Improvement of indoor position estimation of open-campus event system using ble beacon

Abstract

At the Nagoya Institute of Technology, the “MMDAgent” voice interaction toolkit has been developed for voice-based interactive communication between a system and user. Moreover, based on this spoken dialogue method, an interactive open-campus event system has been developed. This system supports campus visits using MMDAgent, which runs on a smartphone. Existing systems entail some problems related to the accuracy of indoor position estimation. As described herein, we propose an advanced system to improve indoor position estimation using a Bluetooth Low Energy (BLE) beacon. Moreover, we show the effectiveness of proposed system thorough experiment.
