Personalize Wayfinding Information for Fire Responders based on Virtual Reality Training Data

Abstract

Modern buildings with increasing complexity (e.g., more square feet, complicated indoor routes) can cause serious difficulties for first responders in emergency wayfinding. While real-time data collection and information analytics become easier in indoor wayfinding, a new challenge has arisen: cognitive overload due to information redundancy. Standardized and universal spatial information systems are still widely used, ignoring first responders' individual difference in information intake. This paper proposes the theoretical framework of a spatial information systems for first responders, which reflects their individual difference in information preference and helps reduce the cognitive load in line of duty. The proposed method includes the use of Virtual Reality (VR) to simulate real world buildings, and the modeling of first responders' reactions to different information formats and contents in simulated wayfinding tasks. This work is expected to set a foundation of future spatial information system that correctly and effectively responds to first responders' needs.
