dc.description.abstract | In this paper we present a PDR (Pedestrian Dead
Reckoning) system with a walking status awareness algorithm. PDR is a device which provides position information of the pedestrian. In general, the step length is estimated using a linear combination of the walking frequency and the acceleration variance for the mobile phone. It means that the step length estimation accuracy is affected by coefficients of the walking frequency and the acceleration variance which are called step length estimation parameters. Developed PDR is assumed that it is embedded in the mobile phone. Thus, we used a single sensor module which is attached to a waist and a pants pocket of a pedestrian. A single sensor module consists of three axis accelerometers, a micro processor and Bluetooth. The step length estimation parameters can be different from each phone location and pedestrian`s step motion such as walk or run. It means that different parameters can degrade the accuracy of the step length estimation. Step length estimation result can be improved when appropriate parameters which are determined by pedestrian walking status awareness algorithm. In this paper, the pedestrian walking status awareness algorithm for PDR is proposed. | en |
