Interactive information visualization: Digg labs website

I thought I'd share a view examples of information visualization as it relates to on-line news. Stories are grouped in various configurations over time. Click on the images below to see each example in real-time:

NEWSMAP
Click on the image to link to Newsmap.

" Newsmap is an application that visually reflects the constantly changing landscape of the Google News news aggregator. A treemap visualization algorithm helps display the enormous amount of information gathered by the aggregator. Treemaps are traditionally space-constrained visualizations of information. Newsmap's objective takes that goal a step further and provides a tool to divide information into quickly recognizable bands which, when presented together, reveal underlying patterns in news reporting across cultures and within news segments in constant change around the globe."


DIGG

STACK
"Diggers fall from above and stack up on active stories." If you click on a story, you'll get a pop-up that provides more details about the story, including information over time.


SWARM
Digger swarm around different categories of stories and make them grow. You can look at popular stories, newly submitted stories, or all activity. Click on a circle, and you'll get more information, and the option to keep or "kill" the story.

BIGSPY
"Bigspy: Active stories appear at the top when people digg them. Bigger stories have more diggs..." If you click on a story, you'll link to more information about it from the digg website.


ARC
"Stories arrange themselves as users digg them. Larger stories have more diggs." If you click on a story, you'll link to more information about it from the digg wesbsite.



Check back for more examples- and leave a comment if you have others to share.

About: Programming for interactive multimedia applications- WPF, Silverlight, EduSim, NeuroVR..

Part I Musings: Learning about application development and programming at mid-life:

I thought I'd write on a more personal level this time.

I'm a school psychologist, so in 2003, my motivation for taking computers at mid-life stemmed from my desire to create engaging interactive multimedia games for learning, games that could be played on hand-held devices as well as on the interactive whiteboards that I noticed were inching into my schools.


It was difficult for me to figure out how to get from Point A to Point B.

I shouldn't have been shocked to learn that most introductory programming classes provide instruction, as well as endless lab assignments, that are geared for people who want to make business forms and manipulate business-related data, build e-commerce websites, or create relational databases for... banks!

I now can make a mortgage calculator forms that adjust for various scenarios and provide cute error messages, in beginning Visual Basic.Net, C#, and Java. I can create a database that will let users look up part numbers for all sorts of widgets, in all sorts of combinations, and ensure that client data can be easily accessed in a nice looking form.

Why should I learn all of the old stuff when there are so many new avenues to explore?

Over the past few years, I've been fortunate to take a variety of classes that were not readily available just 8-10 years ago:

Computer/Internet Multimedia. Computer Music Technology. Game Design/Development. AI for Games. Ubiquitous Computing. Web Development Tools. Virtual Reality for Education and Training. These courses have motivated me to learn more about programming. The traditional programming courses had the opposite effect.


PART II
Keeping up

I recently attended a day-long code camp at Central Piedmont Community College to learn more about Windows Presentation Foundation (WPF) and Silverlight. WPF and Silverlight provide the foundation for applications that can run on Microsoft's Surface. WPF and Silverlight provide designers and developers with more efficient ways of developing visualization and interactive multimedia applications.

The architecture behind WPF and Silverlight seems to align more with the way people think and envision, which in my opinion, gives hope for those of us who have toyed with the idea of programming, but were frightened off the first time they opened up a traditional programming textbook.


Part III Visualization and Interactive Multimedia

For more information about WPF, Silverlight, design, etc, read Sam Batterman's (a Microsoft Evangalist) recent blog post: Some thoughts about WPF and Data Visualization

Here are some pictures and text that I lifted from Sam's blog that will give you a picture of what I'm talking about:


"Here's an application that one of our partners built in a few weeks - all WPF and actually, not complicated code...getting that heart rendered was probably less than 100 lines of code. This app is used in a hospital for documenting heart surgery procedures. You can draw and annotate the 3D surface, rotate the heart, etc."


Angiographer


Can you imagine how kids would love to manipulate something like this in a science class?! This would be great on an interactive whiteboard or display.

This focuses on user experience, much more so than applications in the past. For more information about designing for user experience, take a look at the link to Bill Buxton's book, "Sketching User Experiences."

Bill Buxton's webiste, "Multi-touch systems that I have known and loved" is a good resource for those of you who'd like to get a better picture of multi-touch systems and interaction.

(I'll write more about WPF and Silverlight after I get my laptop repaired and have a chance to experiment some more.)

Croquet and EduSim


Right now, I've been experimenting with
Croquet, which uses Squeak, and EduSim, which is powered by Croquet, to put together some learning activities for students.The best part is that Croquet is open-source, and all of the EduSim applications are free.

Here are some pictures that link to short video clips from the Greenbush EduSim website:







Neuro VR


Another application that I'm working with is NeuroVR.

NeuroVR is a free virtual environment that was designed for use in clinical settings. If you don't have access to virtual-reality hardware, you can still use NeuroVR on a desktop or large-screen display. Available 3D environments include an office, a supermarket, a park, a classroom, a poolside setting, and a home.

Andrea Gaggioli, Ph.D., is the Chief Technical Officer of the this project. He's also behind the Positive Technology blog, which is a great resource. Andrea is a
researcher working at the intersections of psychology, neuroscience, and emerging technologies.

NeuroVR allows the clinician (or educator) to easily insert pictures, objects, and videoclips into each virtual world. Doors open and close, and you can move items around in the environment. For example, fruit set on a table can be moved over to a counter.

In my opinion, NeuroVR has potential not only in the area of rehabilitation and therapy, but in special education as well, particularly for students who have multiple special needs, including severe autism. A variety of "how-to" videos are posted on DaevornLi's YouTube channel.


Here are some videos clips to give you a better picture of the application:

Question about games and learning....

Someone recently asked me this question:

"If you look at Sim type games, for example Roller Coaster Tycoon, these are without question games that are filled with lessons and real-world applicable knowledge. Do you think kids go into a game like this knowing they're learning useful skills?"


Read my response on the TechPsych blog.


Any comments?

Cross Posted on TechPsych: Classroom 2.0 - Social Networking and Resources for Educators

Classroom 2.0 is a good resource for educators who would like to keep up with the fast pace of technology. If you work with digital natives, you know how difficult it can be to keep one step ahead of the game! Classroom 2.0 provides forums, Wikkis, and resources on a variety of topics and the content is maintained by members of the network, which at the last count was at 3998.

From the Classroom 2.0 website

"The social network for educators using collaborative technologies!"

"Welcome to Classroom20.com, the social networking site for those interested in Web 2.0 and collaborative technologies in education. We especially hope that those who are "beginners" will find this a supportive community and a comfortable place to start being part of the digital dialog. Feel free to explore!"

Cross Post: Children of the Code

I came across the Children of the Code website today and thought I'd share it- if you are familiar with Children of the Code project, please leave a comment, since I haven't yet explored the entire site.

Childrenof thecode.org is an on-line multi-media resource that is part of a public/social education project to that aims to spread information and education about "The Code and the Challenge of Learning to Read it"

The project has four main components:
  1. A three hour Public Television, DVD and Web documentary series;
  2. A ten-hour college, university, and professional development DVD series;
  3. A series of teacher and parent presentations and seminars;
  4. A cross-indexed website/database containing audio, video and transcripts with the world's leading experts in fields related to reading.
The website includes over 100 interviews of people from a wide range of disciplines who are committed to promotion of health, education, and well-being of children, youth, and in turn, communities and society.

Here is the project's abstract:

"Abstract: Our children's cognitive and emotional development, self-esteem, academic, and later social and economic success, all depend on how well they learn - on the health of their learning. Whether we are involved in parenting, teaching, cognitive science, psychology, pedagogy, curriculum design, instructional design, direct instruction, constructivism, assessment, multiple intelligences, learning styles, learning differences, learning disabilities, learning theory, learning communities, organizational learning, preschool, elementary school, middle school, high school, home school, unschooling, college, university... we all share the responsibility of stewarding the health of our children's learning."


I'd recommend starting with the on-line video tour of the project:
http://www.childrenofthecode.org/Tour/index.htm

The following is a quote from an interview with David Boulton, the director of the Children of the Code project:

"The mission of the Children of the Code project is to catalyze and resource a transformation in how our society thinks about the "code" of our written language and the "challenges involved in learning to read it.". I think we're living in the "Stone Age of Literacy." Our lack of understanding of what is involved and what is at stake in acquiring literacy is wreaking havoc on the lives of our population, including children"

"..the first think I hope i that it (the project) changes the mental lens through which parents and teachers see struggling learners. I want them to see someone who is struggling as somebody who is struggling with an artificially confusing technology (written language) and somebody who is in significant emotional and cognitive danger.

"What I hope is that people realize that if children and adults struggle too long with the process of acquiring literacy, it can seriously affect how they develop and grow and learn. Struggling to read causes many, many people to grow up feeling ashamed of their mind.."

Links to the list of some of the interviews of "name" researchers and educators are posted on the TechPsych blog, or you can visit the site's interview list.
