Information Visualization: Revisiting Hans Rosling's TED presentation

This semester I'm taking "Visualization and Visual Communication", which is a course I've wanted to take for a while now. Today, we looked at a variety of websites that provide interactive information data visualization applications, which I'll share on this blog in the near future.

After class, I came home and revisited Hans Rosling's TED presentation about information visualization, and thought I'd share it on this blog. This video is about 20 minutes, and provides a good overview how simple interactive information visualization applications can help to convey concepts and correct misconceptions in an engaging, effective manner.



For those of you who work in K-12 settings, imagine how powerful this method of visual communication would be for students, if presented on an interactive whiteboard or display.

Johnny Lee's Wii Hacks: Can the Wii be configured to provide immersive learning experiences?

Thousands of people have been following Johnny Lee's progress as he hacks Nintendo's Wii system. Johnny Lee is a graduate student in the Human-Computer Interaction Institute at Carnegie-Mellon, and he has come up with the most amazing, creative uses for the various components of the Wi.

Take a look at Johnny's recent video of his work creating desk-top VR using a large-screen display:

"Head Tracking for Desktop Virtual Reality"


Although the Wii is a game system, the possibilities for the Wii as a platform for immersive educational experiences in the classroom - as well as in the family room - are endless, provided that a few people in educational technology are willing to contribute to this effort at the same level demonstrated by Johnny!

Since more classrooms are getting large-screen displays in the form of interactive whiteboards, there might just be a chance for teachers to use a few more tools to invigorate and engage their "digital native" students!

I think that learning activities utilizing the power of the Wii and Johnny's present (and future) hacks might also be very effective in reaching the needs of students who have disabilities. Visual and kinesthetic learners would also benefit, as well as kids and teens who are considered to have hyperactivity.

Johnny provides the code and instruction for all of his hacks on his website at http://johnnylee.net

Johnny Lee's work is creative interactive multimedia technology at its best!

Scratch: A new programming language for kids that supports stories, animations, games, music, art, and web-sharing, from MIT.

"Scratch is designed to help young people (ages 8 and up) develop 21st century learning skills. As they create Scratch projects, young people learn important mathematical and computational ideas, while also gaining a deeper understanding of the process of design." (Scratch website)

Scratch can be downloaded, free of charge, from the website. It can run on Windows as well on Macs. There are over 12,000 contributors to this project, with over 60,000 registered members. The website provides plenty of support for teachers and students.

The Scratch project is run by the Lifelong Kindergarten group at the MIT Media Lab, along with the UCLA School of Education and Information Studies. The project was funded by the National Science Foundation.

I'm looking forward to playing with Scratch on a touch-screen or interactive whiteboard.

Keepon, BeatBot's robot: Potential to promote social behavior in children with autism spectrum and developmental disorders.

The BeatBots project develops rhythmically intelligent robots for research and entertainment. In the video below, the responsive robot, Keepon, dances to the Spoon song, "Don't You Evah".

Keepon was developed by Hideki Kozima and programmed by Marek Michalowski, from Carnegie Melon.

According to an article by David Templeton in the Pittsburgh Post-Gazette:

"While the videos have proven Keepon's human appeal, the double-bubble yellow fellow's key role is to interact with children. Keepon has shown promise in encouraging social behavior in children with developmental disorders, including autism."

"Keepon's simple appearance makes children comfortable, and its lifelike movement makes it attractive to them," Mr. Michalowski said. "This combination creates an environment in which social interaction is encouraged.""

"While the robot can dance to almost any song, it also can identify visual and other sensory rhythms, helping to prove how rhythm and synchronization in body language are paramount in human interaction. As such, Keepon has schooled roboticists in how to improve human interaction with robots."

An example of Keepon's attentive and emotive actions:
