Description WIISEL's main goal is to develop an unobtrusive, self-learning and wearable prevention and warning system to decrease the incidence of falls in the elderly population.The idea is that elderly people put a specifically designed insole in their shoes, which monitors their walking pattern. This way the system may detect changes in gait and balance in the daily environment of the older person, which helps predict the likelihood of falling. Thanks to a wireless system and chips built into the insole, data captured by the movements of the foot are sent to a mobile device or computer, so that the doctor, caregiver, nurse or administrator can follow the evolution of the patient, to assess if he correctly follows the rehabilitation programme or if he returns to bad habits that increase the risk of falling. If this occurs, an alert is sent immediately to the responsible caregiver. Thus the system provides security to the elderly and reduces their fear of falling, directly improving their quality of life.
