Query: Monitoring the Mental State of Cooperativeness for Guiding an Elderly
  Person in Sit-to-Stand Assistance   In providing physical assistance to elderly people, ensuring cooperative
behavior from the elderly persons is a critical requirement. In sit-to-stand
assistance, for example, an older adult must lean forward, so that the body
mass can shift towards the feet before a caregiver starts lifting the body. An
experienced caregiver guides the older adult through verbal communications and
physical interactions, so that the older adult may be cooperative throughout
the process. This guidance is of paramount importance and is a major challenge
in introducing a robotic aid to the eldercare environment. The wide-scope goal
of the current work is to develop an intelligent eldercare robot that can a)
monitor the mental state of an older adult, and b) guide the older adult
through an assisting procedure so that he/she can be cooperative in being
assisted. The current work presents a basic modeling framework for describing a
human's physical behaviors reflecting an internal mental state, and an
algorithm for estimating the mental state through interactive observations. The
sit-to-stand assistance problem is considered for the initial study. A simple
Kalman Filter is constructed for estimating the level of cooperativeness in
response to applied cues, with a thresholding scheme being used to make
judgments on the cooperativeness state.
