Standard input devices for mobile phones are directional keys and
discrete thumb-joysticks. These devices are dedicated to the discrete GUIs of the phones
(eg. scroll lists and small icons arrays). Today, new mobile
applications are arising and require adapted interfaces. In
particular, the widespread of 3D applications will be favored if
users can efficiently point on any part of the
screen. In this paper, we propose a new interaction technique called
''Jump and Refine'' for selection tasks on mobile phones. This technique is based on
two levels of cursor displacement in order to reduce the number of
keystrokes. The first level allows fast movements into an underlying
grid. The second one can be used for accurate positioning into
the selected area. We present a user study which shows that using a
first coarse ''jump'' level decreases the selection completion
times. The study also shows that the technique is widely accepted by
the users. Finally, we discuss the optimal grid sizes.
