This research addresses the critical need for improved access to Assistive Technology (AT) for people with disabilities, guided by human rights frameworks and a growing global emphasis on inclusive technology. This research investigates the potential of an AT Passport as a solution for improving access to Assistive Technology. This proposed passport would be a centralised, personalised document outlining an individual’s AT needs, preferences, and recommendations. The research aims to understand existing barriers to AT access, define the potential role of the AT Passport in overcoming these barriers, and develop a framework for its implementation and adoption. To achieve these aims, the research unfolds in four distinct phases, employing a pragmatic, exploratory sequential mixed-methods design to explore the feasibility and impact of an AT Passport. The research commenced with exploring the lived experiences of individuals with disabilities and their access to AT, utilising Interpretative Phenomenological Analysis to uncover existing barriers and understand the potential value of an AT Passport. Informed by these qualitative insights, a quantitative survey was conducted to gather statistically grounded data on AT use patterns and challenges. Concurrently, a Delphi study engaged expert AT user participants to achieve consensus on a core set of functionalities and design features for the AT Passport, ensuring the framework is deeply rooted in lived experiences and user needs. The research culminates in developing a comprehensive and user-centred AT Passport framework by synthesising the qualitative and quantitative findings and incorporating the Delphi consensus on essential functionalities and design features. This framework provides concrete recommendations for designing, developing, and implementing the AT Passport, ensuring its integration within existing support systems and promoting long-term sustainability. An AT Passport is needed to create a more inclusive future for people with disabilities by improving access to assistive technology. While promising, the current AT Passport framework has limitations. Further research is needed to refine the framework and maximise its impact.
