The Implementation and Validation of a Virtual Environment for Training Powered Wheelchair Manoeuvres

Area of Science:

• Rehabilitation Engineering
• Human-Computer Interaction
• Virtual Reality Applications

Background:

• Learning to navigate powered wheelchairs is challenging for new users, especially those with disabilities.
• Traditional training methods require significant practice and carry real-world risks.
• Virtual environments offer a potential solution for safe and effective wheelchair navigation training.

Purpose of the Study:

• To develop and validate a cost-effective virtual reality (VR) application for powered wheelchair navigation training.
• To assess the efficacy of the VR system in improving wheelchair driving skills.
• To explore the potential of VR for accessible and safe rehabilitation.

Main Methods:

• Development of a VR application utilizing consumer-level hardware, deployable in various settings.
• Review of existing virtual environment technologies for training tasks, focusing on wheelchair simulation.
• Conducting a validation study with 33 able-bodied volunteers to assess driving skill improvement.

Main Results:

• The VR system demonstrated a statistically significant improvement in wheelchair driving skills (p < 0.05).
• The application is cost-effective and does not require specialized high-end virtual environment hardware.
• Cybersickness was identified as a notable issue requiring further attention and mitigation strategies.

Conclusions:

• The developed VR system offers a promising, safe, and effective method for training powered wheelchair users.
• This technology has the potential to enhance user competency and independence in mobility.
• Future work should focus on addressing and minimizing cybersickness to optimize user experience and training outcomes.
