Importance of bio-signal for rehabilitative engineering

Abstract

Use of Bio-signals in the field of Rehabilitative engineering places a vital role in enhancing the quality-of-life (QOL) of individuals with several levels of disabilities. Assistive devices like motorized wheelchairs for lower-limb disabled persons, smart canes for visually impaired persons, hearing aids, robotic hands (or bionic arm) for the amputee, etc. are invented in order to improve the QOL of individuals with several levels of disabilities. Rehabilitative aids are mainly intended to assist the disables, so it is essential to have accurate and adequately functioning aids/devices with user-friendly manner, which can be made possible by interfacing Human-computer/machine (HCI or HMI) with proper feature extraction and computation models. Moreover, combining electrical bio-signals with non-electrical bio-signal will gradually increase the level of accuracy, but it will load the work of computational algorithm. © Springer Nature Singapore Pte Ltd. 2019.
