With the development of the ubiquitous pedestrian position in environments where global navigation satellite system is unavailable or there is no preinstalled wireless device for positioning, the use of self-contained sensors becomes more important. Thus, this paper proposed a 3-D pedestrian position system combined with commercial microelectromechanical systems microinertial measurement unit (MIMU) and surface electromyography (SEMG) sensor. The signal of the SEMG is used mainly in two aspects: 1) to improve the recognition rate of motion pattern and 2) to obtain the more accurate 3-D velocity contrasted to MIMU. Therefore, satisfied 3-D position accuracy is obtained in two different terrain environments.
