Counting the steps for a loudness scale

The Journal of the Acoustical Society of America, 2021
It is a century-old desire to construct a scale for loudness. Such a scale’s intervals would, on face value, be just-noticeable changes in loudness. Those changes correspond to empirical just-noticeable-differences (jnds) in RMS sound-pressure-level.

An improved step counting algorithm using classification and double autocorrelation

International Journal of Computer Applications, 2020
The objective of this paper was to develop an end-to-end algorithm that would improve the step counting accuracy in regular walking/running data and also meet the ANSI/CTA-2056 standards.

Evaluating Step Counting Algorithms on Subsecond Wrist-Worn Accelerometry: A Comparison Using Publicly Available Data Sets

Journal for the Measurement of Physical Behaviour
Background: Walking-based metrics, including step count and total time walking, are easily interpretable measures of physical activity. Algorithms can estimate steps from accelerometry, which increasingly is measured with accelerometers located on the ...

Step-Counting Validity of Wrist-Worn Activity Monitors During Activities With Fixed Upper Extremities

, 2020
Little is known about validity of wrist-worn physical activity monitors during activities when an arm-swing is not present. The purpose of this study was to compare the step-counting validity of wrist-worn activity monitors (Fitbit Charge HR Series 2 ...

STEAR: Robust Step Counting from Earables

EarComp@UbiComp, 2019
This paper shows that inertial measurement units (IMUs) inside earphones offer a clear advantage in counting the number of steps a user has walked. While step-count has been extensively studied in the mobile computing community, there is wide consensus ...

Evaluation of Step-Counting Interventions Differing on Intensity Messages.

Journal of Physical Activity and Health, 2019
BACKGROUND Step-counting interventions with discrepant intensity emphases may elicit different effects. METHODS A total of 120 sedentary/low-active, postmenopausal women were randomly assigned to one of the following 3 groups: (1) 10,000 steps per day (

Step Counting Navigation Assistant

2019 1st International Conference on Advanced Technologies in Intelligent Control, Environment, Computing & Communication Engineering (ICATIECE), 2019
Navigation is an emerging field and in the recent past extensive research is being carried out. Navigation can be broadly differentiated into Indoor Navigation and Outdoor Navigation[1]. Outdoor Navigation immediately recollects of the one with GPS which is most popularly used these days.

Accurate position and orientation independent step counting algorithm for smartphones

Journal of Ambient Intelligence and Smart Environments, 2018
Step counting (SC) algorithms can be applied to different areas such as well-being applications, games, and indoor navigation. Many existing SC algorithms for smartphones use data from inertial sensors to infer the number of steps taken, but their ...

Validity and Reliability Evaluation of Four Commercial Activity Trackers' Step Counting Performance

Telemedicine journal and e-health, 2018
Introduction: Activity trackers are useful tools for physical rehabilitation purposes. Most available activity trackers are designed for fitness and wellness use, lacking in both accuracy and precision at lower speeds.
