N2 - Touch accuracy is not just dependent on the performance of the touch sensor itself. Instead, aspects like phone grip or occlusion of the screen have been shown to also have an infuence on accuracy. Yet, these are all dependent on one underlying factor: the size and proportions of the user's hand. To better understand touch input, we investigate how 11 hand features infuence accuracy. We find that thumb length in particular correlates significantly with touch accuracy and accounts for about 12 % of touch error variance. Furthermore, we show that measures of some higher level interactions also correlate with hand size.
