Aspects of Voice Interaction on a Mobile Augmented Reality Application

Mobile Augmented Reality has become more popular mainly because computational resources available in mobile devices, and in the enhanced view of real world that can be seen by the user. The interaction becomes an important point for success of these applications, featuring a natural and intuitive way for the user, and the chance of one, or two hands free for other interaction or activity. Therefore, this work presents the usability analysis of a Mobile Augmented Reality, the ARGuide, with the use of a voice service for interaction. The usability test analysis is based upon the most common interaction tasks of the users in this type of application. In the end, some good practices for the application interface building and speech interaction are shown.
