Study on Text-based and Voice-based Dialogue Interfaces for Human-Computer Interactions in a Blocks World
Sujeong Kim, David A. Salter, Luke DeLuccia, Amir Tamrakar · 2020
We conducted a small scale user study to understand user experiences with two different forms of dialogue interfaces - text-based and voice-based - to interact with a virtual agent in a Blocks World environment while perform tower building tasks. The participants also had the option of using deictic gestures in addition to the speech modality. We identify common types of errors/issues that led to communication failures and share our observations about how users reacted to these issues. We also present survey data that reflects users' evaluations of the dialogue interfaces and their interactions with the virtual agent.
