On the great trip from East to West I had the pleasure to visit UC Boulder. Katie Siek was so kind to introduce me to Shaun Kane and I had the pleasure to meet Swamy Anantharanayan as well als Halley Profita on my short visit in Boulder. Halley showed me prototype of her wonderful work on the award winning tactile display Flutter – a wonderful garment that is instrumented with a fashion-oriented wearable tactile display. Swamy Anantharanayan showed me the Human Centered Computing Lab and the interesting work and prototypes in the lab. It was very interesting to own work on „crafting of personal health technologies“ and his thesis that is just about to be submitted.
