What is Usability? • Usability means how useful, usable, and satisfying a system is

What is Usability? • Usability means how useful, usable, and satisfying a system is for the intended users to accomplish goals in the work domain by performing certain sequences of tasks (Zhang & Walji, 2011) • “Usable” has three subcomponents: – Learnability – Efficiency – Error tolerance (National Center for Cognitive Informatics and Decision Making. ”What is Usability? ”, n. d. ) 9

Usability Principles • Visibility of system status • Match between the system and the

Usability Principles • Visibility of system status • Match between the system and the real world • User control and freedom • Consistency and standards • Error prevention ("10 Heuristics for User Interface Design: Article by Jakob Nielsen", n. d. ) • Recognition rather than recall • Flexibility and efficiency of use • Aesthetic and minimalist design • Help users recognize, diagnose, and recover from errors • Help and documentation 10

Human Computer Interaction (HCI) and Human Factors • Basic & Applied Discipline – Study

Human Computer Interaction (HCI) and Human Factors • Basic & Applied Discipline – Study of people using computers to work – People, systems, tasks • Ergonomics & Human Factors – User performance in context of any system – Computer, mechanical or manual • Understanding – Humans in relation to their use of technologies 11

HCI and Health Information Technologies • Enormous advances in health information technologies in the

HCI and Health Information Technologies • Enormous advances in health information technologies in the last decade – Potential for improved healthcare • Clinicians & patients employ health information technologies – Current designs are suboptimal • Increasingly, there are more options 12

Why it May Matter to You • Technology is a potential source of error

Why it May Matter to You • Technology is a potential source of error and can compromise patient safety • Position to make a difference in product selection • The best technologies have some deficiencies – Better and worse choices 13

People and Technology, Studies of Technology Summary – Lecture a • Social and cognitive

People and Technology, Studies of Technology Summary – Lecture a • Social and cognitive consequences of new technologies • Usability and usability principles • Human computer interaction and human factors as a discipline • Why these disciplines matter in the context of health information technologies • NEXT: Patient safety, introduction to design and user-centered design 14
