Ergonomics & Human Factors

The science of fitting work to people — NIOSH lifting equation analysis, thermal comfort modeling, visual ergonomics optimization, repetitive strain risk assessment, and workstation design principles for human performance and safety.

Ergonomics applies scientific principles to optimize the interaction between humans and their working environment. Poor ergonomic design causes over 1.8 million musculoskeletal disorders annually in the US alone, costing employers more than $20 billion in workers' compensation. Understanding biomechanical limits, thermal comfort zones, and cognitive load factors is essential for safe, productive workplaces.

These simulations let you calculate safe lifting limits with the NIOSH equation, model thermal comfort using Fanger's PMV method, optimize visual display parameters, assess repetitive strain injury risk, and design ergonomic workstations — all with real-time interactive controls and standards-based models.

5 interactive simulations
