Design flexibility in seamless coded pattern for localization

ABSTRACT

Recent development in mobile and ubiquitous computing technology with broadband wireless network has realizing the location based application for mobile and wearable computers. According to the wide spreading number of cellular phone with GPS receiver, it has become easy to provide location based application in outdoor scene. On the contrary, there are several positioning technologies for indoor scene, such using wireless sensors or image processing technology. However, those technologies are still not utilized in daily environment due to the cost inefficiency and the complexity in system setup. Considering the problems in previous positioning system, it is necessary to overcome the following four features to utilize the system in daily scene.

• The system is reasonable and easy to setup.

• The visual feature of the system must not ruin the design of daily environment.

• The system is capable of locating all the users inside the covered environment.

• The system is able to extend in wide area such as public space in buildings.
