> What do I do to make psmove work like a mouse?
There is no feature (neither in the PSMove controller nor in psmoveapi)
that magically enables such a feature.
You would have to define how exactly movement of the controller is
supposed to affect your mouse cursor (for instance: tilting the
controller left/right moves the mouse cursor left/right, or maybe you
actually want it to behave more like a laser pointer, moving the mouse
to where you are pointing the controller at on the screen) ... and then
program a driver that implements this behaviour.
psmoveapi gives you the controller's sensor data and, if you are using
the camera tracking of the glowing orb, its position, but you have to
implement the actual mouse behaviour yourself on top of that.
