„Helen“ – Embodiment in Automobile Speech User Interfaces

Abstract

Embodied conversational agents may add value to speech dialogues within driver information systems. The experiment reported in this paper, compares a speech controlled driver information system developed by Blaupunkt GmbH with a prototype enhanced with a virtual character provided by Charamel GmbH. An expert evaluation and a usability study were conducted in order to determine whether an anthropomorphic interface leads to a more effective dialogue and to a higher level of user acceptance.
