Snap specs, hearing aid app, Touchpad Paint, Apple Watch heart

Snap’s fledgling Spectacles sold just over 63,000 units in March quarter — In a sign of how tough the market for Apple’s rumoured augmented reality glasses could be [ie, if Apple was to make some] Snap is estimated to have sold just over 63,800 pairs of Spectacles in the March quarter.
Snap didn’t provide exact numbers in its results, but did admit to making just $8.3 million in its “other revenue” category, according to TechCrunch. Dividing by the Spectacles’ $130 pricetag gives a figure of 63,846.
About $4.5 million in Spectacles were sold during the December quarter, or roughly 34,615 units. Until the February launch of online sales, the Spectacles were essentially an experiment for Snap, sold only through hard-to-find vending machines and a special New York City pop-up store. Even these limited sales only began in November.
The Spectacles are designed to shoot 10- to 30-second clips of first-person video, mainly for sharing in Snapchat, though they can be viewed elsewhere. Footage is shot in a unique circular format, and to dispel privacy concerns, lit rings appear whenever the glasses are recording. [So they’re just video cameras you wear on your face.]

Hearing Aid Pro provides hearing assistance with an iPhone — One of the ‘badges of honour’ that comes along with advancing years is hearing loss. Whether it’s medically-caused, the result of too many years of listening to loud music, or just plain old age, almost everyone gets to the point that their hearing isn’t as sharp as it used to be. Hearing Air Pro (NZ$14.99/US$9.99) is designed to act as a hearing aid that runs on your iPhone, and since Steven Sande was recently diagnosed with significant hearing loss in my left ear, he thought I’d give it a try.
Now, why would someone want to use a $15 app to help out hearing? Easy: hearing aids are ridiculously expensive (a good number are well over NZ$3000) and many people feel a certain stigma wearing them, while few have issues with people wearing the iconic Apple earbuds. [Even if you’re just using this for walks in the park while enjoying hearing more, it’s pretty good value for that price.]

Carnegie Mellon research team created Touchpad Paint — What if you could spray-paint a piece of plastic or wood, and use it as a Magic Trackpad? Engineers at Carnegie Mellon University have created touchpad paint, which can turn any object or surface into a touch sensitive one. Project Electrick is based on an algorithm that can read a finger-press by sensing changes in electric flow on a conductive surface, called electric field tomography.

Study uses Apple Watch heart rate sensor to detect serious heart condition with 97% accuracy — New research conducted by the University of California, San Francisco, in collaboration with Apple Watch app Cardiogram, shows Apple Watch’s heart rate sensor can aid in the detection of atrial fibrillation, a common heart arrhythmia that can lead to stroke.
