I thought that would be trivial. If I recall correctly DOOM can be
controlled in two ways: accelerometers or TS. When controlling with
the TS you constantly press down on the TS with a finger, and "tilt"
your finger to the direction in which you want to move. Found an
example of it on youtube:

zooming in could be done by tilting the finger forward
zooming out by tilting the finger backwards

maybe i'm overlooking something here...
to make it work good in a webbrowser (which is filled with clickable
object like links) the "click event" should occur on "finger up"
though, not on "finger down"
