IMU-WPS hybrid position estimation test-bed development

Lately, a range of applications of the LBS(Location Based Service) is being extended to indoor position estimation. This investment is caused by a huge expectation about the bright prospect of indoor LBS market, including mobile advertisement. Indoor position estimation is now being studied with various methods. Among them, the central field of indoor estimation method by using smart-mobile sensors. However, this method has its limitation within an urban environment because of sensing obstructions. To overcome the limitation of the IMU-based method, we determined the need of a combination of the IMU-based method, an infra-based estimation method and a hybrid design. So, we will use hybrid IMU-based method and a wireless infra method.(WPS).
