A camera-collar lets you vicariously swim and frolic and eat raw fish.
Meet Tasul, a polar bear at the Oregon Zoo taking part in a research project to help zoologists understand polar bear behavior (and maybe, by extension, strategies for preserving the species). Tasul wears an accelerometer, which reports on the bear's movements, along with a collar that has an Go-Pro attachable camera, giving researchers a first-person view of what Tasul sees. The researchers want to measure how Tasul reacts to environmental changes and, after this in-zoo trial run, will try out the project on wild bears, which we sincerely hope they release video of, too.
