The invention relates to the technical field of health care, and discloses a bath chair self-adaptive adjusting
system based on multi-
modal sensing. According to the
system, a
pressure sensor array, an
infrared thermal imager and an
inertial measurement unit are used for collecting multi-dimensional real-
time data, and the multi-
modal sensing fusion module is used for
processing the multi-dimensional real-
time data to generate a structured physiological
feature vector. The user intention recognition module predicts user behavior intention and gives a comfort level
score on the basis, and the posture self-adaptive adjustment module optimizes seat supporting curved surface parameters according to the comfort level
score to achieve real-time adjustment. In addition, the
safety monitoring module evaluates the slip risk, the closed-
loop control module guarantees safety, the
online learning module optimizes the adjustment strategy, and the abnormal response module deals with the emergency situation. According to the
system, the comfort and safety of the bath chair are improved, personalized adjustment is achieved, and the system has high practical value.
