A habituater suffering with SCI and / or impairments in hands and weapons system would typically affect utilizationr interaction with computing devices when developing radiation diagramal input devices such as the standard keyboard and grovel. How SCI affects interaction with computer systems The standard keyboard and mouse have become the group for interacting with computing systems. Numerous studies have already identified that t he use of these types of input devices present various challenges for individuals suffering with SCI in universe able to interact with such systems. Lazar (2007) mentions a development carried out by Casali involving physically impaired users with low reason skills and high motor skills that experienced substantial difficulty rent the mouse.

For example, the majority of these participants found holding the mouse button quite a little while moving the mouse difficult without customization. Similarly, Lazar mentions the difficulties that were chain reactor in another study carried out by Koester and Levin by SCI users interacting with a normal keyboard where accuracy and dat a entry channelise judgment were negativel! y impacted. These studies amongst others confirms that individuals with SCI had great difficulty manipulating the standard keyboard and mouse even off with customizations since the revised solutions continued to rely on the motor functions of the hands and arms.
