A novel approach for human fall detection and fall risk assessment

摘要: There are several studies concerned in providing quality health care services to all people. Among them, human fall detection systems play an important role, because fall is the main obstacle for elderly people to live independently and it is also a major health concern due to aging population. The three basic approaches used to develop fall detection systems include some sort of wearable, ambient or non-invasive based devices. Most of such systems are very often rejected by users due to the high false alarm and difficulties in carrying them during their daily life activities. Thus, this study proposes a non-invasive fall detection system based on the height, velocity, statistical analysis, fall risk factors and position of the subject from depth information. The proposed algorithm also utilizes fall risk factors of the user, during fall detection process to classify the subject with chances of fall such as high fall risk or low fall risk …
