A coat of conductive paint can transform regular walls into giant touchpads   In Digital Trends By Luke Dormehl

The late Mark Weiser, the former chief scientist at Xerox PARC, once stated, “The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it.” Few tech projects summarize that vision of ubiquitous computing better than a new project carried out by researchers from Carnegie Mellon University and Disney Research. Through the use of conductive paint and some low-cost electronics, they have found a way to transform regular, boring internal walls into smart infrastructure able to detect human touch. .... "
