USABILITY AND HUMAN FACTORS LECTURE 5 1 INTRODUCTION Human factors is a discipline that examines how people interact with technological systems, particularly in the context of their impact and usability. It focuses on a wide array of health-related technologies and systems utilized by a diverse group of individuals including medical professionals, hospital staff, and patients. 2 ELECTRONIC HEALTH DEVICES & HEALTH RECORD SYSTEMS 3 HUMAN FACTORS AND HCI REDUX (REDUX=REEXAMINED=REASSESSED) Differences: Histories, journals, academic and professional societies HCI focused on computing and innovative design HF focused on any system and greater emphasis on work/workplace and on devices Patient Safety is a core issue 4in HF 4 WHY IS HUMAN FACTORS INCREASINGLY IMPORTANT Diversity of user groups Complexity of systems Increased use of technology Increased “costs” of human error Societal emphasis on well-being and quality of life (e.g. The car industry. There is a general perception that Japanese and European cars are of greater quality and this has hurt the sales of North American cars.) 5 HUMAN FACTORS FOCUS AND GOALS Focus Human beings and their interactions with products/equipment, tasks, environments Micro, macro, ambient: Micro: This level focuses on the direct, small-scale interactions between a person and the products or equipment they use. For example, the design of a computer keyboard and how the keys feel under the fingers of the office worker. If the keys are too hard to press or awkwardly spaced, it could lead to discomfort or typing errors. 6 HUMAN FACTORS FOCUS AND GOALS Focus (Cont. Macro: This level looks at larger systems and how tasks are structured within them. In our office example, this could involve how the worker's job is designed, including their role in the company, the workflow, or how their work is organized throughout the day. If the workflow is inefficient or the tasks are poorly designed, it could lead to decreased productivity or job dissatisfaction. Ambient: This level considers the overall environment in which people interact with products and systems. In the office, this could refer to the lighting, noise levels, room temperature, or even the culture of the workplace. Poor ambient conditions, 7 HUMAN FACTORS FOCUS AND GOALS Focus (Cont. In summary, human factors at the micro-level are about the details of interaction, at the macro-level are about the structure and organization, and at the ambient level are about the environmental context in which people and systems operate. 8 HUMAN FACTORS FOCUS AND GOALS Goal Design systems and system components to match the capabilities and limitations of humans who use them Optimize working & living conditions (To make technology better, we change or create it to fit what people are good at and not so good at. This makes sure the technology is easy to use and helps people work better. Studying how our 9
