DEVELOPMENTS and THRUSTS by YEAR

First generation computer-based Human Performance Measurement System (HPMS) was completed and evaluated (at this time, it's focus of measurement was characterized as "neurologic function").

Center for Advanced Rehabilitation Engineering formed (sponsored by the National Institute on Disability and Rehabilitation Research as a Rehabilitation Engineering Center, with research emphasizing "improved measurement of performance").
Characterization of the focus of measurement shifted: "neurologic function" to "sensorimotor function".

Second generation of the Human Performance Measurement System was developed (more generalized architecture, increased breadth of measurement capability).
Characterization of the focus of measurement continues to shift: "sensorimotor function" to "sensorimotor performance" (note: "characterization" shifts, not "focus").

Technology transfer via exclusive license by UT Board of Regents to Human Performance Measurement, Inc for human performance measurement technology.
More fundamental conceptual issues begin to emerge and capture attention (what to measure, hierarchical relationships of measures, prediction in broader contexts from lab-based measurements, inconsistencies in fields, etc.)
Identification of "fundamental problems" and modeling efforts begin.
Characterization of focus of measurement shifts once more: "sensorimotor performance" to "human performance" - recognized to encompass life sustaining, sensory, motor, and cognitive domains.

The basic set of constructs for what was later dubbed General Systems Performance Theory (GSPT) was introduced in the context of human system performance and in association with the introduction of the Elemental Resource Model (ERM).

Recharacterization of "basic problems of interest" from mostly rehabilitation focus (i.e., individuals with disability and their attempts to accomplish tasks) to any human attempting any task. Solve key problems in rehab.. solve same key problems in other application areas ... or vice-versa.
Initial experimental work conducted with human data on basic concepts of GSPT/ERM.
Process now dubbed "Nonlinear Causual Resource Analysis" introduced.

As part of the HPOSS effort, utility and performance requirements identified and first generation design developed for "Single Point 3 Dimensional Digitizer" instrument.

First generation Human Postion and Orientation Sensing System design (wireless, inertial, and magnetic field based) was identified and plans were initiated to pursue as a generic architecture for human performance measurement, task analysis, and virtual reality applications.
