slots for each day. I didn’t hack it (other than writing on the doors with a Sharpie for when to take each) but even if there were added buttons or LEDs I’m not convinced this would be a marked improvement.
What you see above is my proposal for the medicine problem. Smartphones have become ubiquitous and the processing power and cameras of even budget phones are mind blowing. I think it is entirely possible to write an app that uses computer vision to recognize pills and sync them with the schedule. This may mean whipping the phone out of your pocket, or designing a pill box that has a phone stand next to it (saying that makes me think of using RPi and a Pi camera). Grab your pills and validate them under the camera.
Useful Augmented Reality
The screen of the phone would use augmented reality to overlay information about the pills it sees — you know, like Pokemon Go but in a way that enriches your life. ‘pills, catch ’em all!’ — new pills can be learned of the fly, delivering the user to a screen to identify the pill and the dosing schedule. Taking the validation picture will record when the medicine was taken, and the natural extension of this systems is a pharmacy’s ability to push your dose schedule to your account when you pick up the prescription. A stretch goal would be keeping an eye out for interactions.
This is all very much like how hospitals do it — they’re scanning bar codes on the packaging and the patient bracelet and recording it. This would be an easier user experience and quite frankly I think companies already in this space (like Snapchat and Niantic) could whip this up in a single-day hackathon no problem.
Is it the perfect system? Maybe not. But there is no perfect system or we’d be using it by now. We need you, the world’s talent pool, to step up and make life a little better. Do it in prototype form by October 3rd and you’ll be eligible for one of twenty $1000 cash prizes and a chance at winning the Hackaday Prize. But even if you don’t build a single thing, one idea could be the spark that lets others change the world for the better. So let’s hear it!
For most of us, our touch-screen smartphones have become an indispensable accessory. Without thinking we tap and swipe our way through our digital existence, the promise of ubiquitous truly portable computing has finally been delivered.
Smartphones present a problem though to some people with physical impairments. A touchscreen requires manual dexterity on a scale we able-bodied people take for granted, but remains a useless glass slab to someone unable to use their arms.
LipSync is a project that aims to address the problem of smartphone usage for one such group, quadriplegic people. It’s a mouth-operated joystick for the phone’s on-screen cursor, with sip-and-puff vacuum control for simulating actions such as screen taps and the back button.
To the smartphone itself, the device appears as a standard Bluetooth pointing device, while at its business end the joystick and pressure sensor both interface to a Bluetooth module through an Arduino Micro. The EAGLE board and schematic files are available on the project’s hackaday.io page linked above, and there is a GitHub repository for the code.
Technology is such a part of our lives these days, and it’s great to see projects like this bridge the usability gaps for everyone. Needless to say, it’s a perfect candidate for the Assistive Technology round of the Hackaday Prize.
Hard as it is to imagine, lie detectors have been sold as children’s toys for a number of years. A simple battery-operated device clipped to your fingers and would show the conductivity of your skin. The concept — which is probably not very reliable — observers that lying causes you to imperceptibly sweat which causes a sudden increase in your skin’s conductivity. These cheap toys would have a meter and you’d note the meter deflection to determine if the subject was lying.
You can debate the amusement value of interrogating your friends, perhaps, but they were pretty common and still exist (including some that shock you if they detect you are lying). Seventeen-year-old [BuildIt] has his own modern take on this classic device using — what else? — an Arduino. You can see a video of the device below.

Rearchers of the Harvard Medical School built a 2 feet by 4 feet (61 x 122 cm) large petri-dish to visualize the evolution of bacteria. Their experiment induces mutations in E. coli bacteria by exposing them to gradually increasing concentrations of antibiotics.

Exoskeletons are demonstrably awesome, allowing humans to accomplish feats of strength beyond their normal capacity. The future is bright for the technology — not just for industrial and military applications, but especially in therapy and rehabilitation. Normally, one thinks of adults who have lost function in their limbs, but in the case of this exoskeleton, developed by The Spanish National Research Council (CSIC), children with spinal muscular atrophy are given a chance to lead an active life.
Designing prosthetics for children can be difficult since they are constantly growing, and CSIC’s is designed to be telescopic to accommodate patients between the ages 3-14. Five motors in each leg adapt to the individual symptoms of the patient through sensors which detect the child’s intent to move and simulates what would be their natural walking gait.

DIY medical science is fun stuff. One can ferret out many of the electrical signals that make the body run with surprisingly accessible components and simple builds. While the medical community predictably dwells on the healthcare uses of such information, the hacker is free to do whatever he or she wants.
A good first start is to look at the relatively strong electrical signals coming off of the heart and other muscles. [Bernd Porr] has put together a simple bioamplifier circuit, and his students have made a series of videos explaining its use that’s well worth your time if you are interested in these things.

You don’t have to know a word Swedish to understand that 86-year old [Lasse Thörn] is the coolaste modernaste pensionären in Gränna. All you have to do is see him rolling on his walker-assisted hoverboard and you’ve got the whole story.
Still, not knowing any Swedish and the spotty nature of Google translations makes it hard to discern the details of this build. Did [Lasse] build the folding aluminum bracket that connects the battery-powered hoverboard to his walker himself? We guess that he did, since another story says that he built a pedal boat back in the 1950s because he thought it sounded cool. He also says that he gets a lot of attention when he’s out on his contraption, and that other seniors have asked him to build one. [Lasse] says he’s too old to start a business; we don’t think he’s giving himself enough credit, but if he’s willing to leave the field of affordable personal mobility open to the rest of us, we say go for it.
We’ve seen lots of hoverboard builds lately, and lots of hate in the comments about the use of that term. Seems like the false advertising vibe grates on folks, but face it: “rolling wheelie board” is kind of awkward, and until technology catches up with the laws of physics, it’s the best we’re going to do.
