In order to do so, the characteristics and inconveniences of the vision impaired as passengers and pedestrians were examined and their reactions to warnings and dangerous situations were analyzed. Users’ needs and robots’ functional requirements were applied to analyze the requirements of road guidance system. To verify whether the proposed requirements would be applied to robots effectively, a service scenario was used.
