One of the concerns for an N9 owner is the lack of a dedicated hardware key or shutter for the camera. We now have to hunt around in the app-launcher screen to find the icon and click it to open the camera. I am thinking about alternate launching mechanisms.

IIRC, the double-tap to unlock feature of the N9 is based on the accelerometer, which detects the direction of the tap and if in the direction of the screen, unlocks it. What I am proposing is to harness this feature.

ie, Double taps on the back of the device (as opposed to the screen) should automatically launch the camera, irrespective of whether it is locked or unlocked.


Will this be possible? Is the module responsible for this behaviour open or closed? How difficult will it be to implement this? Developers, it would be great if you could answer!
