Abstract  Falls in the elderly population is a very common phenomenon because of the limitation of age and physical condition. Therefore, it is important to remote monitor the elders state real time according to the movement characteristics of falling down, in order to take actions in time when elderly people fall down in some emergency situations. Characteristics of human body kinematics were analyzed in view of the human movement state monitoring, and an algorithm that fall detection based on extreme learning machine (ELM) was proposed. The method is to collect the body’s 3D acceleration value through a sensor. Then the model of fall detection was established. On the basis of the model, a fall detection classifier based on ELM was established and the computer aided detection for falls was completed. The 540 samples of experimental data were obtained, 440 samples for training and 100 samples for testing. The accuracy of the method was 93%, the sensitivity was 87.5%, and the specificity was 91.7%. Results show that the established method has good classification performance and advantages on the running time for classification of training in reference to the conventional machine learning.
