What transition defines the current state of the art in posture monitoring development compared to initial stages?

The focus has moved from asking *Can we measure it?* to asking *How accurately and unobtrusively can we correct it in the real world?*

The historical progression of posture monitoring technology demonstrates a clear maturation curve. In the earlier phases, the fundamental challenge was technological feasibility: developing sensors and hardware robust enough to reliably capture body kinematics outside a laboratory setting. The current focus, reflecting the successful integration of MEMS technology and refined algorithms, is no longer centered on the basic ability to measure deviations. Instead, development is highly oriented toward practical, real-world implementation challenges—namely, refining the precision and subtlety of the corrective measures (the feedback protocol) so that they are effective trainers rather than annoying distractions for the end-user.
