We present a new technique called ‘Tilt Menu’ for better
extending selection capabilities of pen-based interfaces.
The Tilt Menu is implemented by using 3D orientation
information of pen devices while performing selection tasks.
The Tilt Menu has the potential to aid traditional one-
handed techniques as it simultaneously generates the
secondary input (e.g., a command or parameter selection)
while drawing/interacting with a pen tip without having to
use the second hand or another device. We conduct two
experiments to explore the performance of the Tilt Menu. In
the first experiment, we analyze
the effect of parameters of
the Tilt Menu, such as the menu size and orientation of the
item, on its usability. Results of the first experiment suggest
some design guidelines for the Tilt Menu. In the second
experiment, the Tilt Menu is compared to two types of
techniques while performing connect-the-dot tasks using
freeform drawing mechanism. Results of the second
experiment show that the Tilt Menu perform better in
comparison to the Tool Palette, and is as good as the
Toolglass.
