In this study, we compared an MSJ, IJ, and IJ with the WFLC filter in individuals performing a virtual driving task. The Weighted-Frequency Fourier Linear Combiner (WFLC) filter has been used to cancel tremor effectively in microsurgery. We developed an isometric joystick (IJ) that has performed as well as a conventional MSJ when used by persons with upper-limb impairments in real and virtual wheelchair driving tasks. 1Department of Physical Medicine and Rehabilitation (PM&R), University of Pittsburgh Medical Center, Pittsburgh, PA 2Human Engineering Research Laboratories, Department of Veterans Affairs Pittsburgh Healthcare System, Pittsburgh, PA 3Department of Rehabilitation Science and Technology, University of Pittsburgh, Pittsburgh, PA 4Department of Biomedical Engineering, University of Virginia, Charlottesville, VA 5Department of Orthopedics and Rehabilitation, PM&R Service, Walter Reed Army Medical Center, Washington, DCĪbstract - People with disabilities such as multiple sclerosis and Parkinson's disease have difficulty operating conventional movement-sensing joysticks (MSJs) because of varying levels of tremor.
