Passage: Specialist joysticks, classed as an assistive technology pointing device, are used to replace the computer mouse for people with fairly severe physical disabilities. Rather than controlling games, these joysticks control the pointer. They are often useful to people with athetoid conditions, such as cerebral palsy, who find them easier to grasp than a standard mouse. Miniature joysticks are available for people with conditions involving muscular weakness such as muscular dystrophy or motor neurone disease as well. They are also used on electric powered wheelchairs for control since they are simple and effective to use as a control method.
