JACK

Overview

JACK is a digital human modelling software — used to create and animate three-dimensional virtual human figur es that simulate how workers of different body sizes interact with workstations, vehicles, machinery, and environments in a virtual environment before physical construction or production begins. JACK incorporates anthropometric databases for multiple popul ations, biomechanical analysis tools including spinal load calculation and strength prediction, and ergonomic assessment modules — allowing ergonomists and design engineers to evaluate reach envelopes, posture, visual fields, and physical demand of propose d designs and identify ergonomic problems at the design stage. JACK is widely used in automotive, aerospace, and manufacturing industries for virtual ergonomics validation.
