title = "A Study on Touch Screen Numeric Keypads: Effects of Key Size and Key Layout",
abstract = "The demand for touch screen displays, from personal mobile devices to public self-service kiosk, has drastically increased since last decade. Touch screen kiosks normally involve numeric data entry for functioning, underlying the necessity for optimizing the design of numeric keypads for improved performance. The present study was thus conducted to investigate the effects of key size and key layout for numeric keypads with a numeric data entry task. The results showed that keying performance was affected by both key size and key layout, and the effects of them in terms of entry speed, accurate rate and completion rate were discussed.",
