Wearable laugh sensor knows when you're feeling good

laugh_sensor At the 2015 Wearable Device Technology Expo in Tokyo in January, a tech firm introduced a small lapel worn sensor that can tell when the wearer's laughing, talking, or in trouble. Based on 10-years of "laugh-detecting" research, it's meant to help monitor the health of senior citizens. According to researchers:
To know they are "laughing" will help you see that they are happy and mentally well. "Falling" may indicate an emergency situation. This device reassures you that your loved ones, who live far away, are doing well.

Nova Scotia artist generates furious noise from hand-made sound machines

wefwefwefwefwfwefw32

Artist Rebecca Baxter of Halifax, Nova Scotia makes noisy, grating, often ethereal sounds from machines she designs and solders herself. Demand has been high for her one-offs, including those used in recordings and performances by Flaming Lips, Electric Wurms, New Fumes, Mike O'Neill, Panos, METEOROID, Holy Fuck, Buck 65, and Oscillator Sunshine Machine.

Now she's launched a campaign to raise money to build more sophisticated handmade instruments. So far her devices have been stand-alone, creating sound from oscillators inside, but her next model, the Omega, is slated to have inputs for a guitar or keyboard. More videos: 1, 2, 3.

Learn the sign language for "screengrab" and "SMH"

sign

Online mag Hopes & Fears asked an educator in American Sign Language and his young assistant to demonstrate various internet jargon such as "emoji" and "photobomb". Each demo is captured in a short video loop. SMH portrays all the disgust involved in shaking one's head at something really stupid; Screengrab involves a nice gesture that enacts the mechanism of a phone display flashing in one's hand.

Since there's no central authority for such neologisms, some signs were ones used among friends while others were reached by consensus among members of the Deaf community online.

The dystopian future of quantified babies

baby2

A group of design students from a Swedish university published an insightful academic paper last year spoofing all the baby health trackers now pitched to parents. The trackers measure things like a baby's breathing rate, heart rate, and sleep, and are made by startups including Mimo Baby, Owlet, Sproutling, and Monbaby.

Is this fear mongering for new moms? Or will these devices actually offer valuable data on infants? I think it's too early to tell. But the paper does a good job of critiquing the design pitfalls of the user experience. It argues such devices could needlessly raise anxiety and remove intuition from parenting.

There's a cool hand-drawn storyboard of a new mom deciding not to go the park with Johnny after she binges on biometric data:

The beauty of an energy-free treadmill

treadmill copy

I've been coveting the world’s best manual treadmill, the EcoMill ($7,000). But until I have a spare seven grand, I have to run with conventional electric mills. Most use a lot of juice -- between 800 and 1800 watts continuously -- because they have ot lock down a consistent pace with a low-cost mechanism.

At a sleepy little gym and pool complex here in Vermont, on a conventional electric machine this week, the current was so high it overloaded a nearby stereo receiver playing upbeat pop music for a water aerobics class. All of a sudden, seven wet, angry seniors swarmed from the pool. Encircled by bright floaties, they demanded I quit running so the music would come back on. I tried to explain the concept of a blown fuse and how treadmills use high wattage because they can’t rely on the friction like spin bikes and how the world really should invent a cheap electricity free mill. But at that only enraged them, and they gripped the handrails and rocked the machine side to side.

I really want my own EcoMill for the house. Or maybe a human-sized hamster wheel.

Watch how responsive laser car headlights can change night driving

Of all the CES videos this year, the most surprisingly interesting one demonstrated responsive laser auto headlights. In the concept demo, sensors gauge driving conditions and objects as they come into view, even splitting the beam so it doesn't blast oncoming vehicles with light.

Harmful aging considered


Charlie Stross lays out the state of aging: "cognitive functioning burdened by decades of memories to integrate, canalized by prior experiences, dominated by the complexity of long-term planning at the expense of real-time responsiveness...truck by intricate, esoteric cross-references to that which has gone before."

Gecko Feet Inspire Wall-Climbing Gloves

I love it when nature inspires technology. A group of researchers has developed a glove that will allow humans to stick to and scale walls. This bit of amazingness is being modeled on the feet of geckos.

4481220352_7e88697cb1_b

Unlike tree frogs, whose sticky toe pads give these amphibians the ability to cling to surfaces, gecko toes instead use friction created by microscopic hair-like structures called setae that hold up the animal's body weight.

This adaptation has been studied before, but so far physics and gravity have prevented any practical application for human use. We're simply too large and heavy. That has all changed now based on the work of Michael Elliot Hawks of Stanford University, who has developed a synthetic nano-fiber "setae" that can hold the weight of a human.

If and when these become available to the public, I'm definitely adding them to my wish list!

Tech projects vein maps during blood donations

The Australian Red Cross Blood Service is testing a technology to project a vein map on the arms of blood donors during the phlebotomy.

"Vein visualisation technology uses near infrared technology to project an image of the vein onto the skin," says Dr. Dan Waller, a senior researcher with the organization. "Veins have a lot of deoxygenated haemoglobin that absorbs near infrared light and the device is able to use this information to project the image. The machines have settings to manage individual differences.
