Abstract
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.
