Wearable computing provides huge opportunity for utility and expression. Once again, the primary target would be content for the Marketing industry.
Currently, wearable computing is thought of as electronics sewn into fabrics. These might glow or change colors based on sounds or heat, etc. This narrow view of wearable computing has slowed progress. I clearly demonstrated that wearable computing can be done with our current mobile devices - this was the Hangy project. Hangy as a mobidalion is one way. Devices can also be put in see-through pockets, sleaves, in backpacks, hats, etc. We now have old devices around - these can also be used. What we build for wearable expression is the next important step.
