A square box (size: 50 × 50 pixels) was shown on the
screen and was randomly moved to new position whenever a
user clicked in this square. For the four different types of
mouses (a general mouse, Camera Mouse, Quick Glance, and
the proposed mouse), we measured the time required for
clicking the box 20 times. The results were as follows: general

proposed mouse is slower than the general mouse but is faster
than the other mouse, as shown in Fig. 5. When we consider
