How did the system described in the 2009 patent filing advance beyond earlier binary detection methods?
By describing a method for determining the relative angles of various body segments, moving toward understanding the whole posture.
The patent filing from 2009 marked an evolutionary step in posture detection precision. Earlier systems often relied on a relatively crude binary assessment: whether the spine was sufficiently slumped or not, often based on a single point of contact or simple tilt. The 2009 concept represented a significant conceptual leap by detailing a method to calculate the relative angles across multiple body segments. This indicated a shift in focus toward understanding the overall geometry and alignment of the entire posture simultaneously, rather than just triggering an alert based on one specific deviation, demanding a higher level of required precision in measurement.
