A sub-health self-check system using image information of eye expression

In the modern society, people live in a state of tension and have great pressure; their bodies are often sub-healthy. The western medicine is expensive and hard to self-check sub-health at home. The Traditional Chinese Medicine (TCM) can diagnose sub-health and can prompt patients their coming disease. This paper describes an experimental sub-health self-check system, which is simple and low-cost. This paper introduces emphatically how the system uses image information of eye expression as its input.
