Enhancing E-Accessibility of Disabled People Using Low-Cost Technology

E-Inclusion of disabled people and implementation of a lot of e-services requires e-accessibility, which refers to the ease of use of information and communication technologies, such as the Internet, by people with disabilities. In order to enable computer access of disabled people and enhance e-accessibility, this work presents two devices based on low-cost technology to control the mouse cursor. Decoding upper-limb gestures from electromyography (EMG) could help to develop human-computer interfaces that increase the quality of life and e-inclusion of the disabled or aged people. Thus, was developed an EMG-based computer access device that use biological signals. Another device for computer access was developed based on inertial sensors, which allow capturing motion. From the Fitts' law test carried out, it was obtained an IP of 0.31 bit/s for the EMG-based computer access device and IP of 0.85 bit/s for the inertial sensor-based computer access device.
