4. What are Human factors? Human factors is the discipline that tries to establish a relationship between technology and the human. Human factors is the discipline that tries to establish a relationship between technology and the human. Human factors deal with the human behavior, abilities, limitations to the use of software, tools and other jobs to make their use easier.(Human Computer Interaction – HCI) Human factors deal with the human behavior, abilities, limitations to the use of software, tools and other jobs to make their use easier.(Human Computer Interaction – HCI)

5. Issues of Concern Identifying end-users and requirements Identifying end-users and requirements Understanding end-user psychology Understanding end-user psychology Quality and performance Quality and performance

6. Advantages + Higher user satisfaction +Lower user fatigue +Lower training time and costs +Lower product liability +Lower operator stress +Lower operating costs +Lesser operational errors +Greater system performance

7. Who implements Human factors? Interface designers Interface designers Engineering psychologists Engineering psychologists
