Abstract

A study was conducted to determine the benefits of adding voice input to the graphical user interface (GUI) of a geometry learning software (Cabri-geometry II). In particular, we aimed to test whether or not voice input has an advantage over mouse input, regarding speed and user's preference. An experiment was conducted on 8 students aged between 15 and 16 who interacted with both the standard interface (mouse/keyboard) of the software and a multimodal interface in which speech recognition was simulated by the "Wizard of Oz" technique. The results show that voice input is significantly faster than mouse/keyboard input for command completion and that students prefer using voice commands rather than mouse/keyboard or multimodal commands.
