As cellular phones get smaller, there has been a concurrent reduction in the size of the control interface. Two studies examined whether tactile cues might facilitate dialing on small cellular phone keypads. The first study, a questionnaire administered to 289 individuals, suggested that people believe that tactile cues can benefit users of cellular phones. The second study, an experiment comparing dialing performance with vision precluded between two keypad-types (textured keys and smooth-keys), showed that performance in the former condition was better than that latter. Implications for cellular phone keypad designs are offered.
