“…Our Semantic Keyboard uses a character prediction system based on a lexical tree [2]. When the user enters a prefix, the prediction system classifies letters by their probability of occurrence and then associates an enlargement coefficient with each key.…”

“…They typically lead to a static or dynamic reorganization of the keyboard or other improvements considering co-occurrence. A well known technique is to provide a completion list [2], [7] to reduce the number of actions to input a word. However, every solution is a compromise: New layouts are hard to learn; dynamic changes increase cognitive load and completion lists are often used inefficiently.…”

Abstract. In this paper we describe Semantic Keyboard: a soft keyboard augmented by semantic pointing. The cursor crosses faster over keys containing low-probability letters (considering the prefix already entered). This optimization reduces the movement of the pointer by 60%, and increases the text entry speed by 13.5% after the first character in a word. Accuracy is equivalent to a regular soft keyboard.

Last decade has seen the democratization of small sensitive devices. But text entry solutions remain faithful to the azerty or qwerty layout or to the 12-key mobile phone keypad. We propose SlideKey which is based on FOCL. It uses a linear keyboard whose layout changes according to probabilities. Key selection is operated with the four directional keys. SlideKey integrates a preview of the two-next layouts to ease user to planify his next interactions. Preliminary tests show a not significant gain in performance when the preview is used.
