studyDescription: This dataset consists of time-synchronized raw smartphone IMU, reference (ground truth) IMU, and pressure-sensing walkway data collected from healthy participants as they walked in straight-line and curved trajectories with two different smartphones placed at varying positions and orientations on the body. These data can be used to evaluate factors that impact precision and accuracy of gait metrics derived from smartphones.
