本篇論文提出一個方法,利用現有的主動式RFID設備,實作出可以在多樓層中進行無縫切換的相關定位系統。本篇論文並沒有使用複雜的三維定位技術進行研究,我們是利用現有的二維定位技術和相關硬體實作出不同樓層之間無縫切換系統的定位。我們在校園內的多樓層之間進行這項實作,切換的準則是依靠樓梯間所擺放的RFID reader接收到的信號強度值(RSSI)作為切換的依據。本論文研究的方向、目的和其他研究不同處在於,我們的重點是著重於不同樓層之間無縫切換技術,而目前還未有類似技術。我們相信這項研發可以提升相關追蹤定位系統的使用者體驗,並促進以RFID為基礎的個人導航系統之普及性。 In this research, an active RFID-based personal navigation system for multi-story indoor environments is proposed. Without using complicated three-dimensional positioning algorithms, we employ an existing two-dimensional positioning engine and equip the system with the capability of seamless positioning handoffs between different floors. The handoff process is triggered by monitoring the received signal strength indicator (RSSI) value observed by the RFID reader deployed in the stairway. The usefulness of the proposed system is verified by conducting an experiment in a campus building. What distinguishes our work from other related works is that we focus on the capability of seamless positioning handoffs between floors, whereas none in the literature mentioned this feature, which we regard as a key to improve user experiences.
