Assisting people with multiple disabilities to improve computer typing efficiency through a mouse wheel and on-screen...

Area of Science:

• Assistive Technology
• Human-Computer Interaction
• Disability Studies

Background:

• Students with multiple disabilities often face challenges with traditional typing methods.
• Developing accessible and efficient computer input solutions is crucial for educational and daily tasks.

Purpose of the Study:

• To evaluate the effectiveness of the Dynamic Typing Assistive Program (DTAP) combined with the On-Screen Keyboard (OSK) for improving typing performance.
• To determine if students with multiple disabilities can enhance their keyboard typing efficiency using a mouse scroll wheel interface.

Main Methods:

• A multiple baseline design across three participants with multiple disabilities was employed.
• Participants utilized the DTAP software, which interfaces with the OSK via mouse scroll wheel input.
• Typing performance was measured before, during, and after the intervention phase.

Main Results:

• All participants demonstrated a significant increase in typing efficiency during the intervention phase.
• The improved typing performance was sustained during the subsequent maintenance phase.
• The DTAP and OSK combination proved effective for enhancing typing speed and accuracy.

Conclusions:

• The Dynamic Typing Assistive Program (DTAP) offers a viable solution for improving computer accessibility for individuals with multiple disabilities.
• Poking the mouse scroll wheel with DTAP and OSK is an effective strategy for enhancing keyboard typing performance.
• Further research should explore the broader applicability and long-term benefits of this assistive technology.
