Penguin robot helps researchers get close and personal 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-System Interface Senses - Vision - Hearing Psychomotor - Hands


Output - Display - Sound Input Devices - Buttons 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. Source: FDA Medical Device Use-Safety

Enter Numbers Different Interfaces? Cell phone keypad Calculator keypad Early Calculator Industry standard in

the 1950s Basically, a mechanical adding machine Earlier models looked like cash registers

Rotary Phone Rotary Dial Bell Labs Study Research showed*: Easiest to master

Natural way to match letters with numbers * Human Factor Engineering

Studies of the Design and Use of Pushbutton Telephone Sets. Published July 1960, Bell System Technical Journal 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
