Breaking of the dawn jacket: light in the Arctic Winter

Wearable computing for the winter context is so far little explored. As well as low temperatures, winter brings the contrasts of darkness, and bright snow-reflected sunlight. We present the Breaking of the Dawn winter jacket, which detects the ambient light level and utilizes LEDs to light the darkness. Thermochromic ink patterning on the jacket dynamically changes, to inform the wearer of high UV light levels. The garment is made from reindeer leather, reflecting the traditional reindeer herding industry of the Arctic areas.
