Digital vs. Analog

Digital vs. Analog
Modern electronic devices - computers, video game consoles, cell phones, iPods, etc. - all store data in digital format.
Digital data gets its name from the fact that almost any type of data in an electronic device - characters, images, video and sound - can be broken down into smaller parts and given numeric (or "digital") values.
For example,

The Second Generation: 1956 to 1963...

Processing
Transistors were invented in 1947 as an alternative to vacuum tubes for use as electronic switches.  At first they were more expensive (transistor = $8 vs. vacuum tube = 75¢).  However, by the mid 1950s they had decreased significantly in price and size, and began to see widespread use in radios, televisions - and computers.
The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors.  Although the transistor still generated a great deal of heat and still required massive amounts of wiring, it was a vast improvement over the vacuum tube.

 One of the most successful second generation computers was the IBM 1401, which was introduced in 1959.  By 1964, IBM had installed more than one hundred thousand units (which could be rented for $2,500 / month), capturing about one third of the world market.

Researchers at the University of Southern California’s ICT Graphics Lab have created a new type of holographic display that can generate simultaneous 3D views for multiple observers without the need for special glasses.

Battery History

Batteries have been around longer than you may think. In 1938, archaeologist Wilhelm Konig discovered some peculiar clay pots while digging at Khujut Rabu, just outside of present-day Baghdad, Iraq. The jars, which measure approximately 5 inches (12.7 centimeters) long, contained an iron rod encased in copper and dated from about 200 B.C.

 Email in your eye? Next-generation video screen glasses could lay messages or GPS over your field of vision..

Translucent TV: Lumus' PD-18-2 is a set of spectacles that can beam high-quality images directly into your eyes but allows the user to see through the images too

As advances in computer technology make gadgets ever smaller and more portable the idea of carrying a screen of any kind could soon be outdated. 
Consumer products with screens have dropped in size from computer to laptop to tablet via phone.

Will touch drive Microsoft Surface sales or will Surface drive touch..


The demo applications Microsoft has shown so far for its Surface touch-tabletop system --for  ordering drinks, sharing photos by dragging them and finger painting -- have left me cold. 
But at the Consumer Electronics Show this week, Microsoft is discussing and demonstrating some different Surface application prototypes that seem somewhat more compelling. 


                   
During his CES keynote, Microsoft Chairman Bill Gates showed off a snowboard-customization demo that indicates the kinds of interactive retail applications which might shine on Surface multi-touch systems. Microsoft issued some talking points about the demo, claiming it "provides a clear solution to common consumer pain points," including (according to Microsoft):
  • being overwhelmed by choices
  • not having enough information
  • can’t make it yours
  • want to share it with friends
"The (Surface snowboard) application showcases the four key attributes of a surface computer including; multi-touch, object recognition, direct interaction and multi-user," said an e-mail message sent to me by the Surface team.
Microsoft also is highlighting at this week's CES show a "wine-bar demo application." This app looks similar to the drink and food ordering application Microsoft has been showing off for the past few months during public Surface demos. But there's one new element I hadn't seen before that is more educational. Tags on customers' wine glasses, when placed on the Surface tabletop, call up a map of the region from which the wine originates. The touch-activated map can provide all kinds of additional details about the vinters, the grapes, the climate, etc. For those who listened closely to Gates' Sunday night keynote, there was a hint that gaming and office-productivity applications are in the pipeline for a Surface "desk," "meeting room table" or other kinds of future Surface systems, as well. From the transcript of Gates' remarks:
Gates and others at Microsoft are still betting big on natural user interfaces -- touch, speech, gestures -- as being the keys to the input kingdom. Supposedly, these input modes were going to take off during the "first digital decade." But Tablet PCs didn't take hold at anywhere near the rates he predicted.
While touch and speech will no doubt take off on cell phones and on-board auto systems, I admit I'm still am a doubter about how quickly or well they'll be adopted by PC users. Call me a Luddite, but if the Surface had a keyboard, I'd definitely prefer it over touch or speech.
What's your take on the Surface? Will touch technology drive the Surface? Or will Surface finally get more Microsoft users to make use of non-keyboard-based input technologies?
