Abstract: An alignment system that monitors posture and provides alignment feedback about the monitored posture to an individual is described. This alignment system may include an alignment device that is worn or remateably attached to the body of the individual, e.g., in or near a midline (such as at or near a midpoint between the Iliac Fossa) of the posterior lumbar or sacral region. The alignment device may include one or more alignment sensors and/or may communicate with one or more separate alignment sensors that monitor the alignment of the individual's pelvis. This alignment data may be analyzed by the alignment device or another electronic device (such as an application executed on the other electronic device and/or a remotely located computer). Then, based at least in part on the analysis, the alignment device may selectively provide the alignment feedback to the individual (e.g., when misalignment is detected or determined).
