Introduction of soft computing techniques to welfare devices

This paper introduces our research into the use of soft computing techniques for hearing impairment compensation and physical rehabilitation. Evolutionary computation (EC) is used for fitting hearing aids based on an interactive EC and the user's preferences for sound. This technology allows hearing aid users to optimize their hearing aids in any acoustic environment without professional assistance. The virtual reality (VR) system for physical rehabilitation allows patients to train their muscles and reflexes according to the level of their physical condition.
