Event Venue Navigation for Visually Impaired People

There is an increasing need for a navigation system that supports visually impaired people walking around an event venue without a human guide helper. Although various methods for indoor navigation systems have been proposed, existing navigation systems have a complicated setup procedure to prepare the environment, making it difficult for event operation staff to deploy the system within a limited time. In this paper, we propose an event venue navigation system for visually impaired people that can be prepared within one hour even if the event staff does not know how to use the system. Our experiment shows that one event staff member can prepare the environment in about 20 minutes and that the system can suppress the user's positioning error within two meters.
