With a single piece of inexpensive hardware — a multicolored glove — MIT researchers are making Minority Report-style interfaces more accessible.

“This actually gets the 3-D configuration of your hand and your fingers,” Wang says. “We get how your fingers are flexing.”

If we were to combine simple hardware like this with simple pitch/rythm based computer voice interface dialect, we could make some really phenomenal human/computer interfaces.
