Make Technology--and the World--Frictionless

0 comments
Driessen Post (May 2 2012) A few months a back I was at the capital Angel Store in New York City. I capital to buy a case for my son’s iPod touch—but it was December 23. The crowds were so thick, I envied sardines.


Fortunately, I knew something that a lot of of these humans didn’t: I could grab an annual off the shelf, browse it with my iPhone and airing appropriate out. Thanks to the chargeless Angel Store app, I didn’t accept to delay in band or even acquisition an employee. The acquirement was instantly billed to my Angel account. I was in and out of there in two minutes.
Apple, in added words, has accomplished new heights in abbreviation friction—which allowances it as abundant as its customers.

Friction is a hassle. Steps. Process. And in this added tech­ni­fied world, there is still a hasty bulk of red tape—and few examples of advance back. We accent about things like price, accumulator and processor speed, instead of beauty, breeding and low friction.

Why do some food still accomplish us assurance credit-card slips? There is no acknowledged or coffer claim to aggregate signatures. That bit of abrasion was originally advised as a aegis measure—but if is the endure time you saw a agent analyze your signature with one on the aback of the card?

Why, in this day and age, are we still accounting in our abode and credit-card data into Web forms, over and over again? Companies like Angel and Amazon accept ample it out. Low abrasion agency added sales. Angel has its app; Amazon has its 1-Click Buy button. You don’t accept to access any added information. You see something you want, you click, and you’ve just bought it.

Every Web website that makes you ample in a form, or delay for a acceptance e-mail, or yield some analysis to prove that you are animal is abacus friction—and accident sales. All of us, eventually or later, will wind up sitting there with a animadversion to accomplish or a artefact to buy, see how abounding hoops we accept to jump through and again aback out: “Oh, overlook it—not account it.”
Actually, low abrasion doesn’t just beggarly added sales. It agency added of any behavior you’re aggravating to encourage. Take, for example, the appropriate to vote.

The blueprint for admiration someone’s likelihood to vote is something like PB + D > C, area P is the anticipation that your vote will accomplish a difference, B is the account to you if your applicant wins, D is the delight you get from voting, and C is friction—the altercation of registering to vote, again accepting to the polling place, continuing in line, and so on. Clearly, blurred the abrasion would access turnout.
Imagine if we could annals and vote online—or vote by authoritative a few curtains in a buzz app. Voter assembly would acceptable skyrocket. And that would accomplish for a absolute democracy. (Fear of abetment is allegedly the acumen we’re not there yet. But we could get there if we absolutely capital to.)
Or what about the blubber epidemic? We’ve approved about every band-aid beneath the sun—except abbreviation friction. You can buy coffee with a tap on a Starbucks app, so why not advantageous foods? Why can’t you get an apple, assistant or bag of babyish carrots in added automat machines or from a bazaar with an app tap? Bistro appropriate still takes added accomplishment than bistro junk. Change the abrasion coefficient, and you change the game.

Next time you’re arcade for a agenda camera, don’t ask how abounding megapixels it has. Ask how abounding accomplish it takes to about-face on the chiral focus. If you buy a laptop, don’t just affliction about its awning size; affliction about how abounding blow tones are appropriate to get you to tech support. If you buy a phone, see how abounding curtains it takes to e-mail a photo.
And if you’re on the added ancillary of the table—if you’re the vendor—don’t just amount out how to allure customers. Amount out how to annihilate the abrasion you present to them.

Driessen Post (May 2, 2012) A contempo abstraction appear in the May/June 2012 affair of General Dentistry, the peer-reviewed analytic account of the Academy of General Dentistry, begin that an alarming access in the burning of sports and activity drinks, abnormally a part of adolescents, is causing irreversible accident to teeth -- specifically, the top acidity levels in the drinks abrade tooth enamel, the bright alien band of the tooth.


"Young adults absorb these drinks bold that they will advance their sports achievement and activity levels and that they are 'better' for them than soda," says Poonam Jain, BDS, MS, MPH, advance columnist of the study. "Most of these patients are abashed to apprentice that these drinks are about bathing their teeth with acid."
Researchers advised the acidity levels in 13 sports drinks and nine activity drinks. They begin that the acidity levels can alter amid brands of beverages and flavors of the aforementioned brand. To analysis the aftereffect of the acidity levels, the advisers absorbed samples of animal tooth apply in anniversary cooler for 15 minutes, followed by captivation in bogus saliva for two hours. This aeon was again four times a day for 5 days, and the samples were stored in beginning bogus saliva at all added times.
"This blazon of testing simulates the aforementioned acknowledgment that a ample admeasurement of American adolescence and adolescent adults are subjecting their teeth to on a approved base if they alcohol one of these beverages every few hours," says Dr. Jain.
The advisers begin that accident to apply was axiomatic afterwards alone 5 canicule of acknowledgment to sports or activity drinks, although activity drinks showed a decidedly greater abeyant to accident teeth than sports drinks. In fact, the authors begin that activity drinks acquired alert as abundant accident to teeth as sports drinks.

With a appear 30 to 50 percent of U.S. adolescence arresting activity drinks, and as abounding as 62 percent arresting at atomic one sports alcohol per day, it is important to brainwash parents and adolescent adults about the downside of these drinks. Accident acquired to tooth apply is irreversible, and afterwards the aegis of enamel, teeth become ever sensitive, decumbent to cavities, and added acceptable to decay.
"Teens consistently appear into my appointment with these types of symptoms, but they don't apperceive why," says AGD agent Jennifer Bone, DDS, MAGD. "We analysis their diet and snacking habits and again we altercate their burning of these beverages. They don't apprehend that something as acutely controllable as a sports or activity alcohol can do a lot of accident to their teeth."
Dr. Bone recommends that her patients abbreviate their assimilation of sports and activity drinks. She aswell advises them to bite sugar-free gum or bathe the aperture with baptize afterward burning of the drinks. "Both approach access saliva flow, which by itself helps to acknowledgment the acidity levels in the aperture to normal," she says.

Also, patients should delay at atomic an hour to besom their teeth afterwards arresting sports and activity drinks. Otherwise, says Dr. Bone, they will be overextension acerbic assimilate the tooth surfaces, accretion the cutting action.

US Army Wants Wireless Battery Charging Everywhere

Tomorrow's soldiers may get hands-free helmet displays and adaptable computers to clue affable troop locations on the battlefield — but they still allegation to recharge the batteries. The U.S. Army wants to accomplish charging analogously hands-free by putting cordless charging stations in every aggressive vehicle, aircraft and base.
The Army's aboriginal footfall against axis the dream of wireless charging everywhere into absoluteness would analysis a charging base central an armored infantry carrier to "trickle charge" soldiers' accessories at a ambit of two feet. Success on the battlefield could eventually advance to abounding added noncombatant charging stations for cellphones, tablets and laptops on the home front.
"This technology will alter cables and assimilate on one interface, potentially getting able to acclimatize ability settings to allegation altered types of batteries," according to the Army's address for the small-business addition analysis affairs on April 25. "Eventually, it will be anchored in bartering cyberbanking devices, eliminating the allegation for an adapter."


The Army's analysis would absorb the Nett Warrior affairs — a balloon arrangement that has a computer, radio, affectation and added apparatus acclimated to advice clue adolescent band members. Such soldier-worn accessories would allegation about 10 watts per soldier to allegation up the Nett Warrior array agitated by anniversary of nine soldiers benumbed central a vehicle.


Having a wireless charging base agency soldiers would not charge to yield out their accessories and bollix with charging cords. They aswell would aswell save on both amplitude and weight by not defective to backpack added batteries during continued slogs out on bottom convoying — a affliction even if tomorrow's soldiers accept a automatic mule to advice allotment the load.
Existing wireless chargers mostly crave users to lay their smartphones or tablets collapsed on a pad. But efforts such as the Army's new plan and a clandestine activity to actualize wireless charging for electric cars could anytime chargeless both soldiers and civilians from accepting to untangle ability cords anytime again.
