  1. In the Name of Allah, the Most Beneficent, the Most Merciful University and science ofFaculty of Scienc& Technology Engineering Department of Electronic Engineering Major: Biomedical Engineering Report about: Association for the Advancement of Medical Instrumentation AAMI By: 1-Sanad TaherAljably Under the supervision of: Dr. Eng. FadelAlakwa. 2010-2011

  2. AAMI Standard: This Association for the Advancement of Medical Instrumentation (AAMI) standard implies a consensus of those substantially concerned with its scope and provisions. The existence of an AAMI standard does not in any respect preclude anyone, whether they have approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard. AAMI standards are subject to periodicreview, and users are cautioned to obtain the latest editions.

  3. AAMI Human Factors Engineering Committee: • This Committee that considered for the design of a particular medical device with a user interface have a fitting must be derived from two standpoints: • human factors design process. • human factors design principles.

  4. Human Factors Design Process: 1- Scope. 2- Normative reference. 3- Definition. 4- Overview of the HFE process. 5- Planning the HFE process. 6- General recommendations for HFE design. 7- The human factor and the work space. 8- Signs, symbols, and markings. 9- Controls. 10- Displays. 11- Alarms and signals. 12- User-computer interface.

  5. 1- scope: 1.1 The benefits of HFE. 1.2 Avoiding design-induced error. 1.3 Improving usability.

  6. 2- Normative references: Go to Glossary of Shortcuts

  7. 3- Definitions: 3.1 anthropometry. 3.2 appearance model. 3.3 conceptual model diagram. 3.4 contextual inquiry. 3.5 criticality. 3.6 fidelity. 3.7 hazard analysis. 3.8 (HFE) 3.9 labeling. 3.10 operator. 3.11 prototype. 3.12 requirement. 3.13 risk analysis For the purposes of this recommended practice, the following definitions apply. 3.14 risk management. 3.15 simulation. 3.16 specification. 3.17 system. 3.18 usability. 3.19 usability goal. 3.20 usability test. 3.21 use error. 3.22 use environment. 3.23 user. 3.24 user interface. 3.25 user profile.

  8. 3-cont. Definitions: 3.1anthropometry: Scientific measurement and collection of data about human physical characteristics as well as the application of this data to the design and evaluation of systems, equipment, and facilities. 3.8 HFE: human factors engineering (HFE): Application of knowledge about human behavior, abilities, limitations, and other characteristics to the design of tools, machines, equipment, devices, systems, tasks, jobs, and environments to achieve productive, safe, comfortable, and effective human use 3.15 simulation: Go to the remainder
