Quick Post/Videos: Evolving Soft Robots (Cornell's Creative Machines Lab); Leap Motion + Google Earth Experiment (PO-MO)

Evolution in Action: Soft Robots!

A team from Cornell's Creative Machines Lab have been researching simulations of evolutionary robots, and as a result, have come up with an entertaining video of what they've discovered so far.  According to the project's website, the work was inspired by developmental biology, to use evolutionary algorithms as a tool to develop locomotion.

The following description of the video was quoted from Jeff Clune's YouTube site:

"Here we evolve the bodies of soft robots made of multiple materials (muscle, bone, & support tissue) to move quickly. Evolution produces a diverse array of fun, wacky, interesting, but ultimately functional soft robots. "

LEAP Motion + Google Earth
Meg, from PO-MO, has a LEAP Motion developer kit. Earlier this week, LEAP Motion provided support for Google Earth integration, and asked developers to submit videos of their experiments.  I like the Superwoman theme of this video!

Little Digits Counting and Early Math App, by Cowly Owl - Chris O'Shea

Fun with Early Math:  App by Chris O'Shea - Cowly Owl


Chris O'Shea is an artist and designer who uses technology in creative, playful ways. Over the past year or so, he's devoted some of his attention to designing engaging iPad apps and digital toys.  Below is a video of his Little Digits app in action:


Little Digits from Cowly Owl on Vimeo.

Here is the information from the Vimeo site:

"Little Digits is a fun educational app that teaches children about numbers by putting a new spin on finger counting. Using the iPad multi-touch screen, Little Digits displays number characters by detecting how many fingers you put down.  Children can learn to associate the number on the screen with the number of fingers they place down, whilst enjoying the unique characters and animations of the Little Digits world...They are also games that introduce small addition and subtraction calculations, where you can work out the answer using the same multi-touch finger detection."

Interesting Videos I Almost Missed (Future/Emerging/Creative Tech)

Creative Tech Videos I Almost Missed


I admit that sometimes I just don't have the time to hang out and watch interesting or quirky tech/future tech videos on the web.  Here are a few that passed me by the first time around.  

Enjoy!


The first video for this post is of an interactive game installed permanently for children at the Royal London Hospital.  Woodland Wiggle is a work commissioned by Vital Arts, in collaboration with Nexus Interactive Arts, Chris O'Shea, Felix Massie, and Brains & Hunch.  The game was created in C++ using openFrameworks, and relies on an Xbox Kinect camera.   The installation is part of play and garden spaces designed as healing environments for young patients.  (See links in the "Related" section for more information.)




The next video is the creation of Igor Labutov, Jason Yosinski, and Hod Lipson, of the Cornell Creative Machines Lab.

AI vs. AI:  Two chatbots talking to each other


I liked this video because I once created a chatbox video game for an AI for Games class I took several years ago, and have fond memories of the hours I spent reading the textbook supporting the display on the right- Artificial Intelligence: A Modern Approach)

Tom Jenkins and Simon Sharp, of thetheory, created the following two video shorts. Address Is Approximate is a stop-motion video about a lonely desk toy who makes a journey across the US via Google Maps Street View.   Speed of Light uses a pocket projector, a video feed, and creativity to create an augmented reality-like police-chase short.  According to information from the Vimeo website, Speed of Light was filmed using a Cannon 5d Mkll + HD MiniCam, with MicroVision projectors.

The Uncanny Valley is Here! Activision's real-time character demo is chillingly real. (Not an April 1st joke.)

Up with Activision in the Uncanny Valley

I first heard the term 'uncanny valley' about eight or nine years ago when I was taking a 3D-modeling class.  At that time, the technology available was not close to reaching this valley - where robots or computer-generated characters are so real that they are almost repulsive.

A lot has changed over the years.

The following video, recently featured by Activision Blizzard during the 2013 Game Developer Conference, has attracted much attention in just a few days, partly because it is so real.



Although I noticed that a little more work needs to be done with the teeth, I was impressed. I liked the quality of the eye shaders that were used in the creation of this demo.  Examples of faces created with this feature turned on and off can be found on Jorge Jimenez' blog.  Jorge's slides from a 2012 course offered during SIGGRAPH provide additional information.

Computer processers have become powerful enough to handle quite a lot of processing, and the tech world has been spreading the word. Below is a presentation by Jen-Hsun Huang, CEO of Nvidia, about the company's work simulate the human face, touching on the 'uncanny valley':


Although the use of this technology to create characters, realistic on many levels, seems to be a bit creepy, it might be OK after some refinement.  There are a few questions that remain unanswered.   What would be the impact on children or teens who might spend many hours each week playing games with such realistic characters?  I'd hate to have a nightmare featuring one of these guys!

I think that this technology might have some potential for use in serious games and simulations, such as preparing emergency workers to handle a variety of realistic scenarios. Games with realistic digital characters, capable of generating a range of facial expressions, might be useful to support the learning of social interaction skills among young people with autism spectrum disorders.

What happens when a 2-year old wakes up to the sound of the Google Map Lady? "I CAN'T turn left right now!"

Google Map Lady says, "Turn Left", toddler yells from the back seat, "I CAN'T..."

If you are new to this blog, you might not know that I'm the grandmother of a 2-year-old little boy.  Watching him grow in an increasingly technology-enriched world has been an eye-opener at times, from his first interaction with my iPad, fingers-and-toes at 7 months of age, to his attempts at rafting down a digital river, playing the Kinect Adventure! River Rush game. 

Technology is rapidly changing how we learn, interact, and navigate our world.  Designers, developers, and others who are involved in the process of creating for the near future must be mindful of the ways newer technologies might play out in the real world, where the "user" is not always the person intended for the "user experience".  Off-the-desktop technologies are rapidly advancing, and impact people of all ages, wherever they happen to be.

Today's story is just one example.

I'm fortunate to live about a 35 minute drive from my grandson, and for this reason, I sometimes take him out and about, especially when his parents have a lot of errands to run.

After a nice lunch at Amelie's French Bakery  near the NoDa neighborhood (Charlotte, NC),  and exploring the floor murals in the little mall behind the bakery, I told my grandson that we were going to the "Big Park" (Freedom Park). 

He was so excited, but within a few minutes, he was fast asleep.

I drove up towards the airport to kill time, thinking that he'd wake up and we'd watch the planes. He was still sleeping.  Now what?

I opened up Google Maps on my cell phone to get directions from the airport to the Carolina Raptor Center at Latta Plantation Park, since I wasn't sure how to get there from the airport.

About 15 minutes later, as the Google Map Lady gave directions, Levi woke up, saying "What's that sound? A lady's voice?". The Google Map Lady spoke again, and said something like, "In 1000 feet, take a left turn." 

Levi replied empathically, "I CAN'T turn left right now!". Google Map Lady responded with the next direction, and Levi replied, "I CAN'T do that!". 

The little guy was visibly upset, because he thought the lady was telling him what to do. It was obvious to him that he could not comply with her request.

What to do?   How do I explain the "Google Map Lady" this to a 2-year old? 

This is how I handled the situation:

I told him that the lady's voice was to help me know where turn so I could drive to the raptor center.  I kindly told him that the directions were just for me, not little boys who can't turn the car because they are in car seats and can't drive. He nodded and said, with relief, "Lady's voice for Mi-Mi, NOT for little boys", and was fine after that.

Note:
Although I did not know it at the time, my grandson had somehow wriggled out of the left harness of his car seat. I discovered the problem as I went to unfasten him from the car seat, and wondered how long he'd not been secured safely.  It hadn't occurred to me that this would happen - everything was in place at the beginning of our ride, as you can see from the first picture.  

As I lifted my grandson out of the car seat, it crossed my mind that it would be a good idea if car seats came with sensors to let the driver know if the car seat straps, snaps, or buckles became unsecured. (Systems like Forget Me Not provide a warning system to parents if the child is forgotten in the car.)

After conducting a quick search, I found that Sherine Elizabeth Thomas has applied for a patent that includes the use of a sensor to alert the adult that a child has unbuckled their seat belt.  I think that a system could be developed to provide an alert if the child was not safely secured, as in the case of my wiggly grandson.
