Uni-model human system interface using sEMG

Today's high-end computer systems contain technologies that only few individuals could have imagined a few years ago. However the conscious input device ergonomics design is still lagging; for example, the extensive usage of computer mouse results in various upper extremity musculoskeletal disorders. This endower towards the developed of HSI system, that act as an alternative or replacement device for computer mouse; thereby one could avoid musculoskeletal disorders. On the other hand, the developed system can also act as an aid tool for individuals with upper extremity disabled. The above issue can be addressed by developing a framework for Human System Interface (HSI) using biological signal as an input signal. The objective of this paper is to develop the framework for HSI system using Surface Electromyogram for individuals with various degrees of upper extremity disabilities. This framework involves the data acquisition of muscle activity, translator algorithm that analysis and translate the EMG as control signal and a platform independent tool to provide mouse cursor control. Thus developed HSI system is validate on applications like web-browsing, simple arithmetic calculation with the help of GUI tool designed. © 2011 Springer-Verlag.
