Fuzzy Adjustment Control in Command Evaluation Platform

Area of Science:

• Rehabilitation Engineering
• Human-Computer Interaction
• Assistive Technology

Background:

• Motor handicapped individuals face significant challenges using standard computer interface devices.
• Existing research focuses on developing new hardware or adapting current software for user needs.
• This article explores software adaptation to enhance usability of existing assistive technologies.

Purpose of the Study:

• To analyze the PLatform to Evaluate ICT for Assistance software platform.
• To enhance the use of pointing devices for motor handicapped users through software adaptation.
• To evaluate and improve the adaptation of interface commands for increased user control.

Main Methods:

• Developed a quantitative analysis approach with task and adaptation indicators for occupational therapists.
• Introduced a fuzzy rehabilitation module to adapt user commands without altering interface hardware.
• Tested the system on a 12-year-old quadriplegic boy over two days, with multiple attempts.

Main Results:

• The subject initially struggled to control the joystick without customization.
• With the adapted system, the subject successfully controlled the mouse cursor.
• The customized device significantly improved the user's ability to interact with the computer.

Conclusions:

• The developed adaptation technique enabled effective control of computer pointing devices for the subject.
• The evaluation technique provided crucial parameters for refining the adaptation algorithm.
• Software adaptation offers a viable solution for improving computer accessibility for individuals with motor impairments.
