The Design of Worker's Behavior Analysis Method in Workplace Using Indoor Positioning Technology

Abstract

ABSTRACT:This study presents a method for analyzing workers' behavior using indoor positioning technology and field test in the workplace. Recently, various indoor positioning methods, such as Wi-Fi, Bluetooth low energy (BLE), visible light communication, Japan's indoor messaging system, ultra-wide band (UWB), and pedestrian dead reckoning (PDR), have been investigated. The development of these technologies allows tracking of movement of both people and/or goods in indoor spaces, people and/or goods behavior analysis is expected as one of the key technologies for operation optimization. However, when we use these technologies for human tracking, there are some problem as follows. 1) Many cases need to use dedicated facilities (e.g. UWB). 2) When we use smartphone as sensing device, battery depletion is one of the big problem (especially using PDR). 3) the accuracy is instability for tracking (e.g. Wi-Fi). Based on these matters, in this study we designed and developed an indoor positioning system using BLE positioning. And, we adopted smartphone for business use as sensing device, developed a smartphone application runs on android OS. Moreover, we conducted the field test of developed system at Itoki Corporation's ITOKI Tokyo Innovation Center, SYNQA, office (Tokyo, Japan). Over 40 workers participated in this field test, and worker tracking log data were collected for 6 weeks. We analyzed the characteristics of the workers' behavior using this log data as a prototyping.

Process Optimization Method for the Simplification of Developing Indoor Positioning Environment

“…This type estimates the selfposition using the signal strength from installed sensor devices and its position information in advance. 10,11) Especially, since iBeacon has appeared, indoor positioning using BLE is starting to be used more frequently because the device can be purchased at a low cost and has a low constraint during installation. 12) On the other hand, positioning methods such as Fingerprinting, PDR, SLAM, etc.…”
