Embodied interface agents are considered to be a promising interface metaphor of the future since they are widely expected to facilitate HCI and trigger natural communication. Although first evaluations indicate that virtual characters have various strong effects, it is still unknown if and how embodied conversational agents affect the way in which users communicate with the technological system. An experimental study was conducted to analyze if users interact differently when confronted with different kinds of interfaces (GUI, speech output, embodied interface agent) of a TV-VCR-System. 65 participants were asked to solve different tasks choosing either natural speech or remote control as input devices. Results show that a system is significantly more often addressed by natural speech when an embodied interface agent is visible. Additional qualitative analyses of the semantic content of all 943 speech acts indicate that users seem to have a more human-like attitude and behavior towards the system when it is represented by an anthropomorphic agent.
