Analysis on effect of emitting method of acrostic signals on emitting sequence recognition

Abstract

It is difficult to find an appropriate evacuation route in complicated buildings and underground malls. Therefore, evacuation guidance systems using sound and light has been proposed. The method of the emitting sound was proposed as one of them. In this evacuation guiding method, several influential factors such as speaker setting configurations and sound emitting methods affect the recognition of the emitting direction of sound. In this paper, we discuss the sound emitting configuration to improve the performance of the sound direction recognition through the experiments changing the emitting configurations of audio speaker distance and emitting time interval.
