Abstract
Embodied conversational agents that can sense and respond to multiple modalities of user communication, like speech, gesture, and facial expressions, create a better impression and facilitate communication [1,2]. Responding to a user’s gestures entails classifying the content and quality of each gesture, but classification performance is dependent on the selection of input sequence boundaries. Small changes in the boundaries of an input sequence can have a large effect on classifier output. Failing to correctly classify a user’s gestures may cause an agent to respond incorrectly, which can negatively impact the agent’s ability to communicate.
