This book provides a comprehensive overview of Inclusive Design as a framework for developing products, services, environments, and learning experiences that enable the diversity and differing abilities of human populations. It examines the influence of international legislation, standards, and policies on accessibility practices and offers practical guidance for effectively integrating inclusion in higher education, research, and business contexts. Readers will find strategies for equitable teaching and assessment, participatory and mixed-method research involving people with disabilities and older adults, and frameworks for embedding Inclusive Design into organizational models, including an adaptation of the Business Model Canvas. Case studies and practical exercises illustrate implementation challenges and opportunities, with attention to emerging technologies such as AI and XR. Emphasizing collaboration, equity, and innovation as drivers of social and economic value, the book will be of interest to researchers, educators, and business leaders seeking evidence-based strategies for inclusive practice.
