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.

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."


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:
