Evaluating gaze-driven power wheelchair with navigation support for persons with disabilities.

Area of Science:

• Rehabilitation Engineering
• Assistive Technology
• Human-Computer Interaction

Background:

• Individuals with severe disabilities often face significant mobility limitations.
• Existing powered wheelchairs may not fully address complex user needs for independence.

Purpose of the Study:

• To evaluate the functionality and safety of a novel gaze-driven powered wheelchair add-on with navigation support.
• To assess the perceived meaningfulness of this system in enhancing user independence and participation.

Main Methods:

• A novel add-on system combining gaze-driven control and navigation support was developed for standard powered wheelchairs.
• The system was customized for three users with severe disabilities based on their individual needs.
• Functionality, safety, and user experience were evaluated in the users' home environments.

Main Results:

• The gaze-driven system demonstrated potential for safe and independent indoor mobility.
• Users reported the system as fun, meaningful, and effective in reducing dependency.
• The system facilitated assessment of user capabilities, aiding personalized rehabilitation.

Conclusions:

• The novel gaze-driven powered wheelchair add-on offers a promising solution for enhancing independent mobility in individuals with severe disabilities.
• This technology can significantly improve quality of life by fostering independence, participation, and psychological well-being.
• The system serves as a valuable tool for rehabilitation and motivating training.
