I doubt you’ve been tungsten gas welding recently, but it turns out it’s a demanding process. A set of University Toronto researchers (among them wearable computing pioneer Steven Mann) write in an abstract that tungsten inert gas welding requires “more skill and more visual acuity than most other welding processes” and that “keen eyesight and exact hand-eye coordination” are a must. As if tungsten welding weren’t difficult enough, recording tungsten welding is just about impossible. A state-of-the-art digital camera is unable to properly adjust itself to capture an image of the site of welding–the brights are far too bright, and the darks are far too dark. What’s needed is a camera system with a far wider dynamic range, a virtual eye that can take in the high highs and low lows all at once. Mann et al. have built just that, and will be presenting their stereo “EyeTap welding helmet” at this year’s Siggraph conference.
