Exploring Emely: An exploratory case study on the usability and user experience of a conversational agent for L2 learning

Abstract: This study focuses on evaluating and enhancing the user experience of Emely, a conversational agent aimed at improving language skills for second language learners, particularly those who want to increase their chances of securing employment in Sweden. Usability testing was conducted in two test rounds, with the first round providing design implications for the user interface in the second round. However, assessing the effectiveness of the interface improvements was challenging due to low Swedish proficiency among the test groups consisting of potential users of Emely. Although the study did not result in design implications for the user interface, important findings highlight the need to adapt conversational agents, like Emely, for users with low literacy levels and illiteracy, emphasizing the importance of inclusive design for effective language learning support.
