Abstract:
This paper presents results of an experimental study of
unconstrained line-tracing task with use of mouse, pen- and
touch-input. Our results show that participants using touchinput
performed as good as with use of mouse in terms of
similarity of reproduced shape with pen-input as the best tool
for drawing. Touch-input users were also the fastest in
comparison to the remaining input methods. Additionally, we
have observed subjective operational biases that together
with shape-related issues might have an influence on the
final scores.
