(a) XSENSOR insole showing location of placement of cylinders for regional assessment (dashed lines). (b) Average peak pressure maps for difference from target pressures for whole insole protocol. (c) Regional protocol, with cylinder area overlay (dashed lines) sensor size has been scaled to correct for differences between XSENSOR insole sizes.
Fig 2.
Contact area for each insole and cylinder size for day two across the 2s trial.
Error bars denote standard deviation across three trials.
Fig 3.
Peak and mean pressure values recorded over 0, 2, 10 and 30 s for the 7 target pressures for both insoles on day one.
Where circles mark the mean pressure data, error bars denote the Root Mean Square Error (RMSE) across all individual sensels about the mean recorded value and the triangle marks the peak pressure data.

Peak pressure values recorded at 2s for the 7 target pressures in both insoles between days.
(a) Proximity of measured values to the target (dashed line). (b) Relation between measured peak pressure on Day 1 and Day 2 showing slope of curve. (c) Average absolute difference (error) between days plotted against between day mean values (d) Average difference between days as percentage of target against between day mean values.
