Researchers created a special empty frame with highly responsive multi-touch capacity.

Touch-sensitive frames have enabled surfaces to become interactive for years, but their size and responsiveness tend to be limited.

Put ZeroTouch on a computer screen and it turns into an interactive surface that can be manipulated with a stylus.
