资源简介：
<p>The dataset includes kinematics data recorded by a Motion Capture System (Vicon Motion System, Oxford, UK) at 100Hz. Data were filtered (fourth-order zero-lag Butterworth low-pass filter with a cutoff frequency of 6 Hz) and exported with Vicon’s Nexus 2.15 software.</p>
<p><b> 📁 LW_kinematics_data (JSON Dataset) </b></p>
<p>This dataset contains gait cycle data collected across 24 subjects, lateral walking speeds, and directions. The data is stored as a hierarchical JSON file for ease of parsing, analysis, and expansion.</p>
---
<p><b>📐 Structure </b></p>
<p>The data is organized in four hierarchical levels:</p>
<p>Subject ID → Direction → Speed → Cycle Number → Kinematic Variables (markers 3D position)</p>
<p>Where:</p>
<p>- **Subject ID**: A numeric string (e.g., `"7"`),
- **Direction**: `"Left"` or `"Right"`, indicated the direction of lateral movement
- **Speed**: Integer string representing the gait speedin hm/h (e.g., `"18"` means 1.8 km/h). Speed values can be easily converted to m/s by dividing for 36 (e.g. 18/36 = 0.5 m/s).
- **Cycle Number**: A string ID for each gait cycle (e.g., `"1"`, `"26"`, etc.)</p>
<p>Each cycle entry contains a dictionary of 55 sampled variables over time:
Frame is an index var - The following variables are grouped by three, and named as right or left (R, L) + the name of the body marker + the axis (e.g. RLOBx, RLOBy, RLOBz, for a total of 9 anatomical positions and 18 markers).
LOB = Temporal lobe SH = Acromion ELB = Elbow WR = Ulnar stiloyd process GT = Great Trochanter KN = Knee (lateral) AN = Malleolus lateral HEE = Heel MT = 5th Metatarsal
The 3D sapece were calibrated following the right hand rule, with the axis "X" = mediolateral; "Y" = anteroposterior; "Z" = vertical. Values are in mm. </p>
