Penguin robot helps researchers get close and personal http://www.theguardian.com/science/animal-magic/2014/nov/03/penguin-robot-behaviour My robot project is this far A. All done robot leaves arena with green beacon B. Can find green beacon but cant leave arena
C. Can find red beacon and turn it off but cant find green beacon D. Can find red beacon but cant turn it off E. Cannot find red beacon Human Factors in Design 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
Man Machine Interface Human Cognitive Action Interface/Interaction
Sensory Machine Display/ Configuration Machine Processing Control

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. Source: FDA Medical Device Use-Safety
