Development of an integrated wheelchair tray system for augmentative communication

Area of Science:

• Rehabilitation Engineering
• Assistive Technology
• Human-Computer Interaction

Background:

• Individuals with physical disabilities often require specialized equipment to facilitate communication and daily tasks.
• Existing wheelchair tray systems may lack features crucial for users of augmentative communication systems and powered wheelchairs.
• The integration of communication devices and wheelchair controls onto a functional tray is a significant challenge.

Purpose of the Study:

• To develop and evaluate a novel wheelchair tray system designed for users with physical disabilities who rely on augmentative communication.
• To incorporate features such as anterior/posterior tilt, stowage, and accommodation for communication systems and powered wheelchair controls.
• To assess the technical performance and user acceptance of the prototype system.

Main Methods:

• Development of a prototype wheelchair tray system with specific functional features.
• Field trials involving seven subjects over a 6-week period.
• Performance assessment through caregiver questionnaires and technical monitoring.

Main Results:

• The prototype wheelchair tray system was favorably received by six out of seven participants.
• Caregiver feedback indicated positive reception of the system's functionality and design.
• Technical performance monitoring provided data for further system refinement.

Conclusions:

• The developed wheelchair tray system demonstrates potential for enhancing the independence and usability for individuals with physical disabilities.
• Further design modifications based on user feedback and technical data are recommended to improve consumer acceptance.
• This assistive device addresses key challenges in integrating communication and mobility aids for enhanced user experience.
