The document proposes an architecture for a fast diagnosis system in an ubiquitous society. The system works as follows: (1) A mobile agent detects body disorders and automatically diagnoses the patient. (2) It collects health data from the patient including medical records and environmental factors. (3) It finds an appropriate doctor to analyze the data. (4) The agent provides diagnosis results to the doctor for confirmation and treatment. (5) It orders medicine or emergency services, and summarizes causes to avoid future illness. The system aims to detect issues early, find the best doctors, and deliver healthcare conveniently to patients.
