Exploring DHHers experience influencing factors in multimedia-based driving training through a service design study

Area of Science:

• Human-Computer Interaction
• Accessibility Studies
• Transportation Research

Background:

• Deaf and hard-of-hearing individuals (DHHers) face significant barriers in obtaining driver's licenses in China.
• Existing driver training services lack accessibility and tailored support for DHHers.
• Limited research addresses the specific challenges and needs of DHHers in driver education.

Purpose of the Study:

• To identify critical factors influencing the driving training experience of DHHers.
• To propose optimization strategies for driver training services using multimedia technology.
• To enhance the quality of life and employment prospects for DHHers through improved driving accessibility.

Main Methods:

• Grounded theory and interviews with 20 DHHers to explore influencing factors.
• Development of a multimedia-integrated driving training service process.
• Simulation experiment with 41 DHHers using questionnaire-based research.
• Bayesian Structural Equation Modeling (BSEM) to validate user experience models.

Main Results:

• Social support, technology support, communication efficiency, training efficiency, environment construction, and emotional support significantly determine the DHHers' driving training experience.
• Personal factors moderate the impact of training efficiency, environment construction, and emotional support on user experience.
• Multimedia technology integration positively influences training efficiency and communication.

Conclusions:

• Optimizing driver training for DHHers requires a holistic approach addressing social, technological, and environmental factors.
• Multimedia technology offers a viable solution for creating more accessible and effective driver education.
• The proposed strategies can improve DHHers' independence, quality of life, and employment opportunities.
