I used one of those leap motion controllers once, but then I spent a few minutes watching someone else use one and I realised several things that seem equally important to me:
1) moving your hand away from a keyboard to perform gestures not that much richer than a trackpad isn't as transformative as it seems, or very efficient
2) how they feel to interact with does not balance well with how they look to interact with, away from a gaming type context. How it feels: peculiarly magical, like casting spells. How it looks: D&D wizard excitedly miming his spells at the table-top, to the annoyance of his party.
3) there's really very often a beverage on my desk in a way that is at odds with me -- a clumsy type -- waving my hands around enthusiastically.
The only use I ever really found for my Leap was to control iTunes when I was in the middle of bleaching or dyeing my hair and didn’t want to touch the keyboard. It was great for that.
I say “was” because the tool I was using for this no longer supports the Leap.
I'd be happy to wave gestures for stuff that people normally use Alexa/Siri for, because while I talk to myself out loud all the time, talking to a computer is weird.
But it's fascinating isn't it how the Leap was going to be everything and then within a year or two it's discounted in Maplin.
