Abstract

This paper presents the development of a character activation time prediction model for tongue-typing. This model is based on a modification of Fitts´s law that is more suitable for tip-of-tongue selectivity tasks around the palatal area. The model was trained and evaluated with data from tongue-selectivity experiments using an inductive tongue-computer interface. It takes into account the movement amplitude, target position, interactions between them, character disambiguation time and error correction time.
