One of the focuses of our sustainable campus should be the working and study qualify of our university members. As the most common posture is sitting in front of a desk during our campus life, most people sit down for terribly long periods of time, while the current pandemic situation worsens it even more. Long-time sitting and the improperly sitting posture could result in fatigue, low working efficiency and bring harm to our health gradually. It is smart to have a mechanism to maintain a healthy sitting habit and protect our spine and body. Combining our previously patented soft sensor technology and sensor fusion AI technology, the students will assist researcher to develop a smart cushion system to monitor and learn our sitting habits and present us with stand-up reminders (vibration of the cushion), posture advice, and tailored stretching guidance through smartphone or computer.
