This chapter serves as the cornerstone of the book, focusing on the identification and analysis of user requirements critical for the design of wearable feedback systems and navigation aids. Through a user-centred approach, the chapter delves into the specific needs and preferences of visually impaired individuals as well as those with upper limb amputations. These insights are essential for developing effective and intuitive technological solutions. The findings presented here lay the groundwork for the subsequent development and implementation of wearable haptic feedback devices and indoor navigation systems, detailed in later chapters. By prioritizing user needs from the outset, this chapter aims to ensure that the resulting technologies are not only innovative but also practical and user-friendly, addressing the unique challenges faced by both visually impaired users and amputees.
