6. A Simple Model for Considering the Complex Soldier System USER TOOLS TASK ENVIRONMENT
7. Key Challenge – User Complexity and Variability USER Military Occupation Role (rifleman, leader) Perceptual Capabilities : Visual Acuity Colour Vision Eye Dominance Hearing Age Gender Physical Attributes : Size & Shape Strength Fitness Level Handedness Psychological/Cognitive Capabilities : Intellect, Cognitive Style, Information Processing, Decision-making capability, Resilience, etc. Education Training Experience Skills State : Fatigue Hydration Motivation Emotional Arousal
8. Key Challenge – Task Complexity and Variability USER TASK Type of Mission Phase of Mission Perceptual Tasks (observe) Cognitive Tasks (orient, understand, decide) Physical Tasks (act) Concurrent Tasks Time Pressure Threat Environment Individual & Team Tasks
9. Key Challenge – Equipment Complexity and Variability USER TOOLS TASK Compatibility vs Integration, Modularity, Scalability, Individual Clothing & Personal Equipment Collective / Team Equipment Legacy vs Future Weapon, Transport, Communication & Battle Management Systems Utility Usability Modality Salience
10. Key Challenge – Environment Complexity and Variability USER TOOLS TASK ENVIRONMENT Terrain : Slope, Surface, Cover Weather : Temperature Humidity Precipitation Cultural Organizational Training Threat Future Security Environment Lighting : Day/Night Obscurants Noise : Sound Discrimination & Localization Speech Intelligibility Hearing Protection

20. Percentiles vs Population accommodation For a given male head breadth (153mm) Head length ranges more than 30 mm (183 to 215 mm)
What is Human Systems Integration? A Model for Considering the Soldier as a System Introduction to Workshop Themes Physical Ergonomics and Integration on the Soldier Cognitive Ergonomics and Integration on the Soldier System Architecture & Interoperability (External Integration) Physical Ergonomics & Integration Challenges Scope – anthro, exercise/work/thermal physiology, physical environment (Noise, Lighting, Thermal, Vibration), biomechanics, load carriage, displays and controls Integration Challenges – see Visioning Workshop slides protection, load,
Human Systems Integration : the technical process of integrating the 5 HSI domains with a materiel system to ensure safe, effective operability and supportability of the system: Human Factors Engineering Manpower and Personnel Training System Safety Health Hazard Assessment About overall effectiveness of human-operated systems—socio-technical systems Part of a systems engineering approach
Applicable to all systems having a human interface, including hardware and software HFE application to systems design improves ease of use, system performance and reliability & user satisfaction while reducing operational errors, operator stress, training requirements, user fatigue, and product liability HFE is distinctive in being the only discipline that relates humans to technology

No such thing as a 5 th , 50 th or 95 th percentile soldier! When you hear/read this expression, you need to immediately ask – for which dimension? Canada prefers to specify population accommodation in its acquisition specifications: The “ x ” shall accommodate “ x ”% of the “ x ” population Accomodation implies not only USER fit/adjustability, but also ability to perform the range of TASKS to specific performance standards under the range of ENVIRONMENTS, and with the range of clothing and equipment (TOOLS) with which the item must be compatible
Head- Supported Mass Studies: Addition of 0.5, 1.0 and 1.5 kg mass at user preferred CoM Tests included static stand, obstacle course, ½ day platoon missions Measures included EMG & accelerometry, soldier performance, ratings of acceptability Weapon Mass Properties Study Addition of 1.5 kg, 3.0 kg and 4.5 kg to C7 weapon base weight Each weight at each of 3 centres of mass
Hit probability when the target passes a 10m wide opening at maximum speed Carrying loads of 20, 32.5 or 45 kg Exposure times when running upright or crouched are marked by vertical or solid red lines respectively
