This paper presents user assessment results of perceived psychometric characteristics for a body-machine interface (BMI) designed to control a 6-degree of freedom robotic arm, developed by our research team. The BMI was designed to be wearable, immersive and intuitive, constituting the first part of a hybrid real-time user interface. A total of 34 volunteers participated in this study, performing two sets of three tasks in which they controlled the robotic arm, a) within direct line of sight and b) through a video link. All participants completed the “GODSPEED” questionnaire before and after the performing of the tasks. Men and engineers assigned lower values on average for all characteristics included in the “GODSPEED” questionnaire. The complete MERCURY prototype system is still under development and is additionally comprised of a wearable brain-computer interface (BCI) headset. The complete hybrid-interface system is primarily intended for research into human-computer interfaces, neuro-physiological experiment that will lead to the development of a robotic interface for rehabilitation.
