Simulations: Ten Cool Things People are Doing

9 03 2012

Last week on http://www.presterafx.com/wordpress, Gus Prestera blogged about simulations and posted a very useful list that summarizes well argument points we want to bring to your next PTA or whoever you are trying to get onboard. Here is the list:

#1: Sims get legit
#2: Sims go to class
#3: Sims creep into page turners
#4: Sims get visibility
#5: Sims go cloning
#6: Sims invade virtual worlds
#7: Sims go back to basics
Read the details of #1 to 7 at Part 1
#8: Sims go 3D
#9: Sims get game!
#10: Sims go mobile
Read the details of #8 to 10 at Part 2

Song of the Machine

17 10 2011

I.am.blown.away. This is absolutely amazing work. It all started with a notification from a TED conversation that I had to jump in this morning:

“As unmanned drones, algorithms and prosthetics blur the distinction between man and machine, what, if anything, does it mean to be human?” hosted by Anab Jain (designer and founder of the London and India based collaborative design studio Superflux.

The site is shock-full of amazing projects and proof of concepts. I was particularly interested in the research done on retinal protheses (injecting a virus to infect the degenerate eye with a light-sensitive protein + an optoelectronic augmented wearable).

Song of the Machine explores the possibilities of this new, modified – even enhanced – vision, where wearers adjust for a reduced resolution by tuning into streams of information and electromagnetic vistas, all inaccessible to the ‘normally’ sighted. ” (read more here: http://superflux.in/work/song-machine)

I understand that this particular project targets the sight-challenged people. The implications are heartbreaking-ly awesome. Imagine a blind person seeing the world for the first time, or recovering his/her sight after an accident or disease. But let’s imagine the use of the augmented goggles and joint portable device that project a visual interface for use in mainstream, regular, day-to-day augmented reality. Many conversations have brought up the use of 3D panoramic headsets/glasses to be rewired to project ones Layar-enhanced smartphone view, or a pair of glasses already uploaded with such AR layer (maybe similar to the smart windshield, ref. https://sabinereljic.wordpress.com/2011/05/31/autoglass-hints-at-ar-windshield/). But I have yet to see any prototype of such glasses. On the other end, Superflux offers this proof of concept and is tabling the work on the device and interface with Dr. Degenaar leading the team.

Did you watch that Song of the Machine video? What do you think? find similar work? Post it here and give us your feedback!





Online gamers crack AIDS enzyme puzzle

20 09 2011

Repost from AFP 09/19/2011 (see source at the end of article). Online gamers have achieved a feat beyond the realm of Second Life or Dungeons and Dragons: they have deciphered the structure of an enzyme of an AIDS-like virus that had thwarted scientists for a decade.

The exploit is published on Sunday in the journal Nature Structural & Molecular Biology, where — exceptionally in scientific publishing — both gamers and researchers are honoured as co-authors.

Their target was a monomeric protease enzyme, a cutting agent in the complex molecular tailoring of retroviruses, a family that includes HIV.

Figuring out the structure of proteins is vital for understanding the causes of many diseases and developing drugs to block them.

But a microscope gives only a flat image of what to the outsider looks like a plate of one-dimensional scrunched-up spaghetti. Pharmacologists, though, need a 3-D picture that “unfolds” the molecule and rotates it in order to reveal potential targets for drugs.

This is where Foldit comes in.

Developed in 2008 by the University of Washington, it is a fun-for-purpose video game in which gamers, divided into competing groups, compete to unfold chains of amino acids — the building blocks of proteins — using a set of online tools.

To the astonishment of the scientists, the gamers produced an accurate model of the enzyme in just three weeks.

Cracking the enzyme “provides new insights for the design of antiretroviral drugs,” says the study, referring to the lifeline medication against the human immunodeficiency virus (HIV).

It is believed to be the first time that gamers have resolved a long-standing scientific problem.

“We wanted to see if human intuition could succeed where automated methods had failed,” Firas Khatib of the university’s biochemistry lab said in a press release. “The ingenuity of game players is a formidable force that, if properly directed, can be used to solve a wide range of scientific problems.”

One of Foldit’s creators, Seth Cooper, explained why gamers had succeeded where computers had failed.

“People have spatial reasoning skills, something computers are not yet good at,” he said.

“Games provide a framework for bringing together the strengths of computers and humans. The results in this week’s paper show that gaming, science and computation can be combined to make advances that were not possible before.”

Technology that can help physically-challenged humans communicate

31 05 2011

Reposting David Teeghman’s post on DiscoverNews, July 15th 2010

“Slowly but surely technology is seeping into airplanes, which up until a couple of years ago felt like a final reprieve from the digital world. You can use your cell phone at certain times before take off and after landing, you can watch DVDs on your laptop and you can surf the Internet using in-flight Wi-Fi.

But it doesn’t stop there.

How about playing a thought-controlled game?

“We think it’s time that in-flight entertainment does more than simply distract you,” said Ariel Garten, CEO of Toronto-based Interaxon, which created the technology.

Passengers wear a special headset sensitive enough to pick up brainwave activity, basically electrical patterns resonating outside your head. Proprietary software converts the brainwave activity into binary code, that is the ones and zeros that make up computer code. That code becomes a signal that controls the game. With practice, a person can learn to manipulate his own brainwave activity.

The system scans your brain to see if you are in the mood for relaxation or concentration. If you are giving off alpha brainwaves and want to relax, the system sees that and sets up something soothing like a meditation program.

If you are giving off beta brainwaves and are looking to do something that requires more concentration, you could try out a program that improves your golf swing.

The ability to operate your electronic gizmos just through your brain is becoming more and more popular. You can even control robots just with your mind now, so it’s not a huge leap forward to be able to play games on an airplane using your mind as the remote control.

This technology was first put on display June 5 and 6, 2010, at On the Wings of Innovation, a global aerospace convention in Ontario. Everyone from astronauts to Apple founder, Steve Wozniak, gave the technology a test drive:”

My comment: How wonderful to adapt this for basic functions such as writing, playing music or painting. However, in an era when we have to pass laws for people to stop multitasking while driving, I don’t think that using this technology for driving a car is a good idea.
