"Natural User Interface or ~ NUI Group is an interactive media group researching and creating open source machine sensing techniques to benefit artistic and educational applications."



Virtual Math Museum: Online Math Art:

The Virtual Math Museum has a wealth of visual information useful to those in and outside the field of math. The mathmatical art section has links to the works of Paul Nylander, George Hart, Titia van Beugen, Brian Johnston, Bathsheba Grossman, Jos Leys, Paul Bourke, Jean Consant, and Luc Benard.

Each of the Math Artist pages provides information about the artist that in my opinion, would be useful to teachers who aim to encourage students to consider pursuing STEM-related careers. (Science, Technology, Engineering, Math).

The content of the entire Virtual Math Museum website is impressive on a large display or interactive whiteboard!


FYI:
The group in charge of the 3D-XplorMath software development project and the related Virtual Mathematics Museum website project is the 3DXM Consortium, an international volunteer group of mathematicians.

Paul Bourke's Experiments in Interactive Visual Immersion in Second Life - and more....

I thought I'd devote a post to Paul Bourke's exciting work in the area of what I call "interactive visual immersion".

According to a bio on a math art website, Paul's working life "has revolved around high performance computing and computer graphics, in particular scientific visualisation: the use of computer graphics to represent scientific data with the aim of enhancing understanding of the underlying structure and processes." Paul is also interested in the use of "novel display technologies that can further enhance the understanding of large and complicated geometric datasets...These engage capabilities of our visual system not exploited by traditional computer displays..."

Paul recently participated in the the Computer Games, Multimedia & and Allied Technology 08: International Conference & Industry Symposium on Computer Games; Animation, Multimedia, IPTV & Edutainment. (CGAT'08, Singapore, April 28-30)

The above picture is from his paper, Evaluating Second Life as a Tool for Collaborative Scientific Visualization. (pdf), taken from Paul's webpage, where you can find a link to the slides from his talk.

Bourke points out that there are few software tools available that support shared, remote collaborative scientific visualization. What is available is expensive, exploratory, and/or difficult to install and operate. Bourke proposes that Second Life might prove to be a useful tool for collaborative SciViz, despite some current limitations. Second Life is a cross-platform 3D environment that was designed specifically for interaction between many people, and it allows for texture mapping, which is a plus for visualization work. Burke notes that there are limitations, such as Second Life's low geometric complexity.

Paul Bourke's website includes a page that lists all of his papers, articles, and seminars, with impressive visuals alongside each entry. Since I recently completed a visualization class and also gave a short presentation about accessible games for health, I found many of Bourke's papers intriguing:

Vertical dome (iDome): Visualisation and Navigable movies
Visualization for scientists, museums, public outreach, and education
Immersive environments and applications to gaming
Exploiting our sense of touch for scientific visualization.
Tactile Visualization: Feel your data!
Apple technology powering displays that engage the human visual system
iDome and digital projection into hemispherical domes

Take the time to explore Bourke's entire website. Look at his texture library and his "other" section!

Seth Sandler's "How to Make a Cheap Multitouch Pad" YouTube video is going viral...

Seth Sandler, a member of the NUI group, has worked very hard at putting together low-cost multi-touch screen surfaces. Seth has a background in music, so his projects focus on interactive music applications. Over 315,000 people watched this video within the week that it was uploaded.

Thanks Seth, for sharing this vision with the world!

Hint for high school teachers: This sort of thing would be a great project for an after-school technology club!

Cross post via Tech Psych: Games for Health conference

I recently presented at the Games for Health conference in Baltimore, Maryland. The attendees and presenters at the conference came from a variety of fields- game development, education, occupational and physical therapy, health, bio-mechanical engineering, media arts, and more, all interested in sharing ideas about using game, simulations, and virtual worlds to improve health.

Many of the topics covered during the recent Games for Health conference apply to K-12 settings. If you think about it, many children and teens are at risk for health problems that will adversely impact their lives as adults. If we can provide a means for young people to develop healthy behaviors and attitudes at an early age, we will help to ensure healthy futures, for individuals and communities alike.

If you have a little time, you can listen to the overview provided in an audiocast consisting of interviews with Ben Sawyer and others involved with the conference.

My presentation slides
- Game Accessibility and Health Education in K-12 Settings - from the pre-conference, are posted SlideShare, where you can find slides from other presentations on the Games for Health group section.

You can find more information on the Pioneer Portfolio of the Robert Wood Johnson Foundation website, including a section about Games for Health.
