Here we find another example of gesture recognition straight from the heavens above.
At Philips they tinkered a bit with Looking Glass and HandVu, and now they have got it: A gesture controlled home environment. Just the thing we will be needing if our future is anything like minority report. What strikes me most is that your gestures appear to be captured from above. You do not gesture at the camera but rather hold up your hands for inspection. It is a posture and not a gesture if ever the two are to be set apart.
I like the way they provided three different interaction means: gestures, touchscreen and mouse. That should provide people with options to explore their preferences. Speech and gesture recognition need not replace mouse and keyboard. Just add it and create multimodal interaction. (We will deal with those silly little integration issues later).
