Automatic Adjustment of Keyboard Settings Can Enhance Typing

Area of Science:

• Human-Computer Interaction
• Assistive Technology
• Software Engineering

Background:

• Individuals with physical impairments often face challenges with standard computer keyboard settings.
• Optimizing keyboard configurations can enhance typing productivity and user comfort.

Purpose of the Study:

• To develop and evaluate AutoIDA, a software tool for automatic configuration of Windows keyboard settings.
• To assess the impact of AutoIDA-recommended settings on typing performance for individuals with upper extremity impairments.

Main Methods:

• Developed AutoIDA software to monitor user activity and recommend Sticky Keys and key repeat settings.
• Conducted an evaluation study with 14 participants with upper extremity impairments.
• Analyzed changes in typing speed, error rates, and specific key entry efficiency.

Main Results:

• AutoIDA recommended setting adjustments for 10 out of 14 participants.
• Average typing errors decreased from 17.6% to 13.3% with recommended settings.
• AutoIDA prevented approximately 90% of inadvertent key repeats and improved modified character entry.

Conclusions:

• AutoIDA shows potential for improving typing accuracy and efficiency for users with physical impairments.
• Participants found the software useful, indicating a need for such assistive tools.
• Further research may be needed to achieve statistically significant improvements in typing speed.
