Summary: Current automotive interfaces rely heavily on touchscreen interfaces which
leverage simple and intuitive direct touch interaction. Since input and output
are co-located, displays have to be positioned within hand's reach. When the
display is outside the reach envelope, a touchpad has been used as a control
device. Current implementation of touchpads in cars rely on a relative input
method that requires a visual cursor and is known to cause distraction from
primary driving task. Newer touchpads with force sensing ability are getting
introduced in notebook computers. We propose to use a force-enabled touchpad
with absolute mapping for target selection. We performed a controlled
experiment as a first step towards assessing whether absolute mapped force
input target selection performance can be comparable to direct touch input.
Results show that target selection performance is not significantly different
from direct touch input making a case for force-enabled touchpad usage in
scenarios where the display is outside the reach envelope.
