The firm Elliptic Labs has developed a prototype for touchless user interfaces which is easier to implement and cheaper than today used camera-image-based technology and utilizes ultrasound. I like this “hand gesture – in / out (play / pause)”.
This can be a cool technology. Imagine to sit on the sofa watching a film and just have to use this gesture “out / pause” to hold the film. It’ll be something like “Minority Report” (again).
But what’s with animals (especially pets)? For example dogs can hear these (ultra)sounds and I think it’ll hurt them! Or will this attract bats to come around?
