This thesis explores the development of a product-service system that supports independent mobility for individuals with both visual and mobility impairments (MVIPs). These individuals face unique challenges, as existing mobility aids do not adequately address the combined limitations of impaired vision and restricted physical movement. The project aims to bridge this gap by integrating environmental sensing and tactile feedback technologies into a rollator-based system. The design approach follows a human-centered and iterative process, combining desktop research, stakeholder interviews, user testing, and prototyping.

The final outcome, VAMO, consists of modular components that can be mounted on an existing rollator and paired with a digital interface. The system provides users with real-time spatial awareness via vibration feedback, facilitating safer navigation. The project evaluates the effectiveness of the feedback system through user testing and expert reviews. While the solution is not universally applicable due to user diversity, it demonstrates the potential for inclusive design to improve quality of life and autonomy for MVIPs. The thesis contributes to the field of assistive technology by proposing a scalable and adaptable mobility aid that aligns with current trends in modularity, personalization, and accessibility. ...
