Study Notes
Anthropometrics
- Design must prioritize human needs, ensuring products are appropriately sized for user comfort.
- Designers rely on anthropometric data, which contains measurements of individuals across various ages and sizes.
- Consideration of user interaction is critical to avoid misuse and enhance usability.
- Variations in anthropometric data impact industries like fashion, influencing garment sizing for specific markets.
Human Factors
- Represents the intersection of ergonomics and anthropometrics.
- Aims to reduce user stress and fatigue, improve safety and ease of use, enhance comfort, and boost system performance and reliability.
Ergonomics
- Focuses on the scientific relationship between humans and the design of systems, objects, and environments.
Physical Ergonomics
- Centers on work-related aspects such as posture, workspace layout, material handling, and prevention of musculoskeletal disorders.
- Involves measurements of body size, strength, and physical capacity.
Cognitive Ergonomics
- Relates to mental processes (perception, memory, reasoning, motor response) influencing interactions between humans and system elements.
Organizational Ergonomics
- Examines factors such as communication, work design, shift management, teamwork, and quality control.
Anthropometric Data
- Divided into Static Data (measurements in fixed positions) and Dynamic Data (measurements during physical activities).
- Static data includes metrics like height and arm length, while dynamic data involves tasks that require movement.
Tools for Collecting Anthropometric Data
- Includes sliding calipers, cloth tape, sitting height meters, and stadiometers.
Understanding Percentiles
- Percentiles aid in assessing whether measurements correspond to the average or deviations from it.
- Important percentiles include the 5th, 50th, and 95th, as well as ranges like 2.5th to 97.5th.
Clearance in Human Factors
- Defined as the minimum distance necessary for user access through spaces; important for designing emergency exits.
Reach in Human Factors
- Also known as the workspace envelope, defines the 3D area where physical activities are performed at a fixed location.
- Designed for the 5th percentile user to ensure accessibility for 95% of the population.
Adjustability in Design
- Recognizes the need for products to accommodate various user sizes; examples include adjustable ironing tables.
