One of the distinguishing differences between the Pre and regular smartphones is its Gesture Area, below the screen, highlighted below:
It’s bilateral, separated by the center button which invokes the Card View.
We’ve seen three gestures demonstrated.
Back, which I’ve illustrated on the left side above. It can also be done on the right side of the Gesture Area, with the same leftward swiping movement.
To invoke the Wave Quick Launcher, begin in the Gesture Area and swipe and hold towards the interior of the screen. Again, this can be done on the right side too.
To call up the full Application Launcher, begin in the Gesture Area and swipe and lift inside the screen. As well, it can be done on the right side.
Those are the three Gestures we’ve seen.
Are others possible?
What about this:
Two fingers beginning at the outer edges of both left and right sides and moving inward?
Two fingers beginning near the center button on both left and right sides and moving outward?
For that matter, what about using the Gesture Area for tapping?
No, don’t ask me what these other possible gestures could be used for. That’s up to application developers — if Palm hasn’t already reserved those movements.
