@inproceedings{Roy2021_Tasks_and_CAs, abstract = {Conversational Agents (CA) have become one of the common user interfaces in many online domains. In this paper, we ask whether users have a preference about the personality of CAs, and whether this preference changes depending on the length and type of the tasks CAs are used for. In an online study (N = 410), we investigated three different CA personalities (introvert, extrovert, and non-personified) in four different tasks with different natures and lengths (teaching, booking, todo, and weather). Most of the participants preferred to interact with a conversational agent (introvert or extrovert) as opposed to a non-personified interface, regardless of their own personality. Results suggested that this preference may be task dependent: when CA\textquoteright{}s goal was to provide information, participants preferred an extrovert agent. We did not observe a difference between the preference for introvert and extrovert agents when the task\textquoteright{}s goal was to complete an assignment. }, author = {Roy, Quentin and Ghafurian, Moojan and Li, Wei and Hoey, Jesse}, booktitle = {Proceedings of the 9th {International} {Conference} on {Human}-{Agent} {Interaction}}, isbn = {9781450386203}, date = {2021-11}, pages = {174--182}, pagetotal = {9}, location = {New York, NY, USA}, publisher = {Association for Computing Machinery}, title = {Users, {Tasks}, and {Conversational} {Agents}: A {Personality} {Study}}, url = {https://doi.org/10.1145/3472307.3484173}, }
