Scanning-based human-computer interaction using intentional muscle contractions

Abstract

It has already been shown in the past that it is possible to leverage tiny muscular contractions produced at will (e.g., by frowning) in order to give someone complete control over a PC [1]. The underlying interaction technique is ideal for persons with severe motor impairments who are in need for an alternative, non-standard way to operate a computer. This paper deals with a scanning-based computer application of that approach to enable its user to control the immediate environment, e.g., by making a phone call, toggling the lights, or sending particular Infra-Red (IR) remote signals. Although the software is primarily targeted at people with disabilities, it is ready - and (in certain situations) even expected - to be used by able-bodied individuals as well. A user study evaluating the remote control module of the system has been conducted with twelve non-impaired subjects, and the results are discussed herein. © 2009 Springer Berlin Heidelberg.
