Pointing accuracy was found to vary significantly with the type of device (F(3.2, 93.1) ¼ 3.937,
p ¼ 0.009) and the effect of the device on pointing accuracy was important (partial h2 ¼ 0.120). The most
accurate pointing was achieved when participants used the joystick. Using the joystick, a mean of 96.8%
(SD ¼ 4.3%) of pointing trials resulted in the correct orientation. If only diagonal orientations are
considered, the correct pointing rate increased to a mean of 99.5% (SD ¼ 1.5%) when using the joystick
