Human Factors in DesignAppendix C of Robot Report
Requirements for Appendix C
•1 page (400-500 words) for each member of the team
•Discuss how to modify the design of a companion robot to serve a child or a 65+ adult
•Base your design decisions on information from reliable literature (see examples in Canvas: Robot Module - Appendix C: Robot Readings)
What are Human Factors (HF)?
And why do engineers need to be concerned about them?
Human Factors is the application of knowledge about human characteristics to design
•Physical▫Strength, size, reaction time, endurance,
frailty, eyesight, fine motor skills•Social/Emotional/Cultural
▫User preferences (simplicity, reliability, aesthetics, safety, cost, etc.), culturally-based behaviors (reading, speaking), acceptance
•Cognitive▫Understanding cause and effect, user
interface, interpreting emotions and intentions
Human factors design principles
Senses- Vision - Hearing
Psychomotor- Hands
Input Devices- Buttons
Output- Display - Sound
INTERFACE
US Department of Veteran Affairs
Human Factors also acknowledge that humans are fallible.., people make mistakes!
So why consider Human Factors?
•Improve efficiency •Ensure safety•Increase human performance (i.e.,
productivity)•Minimize costs (economic, legal, social)Especially critical to space/air, nuclear and healthcare industries
Human Factors design considerations affect product effectiveness, safety, and ultimately, desirability.

Example: Healthcare-related technology is rapidly growing
You hope Human Factors were considered in the design of this equipment
Human Factors (ergonomics) integrates knowledge from multiple fields
•Engineering•Psychology•Physiology/Kinesiology•Biology•Anthropology
SJSU has a human factors program in the Industrial and Systems Engineering department
