Ergonomics is the science of designing a work environment so that it is convenient to use and does not prove injurious to health. It is used in the United States to describe the design and implementation of equipment, tools, and machines related to human safety, comfort, and convenience.
It is the study and design of a work environment that maximizes productivity by reducing operator fatigue and discomfort.
It considers physical stresses placed on joints, muscles, nerves, and tendons as well as environmental factors that can affect hearing and vision.
Poor setup of computer equipment leads to somatic complaints that include headaches, eyestrain, irritation, stress, fatigue, and neck and back pain.
Usability studies can be used to support IT in a number of ways. Which of the following are reasons to complete these studies in a health care setting? –assesses the adequacy of a design or redesign early in the systems life cycle, helps determine or clarify users’ requirements determination
Usability: the ease with which people can use an interface to achieve a particular goal. issue of human performance during computer interactions for specific tasks within a particular context. which deals with specific issues of human performance during computer interactions for specific tasks within a particular context. usability issues address the efficiency and effectiveness of an application. For example:
the ease of learning an application
the ease of using an application
satisfaction with using
efficiency of use
fit of the system to the task
the speed of task completion and errors that occurred during application use when determining which system or application would be best used on a nursing unit.
Heuristic Evaluation = discount usability evaluation method: to detect problems early in the design process, when they can be most easily and economically corrected.
Formal usability test: use either experimental or observational studies of actual users using the interface to accomplish real-world tasks.
Ergonomics: the design and implementation of equipment, tools, and machines related to human safety, comfort, and convenience. commonly refers to attributes of physical equipment or to principles of arrangement of equipment in the work environment.
