Study Notes
Human Factors in Design
- Human Factors pertains to integrating human behavior, abilities, and physical limits into design processes to enhance usability.
- Emphasis on "Fitting the Job to the Man" encourages designs that accommodate user capabilities.
- Aims to optimize efficiency, health, safety, and comfort through thoughtful design.
Considerations During Design Phase
- Experienced professionals advocate for appropriate tools based on specific jobs; for instance, using an eraser for drafting vs. a sledgehammer for construction.
Importance of Human Factors
- Enhances productivity by simplifying tasks and processes.
- Increases safety, comfort, and user satisfaction.
- Minimizes errors and fatigue, leading to improved performance.
- Reduces the learning curve, ensuring user needs are met.
- Supports a positive user perception of the product.
Challenges in Human Factors
- Human adaptability can complicate design, leading to variability in user interaction.
- Prevalent individual differences include observable features like size and strength, as well as cultural, stylistic, and skill variations.
Forms of Human Factors
- Anthropometric Factors: Focus on static dimensions and physical size to optimize human-machine interaction.
- Ergonomic Factors: Address dynamic interactions during repeated tasks to enhance comfort and safety.
- Physiological Factors: Engage with human sensory systems and physical responses to stimuli.
- Psychological Factors: Explore mental processes and activities related to product use.
Anthropometric Factors
- Requires attention to human physical dimensions for effective design.
- Importance of creating adjustable designs to accommodate varying physical attributes.
- Products should be designed for average users as well as extreme cases to ensure inclusivity.
Ergonomic Factors
- Derived from Greek, meaning the study of work; emphasizes safety, comfort, and efficiency in human-machine interactions.
- Human capability aligns with task requirements, requiring an understanding of operator's physical abilities and work conditions.
Operational Capability Considerations
- Effectiveness in task performance influenced by physical ability, range and speed of movement, and duration of activity.
- Environmental conditions, such as lighting and space, significantly affect usability.
Instrument Panel Design Example
- Prioritization of instrument visibility based on relative importance and frequency of observation.
- Instruments like airspeed and gyro must be prominently placed for easy access during operation.
Physiological Factors
- Involves understanding human sensations and responses across various systems, including neurological and muscular.
- Factors include visual, auditory, tactile, kinesthetic, and environmental responses.
Physiological Factors Implications
- Proper design must ensure optimal lighting and noise control for user comfort and performance.
- The sense of touch aids recognition and interaction, highlighting the value of tactile feedback in design.
Psychological Factors
- Address the mental engagement of users during the interaction with products.
