Convergent Innovation

Last night, I read a great article in the May 12 issue of the New Yorker. It's called "In the Air," by Malcolm Gladwell. It focuses on Nathan Myhrvold, once the CTO of Microsoft, but now the co-founder of Intellectual Ventures, a firm that invents ideas.

But what caught my eye was the mention of a scientific phenomenon of simultaneous discovery called "multiples." Apparently some of the greatest inventions of humankind were discovered almost at the same time by different people in different parts of the world who had little or no association with each other.

Here are some examples:

• Isaac Newton and Gottfried Leibniz discovered calculus
• Charles Darwin and Alfred Russel Wallace discovery evolution
• Joseph Priestly and Carl Wilhelm discovered oxygen (thank goodness)
• Charles Cros and Louis Ducos du Hauron invented color photography
• John Napier, Henry Briggs and Joost Burgi invented logarithms
• Galileo, Scheiner, Fabricius, and Harriott discovered sunspots
• Alexander Graham Bell (photo) and Elisha Gray invented the telephone

An article published by William Ogburn and Dorothy Thomas in 1922 describes 148 such multiples. And David Lamb wrote about it in his book, "Multiple Discovery: The Pattern of Scientific Progress." (If there wasn't just one copy available on Amazon for $122, I might buy it.)

I was astounded to learn of this phenomenon. How amazing....how cosmic that strangers can be separated physically by miles, even countries, and yet demonstrate almost identical inventions. Almost in the next moment, though, I was reminded of something in biology called convergent evolution, which is the process whereby organisms not related to each other, separated by continents, even, independently evolve similar traits. For example:

• Hedgehogs and porcupines have spines
• Bats and birds have wings
• Anteaters and armadillos have long, sticky, insect-lapping tongues
• Koala bears and humans have fingerprints
• Monkeys and chameleons have prehensile tails

The phenomenon is also evident in plants, fish, and even cellular functions. A reason for convergent evolution is that an ecological niche (living in the trees or in the water) force an organism to adapt. So, similar niche, similar adaption.

It seems to me that this is what's happening with innovation. A technological niche opens up and inventors adapt to fill it. Progress is inevitable and will no doubt occur in different parts of the world at the same time. It makes the idea of patenting seem silly, in a way. Greedy. It's a bit like the bird claiming he had wings first. Or the monkey filing a patent on his tail. Could it be that open source pans out to be a natural law in the invention universe? Are clinging to ideas and new inventions simply out of our hands?

Treadmill Goes Both Ways

When you think "treadmill," you think gym—not virtual reality. But take a look at this. It's CyberCarpet, a treadmill that moves front-to-back and side-to-side. As a moving floor in a VR room, it could make a person feel like she's walking in the woods or along a city street.

The contraption is made up of several treads that move side-to-side, while collectively, all of those treads rotate front-to-back.

The device uses cameras to track the position and posture of the walker and uses this information to control the velocity of the treadmill and, ultimately, interactions with the virtual environment. A biff harness helps prevent nasty tread rash.

Check it out.

Eyes Free Access to Your Mobile Phone

First there were headsets that offered a hands-free mode on mobile phones. Now there's an audio program that allows a person to access calendar or contact information without looking at the screen or the buttons. Hence, eyes free.

The prototype version, called Blindsight, comes from the folks at Microsoft Research. You can see a video here. It works on flat mobile phones (not the clamshells). The speaker holds the phone backward and upside down, using the keypad button to access information. An audio voice provides the necessary information without disrupting the conversation. That's because the listener on the other end can only hear the person speaking and not the audio calendar or contact information.

It's an interesting concept, but how would something like this work with clamshell phones, which are so popular in the States? Also, if you're using a headset, you wouldn't need the function at all.

SmartCane Helps Prevent Senseless Falls

More than 4 million people in the U.S. use canes. And although the staff is meant to help, sometimes it does more harm than good. People use canes improperly, experience repetitive stress injuries, or rely on the device in the presence of obstacles, which can lead to a bad fall.

Now researchers have developed an electronic cane that is embedded with sensors, a computer, and wireless networking technology. The SmartCane can, among other things, detect usage patterns, predicts outcomes, such as a fall, and inform the patient or caregiver about how the device is being used in the first place--which can improve safety and performance.

The technology comes out of the University of California, Los Angeles and was recently presented at the BodyNets 2008 conference.

Rug Lights Up Your Life

I love simple tech solutions like this electro-luminescent rug that lights up only when you step on it. How cool is that? It uses a rechargeable battery for power and operates by pressure--when you put weight on it, it emits a glow. The perfect night-light for someone like me, who prefers sleeping in an ultra dark room, but is prone to bumping a knee in the absence of a night lite.

The rug is one of 31 innovations competing in this year's Ideal Home Show (in London) for Home Invention of the Year. Finalist are listed in two categories: Concept Products and Iconic Products.

Remote Control Finally Makes TV Mindless

I have yet to understand why there are so many buttons on television remote controls. Just when I figure out how to interpret my device, I go to my friend's house, and it's like stepping onto another planet. His has twice as many buttons and the two most used (volume control and channel changer) are among the smallest.

Shouldn't television watching be mindless?

A team of researchers from Philips Research in Eindhoven, The Netherlands, think so. They've invented a remote control that makes the experience far less complicated.

Called "Remote Touch," the device incorporates a laser pointer, a specially designed transparent sheet that fits over the display, and control options at the edge of the screen that are sensed by  position-sensitive photodetectors.

Instead of scrolling through menu options, the user points the laser at the screen. (You can read the press release here.) The transparent sheet has microscopic structures that direct the laser to the photodedectors and allow the watcher to basically point at what they want to control.   

If that's not simple enough, you can always get the remote control that's operated by remote.

Blood Powers Electronic Tattoo

I know some folks feel lost and confused without their mobile phone, but this might be going too far. Someone has invented an implantable touch screen that works as a cell phone display. And what's more, the electronic tattoo gets its power from blood.

The 2x4-inch interface is made from flexible silicon and silicone. It's rolled into a tube and then inserted into the skin through a small incision. Once there, it unrolls to lie flat just below the skin. Two tubes on the device are connected to an artery and a vein, allowing blood to circulate to a fuel cell. As glucose and
oxygen pass through the fuel cell, they produce electricity.

Because blood is passing through, the device could work as a biological sensor to monitor a person's health. Ok, but that still gives me the willies.

Gravity Lamp Lasts 200 Years

It doesn't need to be plugged in. Instead, this lamp is powered by gravity. It's a design concept that won second prize at the Greener Gadgets Design Competition held early this month in New York. The lamp, called Gravia, is an acrylic column about four feet high that has a long, tall screw running up the middle. A weighted brass weight spirals down the screw in a slow-motion drop, and in the process, turns a rotor that powers a generator that creates electricity. The power illuminates LEDs, which glow bluish at about 600 to 800 lumens, or about the amount of a 40 watt bulb.

Gravia's inventor, Clay Moulton—a student at Virginia Tech—estimates that the if the lamp were used eight hours a day, 365 days a year, it would last 200 years.

A patent is pending. For more info, contact Virginia Tech Intellectual Properties, or see here, which provides information about the lamp and the designer’s philosophy.

Cube Radio Not for Squares

Normally I don't blog about gadgets, but this little do-hickey takes full advantage of technology for a simple,knock-yourself-in-the-forehead-cuz-why-didn't-someone-think-of-this-before elegance.

The Iona Cube internet radio from Cambridge Consultants has no buttons, dials, or levers. The user changes stations by turning the cube to one of four sides. According to the research, Internet radio listeners favor about four stations. (Is this true, MM?) And I wonder if the cube couldn't be designed into a hexagonal prism.

The fifth side of the cube is for the speaker; the sixth for on or off. To make the music louder or softer, just rotate the cube right or left. It's like you're pretending to turn up the volume, but then you really are!

Thanks to the Engineer Online for their article.
