This paper presents the further development and enhancement of an electrically controlled Barony's Chair, developed from the model previously modified by Gessinger (2005), who in turn based developments on the Masters dissertation of Piedade (2001), both having been developmental works carried out in the Microgravity Centre, Pontifical Catholic University of Rio Grande do Sul (PUCRS). Several new items were incorporated: aluminium structure, steel structure, a cover, hydraulic brake, joystick, an application to capture and quantify signs of disorientation, micro-camera, wireless USB HUB, video monitor, USB ports expander, flight simulator software, rotating coaxial connector and device for distribution of electric energy. A theoretical review of the physiology related to spatial disorientation and motion sickness was conducted and revealed details of the origin of this phenomenon and its implications for causing accidents during flights and space missions. This directed the focus of research to enhance the Barany's Chair, a tool used in the training of pilots and astronauts in order that flight safety and prevention of accidents can be improved. The description of each of the components incorporated and its application will be presented, followed by results and discussions regarding the proposed improvements of the MicroG Centre Barony's Chair. It is believed that the enhanced Barany's Chair can have a wide application in the area of aeromedical education and research, which in turn will contribute to the safety of air travels and space missions.
