Three types of rapid message composition for non-speaking persons, classified according to keyboard, are described: sequential keyboard, "semantic" input through iconic representation, and chord keyboard. The strengths, drawbacks, and potential of each type are discussed for a user population with good keying ability and normal cognitive and…

This booklet provides information about access to computers through alternate keyboards used by students who have physical impairments. Part 1 describes a typical technology team and the alternate keyboard selection process. Part 2 discusses the practical aspects of everyday teaching and living with an alternate keyboard user and includes…

Forty developmentally delayed and 40 non-delayed kindergarten children completed an alphabet matching task and a spelling task using 2 different computer input devices: a traditional computer keyboard and a touch-sensitive computer screen. The touch-sensitive screen generally improved the performance of both groups. (Author/JDD)

This review examines electronic braille input-output devices which have a braille keyboard for data entry and/or a braille display. Four braille notetakers and two braille computer systems are evaluated, commenting on their keyboards, ease of use, documentation, and analysis of speech and/or the braille display. (JDD)

This paper summarizes selected findings on approaches to increasing the rate of communicatively appropriate responses in augmentative and alternative communication. Six approaches--efficient keyboard layouts, reduced keys keyboards, Minspeak with Words Strategy, enlarged keys keyboards, abbreviation expansion, and lexical prediction--are reviewed…

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)

Reports on a study of the ability of preschoolers and first, second, and third graders to use three computer input devices: a joystick, a mouse, and a keyboard. For all grade levels, the mouse offered the greatest ease of use in manipulating icons, followed by the joystick and the keyboard. No effect for gender was found. (Contains 30 references.)…

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…

The Media and Technology section of this collection of conference presentations contains the following 10 papers: "Carpooling on the Information Superhighway" (Lorna Veraldi); "New Media Departure in 'The Principle of Relative Constancy': VCRs" (Ghee-Young Noh); "Why the Western Design Approach Does Not Work for Asian…

This continuation of an earlier article that described computer-based speech recognition products focuses on future hardware and software predictions. Highlights include effects that speech input/output could have on teaching language arts in elementary and secondary schools; changes in thought processing factors; use by the physically…

Severely physically disabled children may need special communication techniques or aids to help them in conversation/interaction and writing. An individual with speech problems may need an augmentative communication system, and selection of the right system, whether non-electronic or electronic, can be a complex process. To assist in the task of…
