Summary: The tilting operation has been shown to be useful in expanding the input
vocabulary of a small device; therefore, this operation could also be useful in
expanding the input vocabulary of wrist-worn devices. In this study, in order
to explore new design guidelines of GUI and operation methods for smartwatches,
we have investigated the accuracy of the tilting operation for smartwatches. We
conducted an experiment using a cursor whose position is determined according
to the direction and angle of tilt. The result shows that the deviation in the
x-axis (i.e., the inclination of the arm) direction ranges from -0.10 degrees
to +0.07 degrees and from -0.10 degrees to +0.07 degrees under Seating and
Standing condition, respectively; the deviation in the y-axis (i.e., the
rotation of the wrist) direction from -0.12 degrees to +0.10 degrees and from
-0.12 degrees to +0.09 degrees.
