When the question is bigger than a software license.

iHuman can act as your human-performance engineering team. We can define the study, build or import the digital environment, select the population, run the analysis, validate where needed, and deliver decision-ready results.

Human Systems Integration

Reach, vision, clearance, controls, seating, ingress/egress and population accommodation.

Equipment & PPE Studies

Armor, helmets, backpacks, weapons, load carriage, fit, mobility and tradeoffs.

Biomechanics & Performance

Joint loads, spine loads, strength, balance, fatigue, physiology, endurance and task demands.

Motion Capture & Validation

Protocol development, motion capture analysis, model calibration and experimental comparison.

Custom Model Development

New tasks, populations, physiology models, analysis modules, optimization studies and workflows.

Software & Integration

APIs, plugins, automation, customer interfaces, data pipelines and engineering-system integration.
