The process of taking my hands off the keyboard to wave them in the air to perform a gesture which I could do just as easily with keyboard shortcut, however, seems counterproductive. This is part where the Leap controller starts feeling like a novelty device. There are, however, times that I sit in front of my computer and I don’t have my hands on the keyboard. For instance, when I dictate.

This is the key to making something like Leap Motion Controller work well. I'm looking for how it might be used for presentations, where I'm similarly unlikely to sit down and use a keyboard.
