Visualization of coverage probability for slow walking in the indoor ecological validation.
<p>The black solid line represents speed as measured by the mobile gold standard for slow walking. Green, yellow, red and blue lines in different linestyles represent different speed estimates by different algorithms and models. The filled areas colored from light to dark grey around the black solid line indicate coverage probality levels from 0.1 to 0.3 m/s. Speed intervals are sorted increasingly across all participants for reasons of clarity and readability.</p
Visualization of coverage probability for even faster walking in the indoor ecological validation.
<p>The black solid line represents speed as measured by the mobile gold standard for even faster walking. Green, yellow, red and blue lines in different linestyles represent different speed estimates by different algorithms and models. The filled areas colored from light to dark grey around the black solid line indicate coverage probality levels from 0.1 to 0.3 m/s. Speed intervals are sorted increasingly across all participants for reasons of clarity and readability.</p
Open dialectendata
<p>Individual coverage probability with a maximum difference of 0.1 m/s (CP1) to 0.3 m/s (CP3) as well as concordance correlation coefficient (CCC) including 95% confidence intervals (95% CI) for each algorithm across all speed levels.</p
Step features.
<p>Characteristics calculated for each detected step consisting of values . Each of the features listed above (except for the step duration) was computed for each axis , , as well as for the energy derived from the actibelt® signal which results in a total of 41 features. The columns three to six indicate which features and axes were used for the respective models.</p
Visualization of coverage probability for participant 02 (female, 23 years) in the experiment for outdoor ecological validity.
<p>The black solid line represents speed as measured by the mobile gold standard for running. Green, yellow, red and blue lines in different linestyles represent different speed estimates by different algorithms and models. The filled areas colored from light to dark grey around the black solid line indicate coverage probality levels from 0.1 to 0.3 m/s.</p
