Usability and Adherence
To evaluate the usability and adherence of HB-CCT, we conducted observations and collected user feedback. When users encountered difficulties or issues while using HB-CCT, we identified improvement points through phone or video calls based on their feedback. Additionally, administrators monitored the usage of HB-CCT to ensure smooth usage and identify any issues. We also confirmed the participation frequency, the average training stage, and average problem-solving speed of the HB-CCT groups in each session.
