There are likely a quarter of a million individuals who cannot use power wheelchairs because of an inability to use control interfaces. There are likely even more who desire computer access and whose impairments preclude them from being effective users. Historically, isometric controls were thought to have limited application for individuals with movement disorders due to their sensitivity to unintentional movements. The work in this thesis is a series of studies that demonstrate the potential of an alternative method of control—isometric technology. Our work shows that individuals with upper limb impairments can perform just as well with isometric controls as with conventional proportional control, and in some cases individuals with tremor actually perform better with isometric controls. We also introduce work on adaptive control algorithms that can correct errors in movement made with control interfaces and improve performance.
