Why computer speed matters for accessibility
For people with motor disabilities including Parkinson's disease, cerebral palsy, multiple sclerosis, and tremor conditions, standard computer interfaces can move too fast to interact with comfortably. Menus close before they can be selected. Double-click windows are too short. Drag operations are difficult to complete.
Slowing down the CPU reduces the speed at which the entire system responds, giving users more time to interact with every element. This is particularly useful for applications that do not have their own speed settings.
CPUKiller has been cited by the Center for Disability Rights, the North Western Melbourne Primary Health Network, and the Victorian Government's accessibility pages as a recommended tool for this purpose.
