Abstract

Last decade has seen the democratization of small sensitive devices. But text entry solutions remain faithful to the AZERTY/QWERTY layout or to the 12-key mobile phone keypad. We propose SlideKey which is based on FOCL from Scott MacKenzie. The technique uses a linear keyboard whose layout changes according to probablities. Key selection is operated thanks to four directional keys. SlideKey integrates a pre-visualisation of the two-next layouts to ease user to planify his next interactions. Preliminary tests show a not significant gain in performance when pre-visualisation is used.
