Observed postural variations across computer workers during a day of sedentary computer work
Bibliographic record
Abstract
Sedentary computer work is widespread and typically occurs at a fixed-height seated workstation. Both neutral and at-risk postural classes of the back and neck were observed among 11computer-intensive workers using such workstations who had reported high discomfort levels. Four video recordings of approximately 1 hour each over the working day were analyzed to determine the percent duration and number of observations of each body and neck posture. Risky slouching (32.3% ±17.3%) and neck forward postures (16.9% ±12.3%) varied significantly by participant but not by time of day. Absence from video field of view of the workstation was not negligible, occurring 23.8%±14.8%. Postural changes of slouch and neck forward occurred several times during each recording (4.8±1.9 and 2.5±0.9, respectively) and varied significantly by participant but not over the day. Despite these postural adjustments, the prevalence of risky postures suggests that static workstations are fundamentally problematic.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
