A Study on Indoor Presence Management System Using Smartphone

摘要

The aim of this paper is to perform indoor presence management using smartphone. Our proposed method estimates user position and state by smart-phone sensors. The position information is estimated by accelerometer and direction sensor. The state information is estimated using gravitational acceleration can be acquired by accelerometer. By using this system, it can estimate human position within 100 cm errors. In addition, this system can estimate the state of subject in 99.2 % accuracy.
