During short-term wakefulness trials, participants wore the sensor-integrated sleep pants and assumed four predefined postures (supine, prone, left lateral, and right lateral), yielding 202 annotated posture instances. A confusion matrix was employed to derive sensitivity, specificity, and overall accuracy. Overnight monitoring involved concurrent data acquisition from the sensorized sleep pants and an infrared camera. Statistical analyses included paired t-tests or Mann\u2013Whitney U tests to examine inter-method differences, Bland\u2013Altman plots for agreement assessment, and scatter plots to quantify linear correlations. User feedback on comfort and impact on sleep was collected via questionnaire.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In awake trials, the system achieved 96% overall accuracy, with mean sensitivity and specificity of 0.95 (0.93\u20130.98) and 0.98 (0.97\u20130.99), respectively. Overnight data revealed no statistically significant differences between the two monitoring methods across all postures.
