title: Background luminance and input devices on clicking performance with a tablet PC.
abstract: This study investigated the effects of input devices and background luminance on clicking performance with a Tablet PC. The experiment was designed in complete block design within subjects. Participants were 19 men and 11 women, college students whose ages were 19 to 22 years (M=20.1 yr.). All had 0.8 corrected visual acuity or better and normal color vision. Three kinds of input devices, mouse, light pen, and touchpad, were used in this experiment. An analysis of variance showed that input devices significantly affected clicking performance as did background luminance (contrast ratio) on visual recognition (a higher contrast ratio gave better visual recognition).
