Suggestions for Interface Design Using Head Tracking and Voice Commands

Abstract

Multimodal Interactions have been used in many fields of application, such as medicine, manipulation of assistive technologies, interactions in public environments, among others. It is important to not only develop technologies (hardware and software) but to study and project optimization possibilities for the usage of these innovative interfaces as well. This work aims to identify which are the major problems when using head tracking interactions combined with voice commands, this being a multimodal interaction. This evaluation is focused in the lowest level of interaction, which are actions more physical and less cognitive, such as click, drag and drop, scroll a page, among others. Therefore, as consequence of this research, there were proposed some suggestions to improvement of interface projects that use this form of interaction.
