Dynamic Dimensions: Types of Movement Flexion - Bending Extension - Extending, straightening Adduction - Movement toward midline Abduction - Movement away from midline Lateral rotation - Rotation outward Medial rotation - Rotation inward Pronation - Rotation downward Supination - Rotation upward
Wrist/Hand Motions Flexion/extension
Wrist/Hand Motions Radial deviation/ulnar deviation Toward the thumb Toward the little finger
Wrist/Hand Motions Pronation/supination Palm downward Palm upward

Right Hand Grasping Reach Envelope (2)
Grasping Reach
Other Dynamic Dimensions Prone length, height Squatting height Overhead reach Thumb-tip reach Standing forward reach Standing lateral reach
Right Hand Static Force
Hand Force Other Muscle Power Data Prone position data Thumb / finger Leg, foot etc
Other Muscle Power Data Prone position data Thumb / finger Leg, foot etc
Use of Anthropometric Data Determine relevant dimension / parameter Define user population Select range of users to be accommodated Extract data from appropriate source Apply correction factors Apply dimension to design
Design for Clearance/Accommodation Design for the Large Person (Let the large person fit.)
Design for Reach / Accessibility Design for the Small Person (Let the small person reach.)
Design for Adjustability Design for Everyone
Other Design Design for the Average Person
Design Principles Design for the large person (clearance/accommodation) Let the large person fit. Design for the small person (reach/accessibility) Let the small person reach. Design for the average person Design for adjustability
