Step detection and step length estimation techniques include detecting salient points in sensor data of one or more sensors. A step frequency is estimated based on a time interval between the detected salient points. A step length of the step may then be computed based on a nonlinear combination...
The context classification accuracy is over 97%, and the root of mean square error (RMSE) of step length estimation is under 8.3% which is a better result than the conventional algorithm.doi:10.1007/s12555-019-0725-xDaehyun KimDepartment of Mechanical and Aerospace Engineering/Automation and ...

Currently, most of Pedestrian Dead Reckoning( PDR) indoor navigation system based on Micro- Mechanical Systems( MEMS) are faced with the problem of estimation step, a nonlinear step length estimation method based on fuzzy logic is proposed.First, this paper chooses a nonlinear step estimation model...
Younger participants underestimated their preferred step length. Overall, the estimates were more accurate for the largest steps than for the preferred-length steps. Conclusion : Step length estimation revealed powerful evidence for overestimation in older adults. Those who overestimated step length ...
A comparison between different step length estimation algorithms for pedestrian dead reckoning is presented. This work covers theoretic evaluation of the estimators' performance and presents a comparison based on measurement data. Measurement data were taken from a group of five adults walking at three ...
Walking status estimation in a portable terminal includes a method for estimating walking status. The method includes setting an observation using an estimated temporary step length, an acceleration variance, and a step frequency. The method also includes generating an observed probability vector comprisin...
strategies on the ridge has focused either on the parabolic case or on simple one-parent strategies without step length adaptation. This paper extends that research by studying the performance of multirecombination evolution strategies with cumulative step length adaptation for a wide range of ridge ...

We hypothesized that split-belt walking with the legs moving at different speeds changes the estimation of the legs' position when taking a step. Thus, we assessed young subjects' perception of step length (i.e., inter-feet distance at foot landing) when they moved their legs (active ...
