Extended Automatic Pointing Assistive Program--a pointing assistance program to help people with developmental disabilities improve their pointing efficiency.

The latest research adopted software technology to improve pointing performance is through an Automatic Pointing Assistive Program (APAP). However, APAP has some limitations. This study evaluated whether two children with developmental disabilities would be able to improve their pointing performance through an Extended Automatic Pointing Assistive Program (EAPAP), which solves the limitations of APAP. Initially, both participants had their baseline sessions. Then intervention started with the first participant. When her performance was consolidated, new baseline and intervention occurred with the second participant. Finally, both participants were exposed to the maintenance phase, in which their pointing performance improved significantly. Data indicated that both participants improved their pointing efficiency with the use of EAPAP and remained highly successful through the maintenance phase. Results of this study showed that, with the assistance of EAPAP, participants can position targets quickly, easily and accurately, thus helping the disabled to solve their pointing problems.

Assisting people with multiple disabilities and minimal motor behavior to control environmental stimulation through a mouse wheel.

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). The study was carried out according to an ABAB design and included a 2-month post-intervention check. The two people increased significantly in the target response (thumb poke) to activate the control system to produce environmental stimulation during the B (intervention) phases. This performance was maintained at the post-intervention check. Practical and developmental implications of the findings were discussed.
