The folks at Carnegie Mellon’s Future Interfaces Group have made something really cool. Essentially, they are using small lasers to paint icons onto your skin through the bottom of a watch. The icons are touch sensitive and can be projected in any shape.
The team consists Gierad Laput, Robert Xiao, Xiang Chen, Scott E. Hudson, and Chris Harrison, researchers at CMU’s Human-Computer Interaction Institute. Interestingly, the project is similar to the “debunked” Ritot smartwatch although this project displays the icons and information in bright red.
From the project document:
These sorts of interface tricks are quite interesting. By expanding a watch interface off of the physical object you get a bigger palette on which to create and you reduce the need for text and icons on the screen. It’s great for folks who can’t see well – the icons can be as big as needed – and it’s also a nice way to expand the field of interaction without making the screen bigger. Could we soon see an Apple or Android with a powerful holographic laser system inside? I hope so!
