The 14-item questionnaire uses a 10-point Likert scale, ranging from 0 (strongly disagree, very poor, very uneasy, and very unsatisfied) to 10 (strongly agree, very good, very easy, and very satisfied)
The Usability of the chatbot, as measured by the System Usability Scale
时间窗: End of study (2 months)

The result of this survey is called SUS score, which ranges from 0 to 100 and provides information about overall customer satisfaction and usability. A higher score indicates better usability, while a lower score may suggest usability issues.
The user experience, as measured by 10 open-ended questions
