Modeling of the input-interface between an assistive device and an individual with disabilities

Abstract

Discusses the potential development and use of mathematical models in the design of assistive devices for individuals with disabilities. The man-machine or input interface between an individual with a disability and an assistive device was explored and modeled. An empirical lumped model used in the design of aircraft and automotive control systems was examined as an approach to the input-interface model. Advantages of this type of model along with an example of its application to a set of experimental data are discussed. Limitations of the present model, other types of models, and future directions as applied to rehabilitation engineering design are presented. In conclusion, the ability to utilize models in rehabilitation design can aid in the design process resulting in better, more efficient devices.
