This study evaluated whether two people with multiple disabilities and minimal motor behavior would be able to improve their Drag-and-Drop (DnD) performance using their finger/thumb poke ability with a mouse scroll wheel through a Dynamic Drag-and-Drop Assistive Program (DDnDAP). A multiple probe design across participants was used in this study…

This study evaluated whether two people with multiple disabilities who could not easily use a computer through a standard input device (i.e., mouse or trackball) would be able to improve their pointing performance using thumb poke with a standard trackball through a Dynamic Trackball-Pointing Assistive Program (DTPAP) and a newly developed…

This study evaluated whether two people with multiple disabilities would be able to improve their pointing performance through an Automatic Target Acquisition Program (ATAP) and a newly developed mouse driver (i.e. a new mouse driver replaces standard mouse driver, and is able to monitor mouse movement and intercept click action). Initially, both…

This study assessed whether two people with profound multiple disabilities and minimal motor behavior would be able to control environmental stimulation using thumb poke ability with a mouse wheel and a newly developed mouse driver (i.e., a new mouse driver replacing standard mouse driver, and turning a mouse into a precise thumb poke detector).…

This study evaluated whether two people with multiple disabilities and minimal motor behavior would be able to improve their pointing performance using finger poke ability with a mouse wheel through a Dynamic Pointing Assistive Program (DPAP) and a newly developed mouse driver (i.e., a new mouse driver replaces standard mouse driver, changes a…

A computerized symbol processor system using an Apple IIe computer and a Power Pad graphics tablet was tested with 22 nonspeaking, multiply disabled students. The students were taught to express themselves independently in writing, and they did significantly better than control students on measures of language comprehension and symbol recognition.…

An augmentative and alternative communication device was designed for a nonspeaking, blind, severely mentally retarded 11-year-old. The device consisted of a computer-supported expanded keyboard that produced synthetic speech output when tactile symbols were activated. Described are the assessment procedures, instructional procedures, and…
