I was about to say the same. The hand gesture control is the new "drag and drop" that was overhyped back in late 1990s.

While "drag and drop" has its uses today, it's nowhere as ubiquitous as its proponents back then wanted. Back then, it was forcefully pushed into spaces where it didn't belong.

Same for the gesture controls. Damn you, Minority Report, for putting this idea into the heads of the software business people. It's not all slick hand waving in the air.
