A 30 second game

Your hunch versus the evidence.

Two quick calls on a 12.8 second warehouse clip. Make yours on feel, then see what the GRW engine actually read.

Call 1 of 2 · The lift

Does this lift get flagged?

A 12.8 second stock clip of a worker lifting in a warehouse. GRW Movement watches for lower back strain, among other risks.

  • Flagged
  • No flag
See GRW’s read

Sample
  • 0Strain flags raised
  • 56°Highest trunk lean, under the 60° line
  • 384 of 384Frames with the worker in view
  • 133Frames the lower back check could read

The trunk peaked at 56 degrees, under the 60 degree line where the lower back flag starts, so nothing was flagged.

Sample: a real GRW engine run on licensed stock footage, from the GRW Movement sample report.

Call 2 of 2 · The reach

How many overhead reaches?

Same 12.8 second clip. A reach counts when the arm goes past 95 degrees of shoulder flexion.

  • None
  • One
  • Three or more
See GRW’s read

Sample
  • 1Overhead reach counted
  • 6.2 sWhen it happened

One reach, at 6.2 seconds. Easy to miss when you are watching the lift, not the shoulder.

Sample: the same engine run on the same stock clip.

That’s the game

Gut feel is a start. Evidence is better.

GRW reads composure, presence and clarity from ordinary video, so the big calls about people stop running on hunches alone. Every number above comes from a real GRW engine run on licensed stock footage, the public GRW Movement sample.
