Silver 1 Daniel Silver Ms. Cates English 101 22 May 2008 Computing Options for Physically Challenged Users The ever-increasing presence of computers in everyone’s lives has generated an awareness of the need to address computing requirements for those who have or may develop physical limitations CITATION Har \p 93-95 \n \l 1033 . For these users, several different types of input and output methods can make their interactions with computers easier, more productive, and less frustrating. Various input devices are available for users with motor disabilities(Harkin, 2008, pp. 34-75). A keyguard is a metal or plastic plate placed over the keyboard that allows users to rest their hands on the keyboard without accidentally pressing any keys. Small trackballs that the user controls with a thumb or one finger can be attached to a table, mounted to a wheelchair, or held in the user’s hand. Another option for people with limited hand movement is a head-mounted pointer. To simulate the functions of a mouse button, a user works with a foot pedal, hand pad, or pneumatic instrument controlled by puffs of air.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
