Abstract

Finger-operated soft keyboards have recently appeared in mass-market products such as the Apple iPhone. These keyboards have a function that shows a zoomed version of the selected key enlarged and offset above the finger (hereafter zoom) so that the user can see the key under the finger. This function is often combined with a dictionary for automatic error correction. We wanted to measure the benefits of the zoom. The reason for this was that it does not do anything to the motor space in which the finger operates and therefore the performance benefits were in doubt. Even performance degradation could happen due to the need to process more visual feedback. We tested the zoom in a text entry experiment. After basic tests of finger accuracy and touch screen reliability, we compared a keyboard with and without the zoom. There were no clear differences in text entry rate and error rate. While not statistically significant, differences in user responses seem to indicate that the visual feedback of the zoom function is appreciated.
