Discussion of computer input devices focuses on the keyboard, mouse, and touchscreen. Related research is reviewed concerning user preference and performance; advantages and disadvantages of each device are described; guidelines for selection are discussed; and suggestions for future research are offered.

This final report describes a federally funded project (September 1987-August 1989) which developed the "Trace Transparent Access Module," a device which interfaces with standard computers thus allowing children with physical disabilities to participate fully with nondisabled children in classrooms. The module is a small, microprocessor…

Information systems in public places such as community centers and libraries require some means to provide access to individuals with physical, visual, and, if sound is involved, hearing impairments. This paper proposes a seamless adaptable human interface protocol that would allow users to incrementally modify the command and presentation aspects…

This paper reports on a research and development program which developed a more effective interface between personal computer (PC) users with disabilities and computer systems. The program emulates a PC keyboard, enabling disabled PC users to access standard software via a binary (switch) control element. (Author/DB)

Using manual, hardware, and software adaptations, teachers are able to use computer-based educational programing with learning-disabled students who have physical handicaps. This paper describes such technology as keyguards, alternative keyboards, scanning systems, switches, and spelling and grammar checkers. (JDD)

The versatility of the computer can be expanded considerably for young handicapped children by using input devices other than the typewriter-style keyboard. Input devices appropriate for young children can be classified into four categories: alternative keyboards, contact switches, speech input devices, and cursor control devices. Described are…

Three conference papers on rehabilitation technology, authored by staff members of the Trace Research and Development Center, form this collection. The first, "Keyboard Equivalent for Mouse Input" by Charles Lee and Gregg Vanderheiden, describes implementation of a keyboard mouse input device using the numeric keypad. The paper discusses…
