Abstract

In this article, we present a study on the user’s gaze tracking during a text input task on a soft keyboard associated with a word prediction list. The purpose of this study is to investigate user strategies for using the prediction list. When does he watch it? How frequently? Does he look at the whole list? our first results shows that the user only looks at the top of the list. Therefore, it does not use the prediction list optimally and enters more characters on the soft keyboard. Moreover, typing on the soft keyboard is also penalized by the presence of the list next to the keyboard because the user looks at it without necessarily using it. This sub-optimal use of the list coupled with slower input on the soft keyboard therefore results in a slower average input speed on the soft keyboard associated with a list.
