Abstract

A wearable, wireless and multimodal 2-dimensional computer mouse control system is introduced for people with upper-body disabilities. The system combines body-motion, measured using inertial measurement unit (IMU), to provide a cursor velocity and displacement control, and surface electromyography (sEMG) for target selection (left-click), using custom sensors made of electronic components of the shelf. It is demonstrated by using head motion and muscular activity detection from trapeze muscles to evaluate usability by people living with severe disabilities, congenital absence or amputation of upper-members, temporary limb traumatism, etc., preventing their utilization of tools such as mouse or keyboard. Performance using different control topologies, following the ISO/TS 9241-411:2012 standard encompassing the evaluation of physical pointing tasks, and compared to a computer mouse.
