Teacher-student interaction (TSI) is essential for learning efficiency and harmonious teacher-student interpersonal relationships. However, studies on TSI support tools often focus on teacher needs while neglecting student needs and autonomy. To enhance both lecturer competence in delivering interpersonal interaction and student autonomy in TSI, we developed NaMemo2, a novel augmented-reality system that allows students to express their willingness to TSI and displays student information to teachers during lectures. The design and evaluation process follows a new framework, STUDIER, which can facilitate the development of theory-based ethnics-aware TSI support tools in general. The quantitative results of our four-week field study with four classes in a university suggested that NaMemo2 can improve 1) TSI in the classroom from both teacher and student perspectives, 2) student attitudes and willingness to TSI, and 3) student attitudes to the deployment of NaMemo2. The qualitative feedback from students and teachers indicated that improving TSI may be responsible for improved attention in students and a better classroom atmosphere during lectures.
