Four-Diagnoses Auxiliary Apparatus based on Chinese Medicine in Health Evaluation and Constitution Identification

The understanding of health has deepened with social development, scientific improvement, and environmental changes. The focus has changed from disease-oriented to health-oriented viewpoint. Hence, it is important to evaluate health using objective and accurate criteria. The four-diagnosis methods and syndrome differentiation are focused on differences among individuals according to the yin, yang, qi, and blood conditions. These differences are closely related to the constitution of a subject. The promotion of constitution identification among healthy and subhealthy groups and patients is beneficial for subjects to understand their body characteristics. It is important in daily health cultivation and disease prevention. Digital and objective information of a subject is acquired by the traditional Chinese medicine (TCM) Four-Diagnosis Auxiliary Apparatus efficiently and accurately. The automatic extraction and recognition of all the information is an important step in the diagnosis and constitution identification process by TCM.
