Biomechanical outcomes from the MoCap and HL2 systems for continuous walking task.
| MoCap Mean (SD) | HoloLens 2 Mean (SD) | Bias (95% CI) | ICC (95% CI) | |
|---|---|---|---|---|
| Cumulative distance (m) | 46.95 (7.15) | 47.46 (7.26) | 0.51 (0.38, 0.64) * | 0.99(0.99, 0.99) |
| Number of steps (count) | 51.39 (5.70) | 51.53 (5.61) | 0.14 (−0.04, 0.32) * | 0.99(0.99, 1.00) |
| Step length (m) | 0.64 (0.06) | 0.66 (0.06) | 0.02 (0.02, 0.02) * | 0.99(0.99, 1.00) |
| Stride length (m) | 1.31 (0.12) | 1.35 (0.12) | 0.04 (0.03, 0.04) * | 0.98(0.97, 0.99) |
| Total walking time (s) | 29.74 (1.75) | 29.72 (1.74) | −0.02 (−0.03, 0) * | 0.99(0.99, 0.99) |
| Gait velocity (m/s) | 1.59 (0.23) | 1.61 (0.24) | 0.02 (0.02, 0.03) * | 0.99(0.99, 0.99) |
* = TOST p-Value < 0.05; bias is defined as (HL2 measure–MoCap measure).
