First Digital Computer Music Recording from 1951

Wed, 18 Jun 2008 23:05:50 -0500

Historians have found the earliest digital computer music recording, which was made in 1951 by the BBC for a musical performance in a children's radio show.

The recording captures one of the earliest computers to use short term random access memory playing God Save the King, Baa Baa Black Sheep and a short piece of Glenn Miller's In The Mood.

The Ferranti Mark 1 computer was built by UK electrical engineering firm Ferranti in collaboration with Manchester University, UK. It was the world's first commercial computer, and nine were sold between 1951 and 1957.

Robot guitar tunes itself

Wed, 14 Nov 2007 19:21:24 -0600

Tuning an instrument can sometimes be a pain, but Gibson Guitar has come up with the world's first robot guitar, Les Paul Robot Guitar, that keeps itself in tune.

"It will not make you a better guitar player but it will allow the average player to access some very sophisticated tunings," Gibson Guitar Chief Executive Henry Juszkiewicz told Reuters on Tuesday.

The six nonstandard preset tunings were used on hits ranging from "Honky Tonk Women" by The Rolling Stones and Hendrix's "Voodoo Child" to Led Zeppelin's "Going to California" and Joni Mitchell's "The Circle Game."

Gibson says the robot guitar is aimed at amateurs who have a hard time keeping their guitars in tune, as well as professionals who now use technicians during concerts to keep about 100 guitars tuned to different keys.

Only 4,000 limited edition guitars will be available worldwide on December 7. Price ta? $2,500.

Who Killed the Electric Car

Mon, 16 Oct 2006 15:31:48 -0500

In the late 90s electric cars were popping up all over California. These were not hybrid vehicles—they ran without gasoline and had zero emissions at the tailpipe. These were not powered by hydrogen fuel cells—they ran on currently available battery technology and were charged on the grid.

They were reliable.
They were fast.
They were functional for about 90% of the US market.

They were discontinued.

Manufacturing was stopped. All of the existing electric automobiles were taken off the road, crushed and disposed of. Who is responsible for the death of the electric car and why did this happen?

The documentary "Who Killed the Electric Car" was released earlier this year to select theaters in the US. If you weren't able to catch it when it was in your area, it looks like the screening version has just been ~~posted to~~ removed from Google Video. Now we can all ~~watch it~~ imagine it playing on our computers, presumably without driving to the theater in our gas-guzzlers.

Update: Shortly after posting this, the video was taken offline. I've replaced the video with a PBS interview with the film's director, Chris Paine.

Update 2: Who killed the electric car videos? The PBS interview is now gone as well. Oh well, no electric car for you. No movies about them either.

SWAN helps the sight-impaired

Wed, 11 Oct 2006 16:06:41 -0500

The Georgia Institute of Technology is in the process of developing a System for Wearable Audio Navigation (SWAN) which will help the sight-impaired navigate through daily life.

SWAN is a wearable computer:

Besides a pendant-sized wireless GPS tracker, there are light sensors and thermometers that help distinguish between indoors and outdoors. Cameras gauge how far away objects and obstacles are. A compass establishes direction. And an inertia detector tracks the roll, pitch and yaw of the user's head.

All the data are crunched by a computer in a backpack, which relays high-pitch sonar-like signals that direct users to their destinations. It also works with a database of maps and floor plans to help pinpoint each sidewalk, door, hall and stairwell.

Like a sonar device, the SWAN system sends out audible blips that quicken as users move closer to a preprogrammed target and slow as they get farther away. The sound of a hinge opening plays as it passes by a door, and cues can signal bathrooms, restaurants, stores, and other attractions.

The sounds are sent through bone-conducting headphones, specialized devices that are worn behind the ears to appease users reluctant to have their ears covered.

"This is not intended to replace a guide dog or a white cane," Walker said. "This just supplements it."

The SWAN reminded me of the research project one of our favorite Lego League Teams has been together for their presentation a couple years ago.

MIT's Assist Sketch Understanding System and Operation

Thu, 05 Oct 2006 13:07:01 -0500

This man shows us how the MIT Assist Sketch Understanding System and Operation works by sketching a simple mechanical device onto the drawing board and then demonstrating how the system understands the sketch through movement.

I could see this tool being used not just in the classrooms but also in the workplace.

Cool Toys From SIGGRAPH

Wed, 16 Aug 2006 09:19:22 -0500

My friend Nate wrote me the other day about the SIGGRAPH 06 conference:

A friend of mine from CMU's Human-Computer Interaction program went to SIGGRAPH last week.

If you aren't aware, SIGGRAPH is supposedly THE conference for people who design human-computer interfaces. She took some videos of really cool toys, I thought I'd share a few of them with you.

All of the videos are now located at:
http://www.aubreyshick.com/SIGGRAPH06/

Definately check out the command interface, it's amazing.

I'm not positive, but it looks like the command interface might be the latest incarnation of the Multi-Touch system that I've been drooling over for a while. The OS in this new video has a minority report look to it and allows users to drag, rotate, and scale windows with natural hand movements.

The MIT huggable also caught my eye. The huggable is cute bear equipped with various skin sensors, cameras, microphones and an embedded wireless PC which allows it to interact with its owner on a pseudo-emotional level. It's an interactive stuffed animal, and it's way less creepy than robogrover.

The page has links to 7 AVIs in total. If you have any trouble playing them, try to right-click and download them first rather than attempting to play in-browser.

Urban Challenge Moves to the City: DARPA Announces Third Grand Challenge

Tue, 02 May 2006 15:12:27 -0500

The Defense Advanced Research Projects Agency (DARPA) officially announced its third Grand Challenge to be held on November 3, 2007.

The DARPA Urban Challenge will feature autonomous ground vehicles executing simulated military supply missions safely and effectively in a mock urban area. Safe operation in traffic is essential to U.S. military plans to use autonomous ground vehicles to conduct important missions.

DARPA will award prizes for the top three autonomous ground vehicles that compete in a final event where they must safely complete a 60-mile urban area course in fewer than six hours. First prize is $2 million, second prize is $500,000 and third prize is $250,000. To succeed, vehicles must autonomously obey traffic laws while merging into moving traffic, navigating traffic circles, negotiating busy intersections and avoiding obstacles.

Details of the Challenge can be found at the DARPA Grand Challenge web site.

Nascar Laptop: What's under the hood

Thu, 30 Mar 2006 19:58:36 -0600

I was picking up some printer ink today at CompUSA and saw the oddest thing... Nascar laptops.

These laptops have got to be fast. I've got to get my hands on one of these... yuk yuk. Be sure to check out the demo... priceless.

"Gentlemen, start your engines."

Want more Nascar in your life? Nascar now sells meats, vegetables, and chainsaws. [BoingBoing]

Firefly Glow: Now Available in Orange and Red

Mon, 20 Mar 2006 11:28:57 -0600

Efficiency of Light Technology
Incandescent Bulbs: 10%
Flourescent Lights: 20%
Light Emitting Diodes (LEDs): 30%
Firefly Butts: 90% efficient

Scientists have succeeded in unraveling the mystery — at the protein structure level — of the mechanism at work in the glowing tail of the “Genji firefly” (Luciola cruciata Motschulsky), which is considered to have the highest luminous efficiency of any known source of light. The results of the joint research carried by the Institute of Physical and Chemical Research (RIKEN) and Kyoto University are to be published in the March 16 edition of the British science journal Nature.

The researchers were able to adjust the chemical composition of the firefly's bioluminescent enzyme, luciferase, to create orange and red glowing bug juice. According to the article over at Pink Tentacle, work is currently being done to complete the three primary colors by recreating the blue glow from the sea firefly.

Multi-Touch: High Tech Touchscreen

Wed, 01 Mar 2006 18:39:37 -0600

Check out this video of a cool multi-input touchscreen. The user is able to interact with 3d applications by using both hands and multiple fingers to manipulate objects on the screen.

My favorite part, though, is what appears to be a two player, multi-handed version of our favorite game, Planarity.

Pretty slick, I must say.

Origami - Microsoft's New Ultra-Portable Computer?

Wed, 01 Mar 2006 17:11:45 -0600

There's been a lot of buzz over the last few days about a new ultra-portable, tablet pc product that Microsoft will be launching soon. It looks like MS even kicked off a bit of a viral campaign, posting an extended spot on YouTube and a cryptic flash site.

I'm told that this is something entirely seperate from the Windows Mobile group, so my guess is that it'll run the latest incarnation of their full-fledged tablet OS instead of something more akin to the embedded OS on the Pocket PCs.

We should know more details "very soon" (likely tomorrow), but from the looks of things, it's a half-notebook sized PC tailored for portability and device connectivity. The video emphasizes the device's handwriting recognition capabilities, which I'm hopeful for.

I got a chance to play around with an XP Tablet PC a couple years ago, and I ended up becoming really frustrated with its voice recognition system. Hopefully we'll see some improvements here as well.

What has me excited about this, I guess, is that it appears that MS is making a stab toward a combined hardware/software platform, similar to what they've done with the XBox, or Apple has done with all their music products. Perhaps with control over both the hardware and software, they'll be able to really fine tune some of the more advanced interface features. Fingers crossed for the best.
