Study conducted to evaluate a prototype virtual reality electric wheelchair simulator, which was designed at the National Rehabilitation Center for Persons with Disabilities in Japan to assess clients' powered wheelchair operating skills. The system is based on a Stewart Motion Platform, which allows for six degrees of freedom. Two screens are used to display a horizontal view of the screen, and another to display the ground. A seat designed by Invacare and a Suzuki joystick are used, as the wheelchair simulator is compatible with a number of input devices, including standard joysticks, a pad controller, a mini joystick, chin control, and puff control. The study consisted of evaluations conducted by a group who were experienced at using powered wheelchairs, and a group who were not experienced at using powered wheelchairs. Data regarding course performance across subjects was collected with regards to speed, orientation, position, and proper use of control inputs. A qualitative section was also incorporated regarding participant perceptions of the system. The researchers found that the system was effective in distinguishing between participants who were experienced versus participants who were new to using powered wheelchairs. Implications for future research are discussed. This research was conducted at the Rehabilitation Center for Persons with Disabilities in Japan.
