Towards a situation awareness design to improve visually impaired orientation in unfamiliar buildings: Requirements elicitation study

Requirements elicitation can be a challenging process in many systems. This challenge can be greater with a non-standard user population, such as visually impaired users. In this work, we report our experience and results of eliciting user requirements for a situation awareness indoor orientation system dedicated to the visually impaired. We elicited our initial system requirements through three different studies that focus on users along with orientation and mobility instructors. Also, we performed a knowledge elicitation through our studies to formulate our system's situation awareness requirements.
