gestures

Usability of bezel gesture actions for mobile?

This is a bit of a Hail Mary, but has anyone come across user testing or studies on the use of bezel gestures (i.e. swiping in from the left bezel onto the screen, or Microsoft's Edge UI)? I'm guessing MS must have done some testing but my Googling has proven useless in finding anything of use.

I'm trying to determine just how discoverable these types of gestures are, and trying to make a case for adding some kind of on-screen UI to surface functionality relegated to a bezel menu.

Kinetic Design (Core77 article)

for all you hardware interaction designers, this bit was just an
amazing piece on Core77 about Kinetic Design. I think some of us
might think this is just "interaction design", but to me the
discussion of aesthetics of motion really touches my heart string in
a wondrous way. There was this Pratt ID student I met a couple of
years ago who did his thesis on this, and it also really resonated
with me back then.

Touch is the new Click - Gestures are the new UI

Don't know if anyone of you saw the announcements in London two days ago? I
know its outside the US so it doesn't really count, but here is the heads up
anyway:

A mobile, open development platform with touchscreen, haptic feedback,
presence, GPS location, WiFI/VoIP and an AJAX capable web browser. Only
Google Gears is missing. Nokia showed a touch UI phone with a development
environment. It is not multi-touch, darn! The touch screen in the demo was a
resistive type single point touch screen.
