I always have a kind of negative reaction to these sorts of interfaces.
What I tend to see in this demo is how to make a doorknob unintuitive, how to make music player functionality undiscoverable, how to accidentally lock yourself out, how to frustrate a user whose mental model of the sensor is incorrect.
I realize you have to approach new technology and interaction paradigms optimistically, but all I can think of is my own frustration when an ill-considered neato-feature is foisted on me when I least want it.
Like blue LEDs and touch sensitive buttons that lack a physical button (eg atmel q-touch).
