From vocal to multimodal
Marc Mersiol · 2003
This paper presents a study conducted on fifteen users. The latter carry out scenarios using three vocal services. Each service is used in its commercial version and in a version providing added textual information. This information is partially redundant with audio information delivered by the vocal services. The aim of this study is to check to what extent this added information modifies use of these services. The main results show that displaying text is favourably accepted by the users, but does not modify the completion of the scenarios.
