The key issue in achieving a pedestrian navigation service is to grasp the spatial context of pedestrians, which is mainly characterized by the places of their interest. We have developed a pedestrian navigation system uNavi, based on our proposed infrastructure that is capable of associating information services to the places of human interest. This paper focuses on the implementation and deployment...
After a public experiment of the indoor guidance system using FLC (fluorescent light communication), we found that FLC provides a promising medium for the installation of a guidance system for the visually impaired. However, precise self-positioning was not satisfactorily achieved. In this article, we propose a new self-positioning method, one that uses a combination of RFID (radio-frequency identification),...
While car navigation systems today can meet our daily needs, pedestrian navigation systems available still fall short of practical needs. This is mainly because existing positioning methods such as GPS has limitation in terms of their applicability and accuracy. In this paper, a novel pedestrian navigation approach based on a unique identifier framework is proposed. The approach integrates ubiquitously-deployed...
In this paper, we propose a novel RFID reader/writer architecture that dynamically retargets various protocols of RFID by changing configuration software. The proposed architecture is not software defined radio, but parameterized hardware that is specialized in RFID protocols. This architecture consumes lower power than that of software defined radio, because the proposed architecture does not require...
