The Learning and Teaching Expo 2023 in Hong Kong has come to a successful end. We are thrilled that our newly launched UnaGPT auto-grading and feedback system has attracted many teachers to try it out on the spot and received many enthusiastic feedback. The STEM/AI projects showcased, including the Smart Home, Virtual Escape Room game, and Real-time AI Pose Detection game, were also well-loved by students and teachers. We sincerely thank everyone for your participation and support! We would like to express special gratitude to the representatives from EDB, Ir. Tony Wong (JP, Government Chief Information Officer of OGCIO), Prof. Wong Kam Fai (MH, Member of the Legislative Council), and Mr. Ngai Yuen Keung (Executive Director of Hong Kong Education City) for visiting our booth. We would also like to thank Mr. Shing Wai Suen (ICT Panel Head, Hong Kong True Light College) for sharing his experience and the effectiveness of UnaGPT during the expo.We look forward to meeting you all again at LTE 2024 next year!
