Augmented Reality Project Sounds like a perfect learning activity for Second Life

I’ve been cleaning off my desk in preparation for the move later this month and I came across an article on the Augmented Reality Project that MIT and Harvard are developing. It sounds like a perfect fit for educational activities in Second Life.

“With funding from a U.S. Department of Education Star Schools Program grant, researchers at the Harvard Graduate School of Education, the University of Wisconsin at Madison, and the Teacher Education Program at MIT have developed an "augmented reality" game designed to teach math and science literacy skills to middle school students.

The game is played on a Dell Axim handheld computer and uses Global Positioning System (GPS) technology to correlate the students' real world location to their virtual location in the game's digital world. As the students move around a physical location, such as their school playground or sports fields, a map on their handheld displays digital objects and virtual people who exist in an augmented reality world superimposed on real space. This capability parallels the new means of information gathering, communication, and expression made possible by emerging interactive media (such as Web-enabled, GPS equipped cell phones with text messaging, video, and camera features).”

Although its being developed for high school students, it holds real potential for teaching such college-level subjects as environmental studies, architecture, and anthropology..

Canon Powershot S5 vs. Panasonic DMC-FZ8

I've been in a bit of a quandary ever since I went ahead and ordered the Panasonic DMC-FZ8 in time for my first New York trip even though I heard that Canon was coming out with a new Powershot High-Zoom camera soon after I would return. Today, I finally got around to reading Digital Photography's review of the new Canon Powershot S5 paying particular attention to the comparisons of ISO-Sensitivity and noise levels since my most demanding work is produced in museums without the benefit of flash or tripod. DPReview didn't provide a side-by-side comparison of Canon vs. Panasonic so I had to improvise:


My eyes are getting older these days but it looks to me like the Panasonic suffers from less noise than the S5 although there is a slight loss of detail. Actually, to be honest, the Sony DSC-H9 & Sony DSC-H5 seemed to have roughly the equivalent level of noise of the Panasonic with a little more detail than the Panasonic. All three appear to me to outperform the Canon S5 in this category.

As a former financial officer I also can't help but think about bang for the buck. The Panasonic cost me $269 compared to the Sony's $369 and the Canon's $469. The Panasonic is the only one of the three that can output in Raw format, has about twice as many scene modes, and weighs a mere 310 g compared to the Sony's 407 g and the Canon's 450 g. For someone like me with a problem with familial tremor, 100 -150 g can make a big difference especially if you couple that with one of the industry's leading image stabilization systems.

So, I guess I made the right choice for me based on my needs. I just wish Panasonic would be able to approach the High ISO quality output of the Fuji F-30. I have governed the Panasonic down to ISO-800 in my settings because the noise level is just totally unacceptable at the Panasonic's ISO settings higher than that. So, I keep my Fuji F30 with me too for those really dark exhibits.
