A smart environment (SE) is an Assistive Technology (AT) resource that allows people with motor disabilities, even with low mobility, to control the lighting and electronic equipment (TV, radio, fan, etc) of the environment through a Human-Machine Interface (HMI) configured to be activated by biomedical signals. However, despite the recognized importance, the AT resource is not always considered useful, reaching high abandonment rates, since a prior assessment and prescription by professionals is necessary, taking into account the real demands and needs of the person with disability. This Doctoral Thesis aims to evaluate the effectiveness of a smart environment system controlled by surface electromyography and by infrared oculography, captured by an eye tracker, used by people with motor disabilities. Six volunteers participated in the research, and, initially, were applied socio-demographic data forms, Functional Independence Measure (FIM TM) and Canadian Occupational Performance Measure (COPM). The subjects were presented to the equipment and system interface, being trained for their use in domestic environment, using the system for a week. Afterwards, they were re-evaluated with the COPM, besides evaluations of satisfaction with the use of the AT resource (form B-QUEST 2.0), psychosocial impact (form PIADS), usability of the system (SUS form) and semi-structured interview for suggestions or complaints. The control of TV was the common demand of all participants. As a result of this research, of the six volunteers, four used the system, presenting positive results regarding the change in occupational performance, satisfaction with performance and the smart environment system, high psychosocial impact and good system usability. It was evaluated that the developed system also provided greater independence of the volunteers for the control of the equipment. Regarding the volunteers who did not use the system, aspects such as nonacceptance of the disability and lack of social support may have influenced. The SE system proved to be effective, improving all aspects evaluated in the participants. A patent application of the developed system was submitted to INIT-UFES. Future studies should consider expanding the possibilities of controlled equipment and devices, as well as the time of use.
