Participants will… Understand the ANSI/HFES 100-2007 human factors standards for creating an ergonomic computer workstation. Understand some of the challenges and solutions for using computers in the hospital setting Understand some of the challenges and solutions facing mobile laptop users.

ANSI/HFES 100-2007: Human Factors Engineering of Computer Workstations Purpose To specify acceptable applications of human factors engineering principles and practices to the design and configuration of the human-hardware interfaces in computer workstations.

ANSI/HFES 100-2007 Application For computer workstations used regularly in office workplaces by users with normal perceptual and cognitive capabilities Moderate to intensive computer users Not intended for beyond the office workplace application Generalizations to other applications exceed the scope of this standard.

ANSI/HFES 100-2007 Scope User Diversity Applies to computer workstations for a wide range of users In general the physical dimensions and force requirements are designed to accommodate at least 90 percent of the North American population User Diversity Design is not intended to accommodate all users due to the very nature of diversity

ANSI/HFES 100-2007 Guiding Principles Enhance workstation usability by improving ease of use and ease of learning Facilitate user performance by encouraging task proficiency and error recovery Accommodate users of various physical sizes and expertise levels Maintain user performance by allowing postural changes that minimize static loads Promote user satisfaction by fostering product acceptance and product usage

ANSI/HFES 100-2007 Limitations Not intended for transient computer work situations (e.g., using a laptop computer during airplane travel) or to workstations specially configured for individuals with physical or cognitive disabilities Use of a portable device in an office setting, such as a laptop computer in a docking station, is not an example of transient computer work. This standard does not apply to operator health considerations or work practices Focus is to support operator performance through attention to the design aspects of the computer hardware and environment interfaces. No implications are made that conformance to this standard produces health-related outcomes.

This standard recognized that VDT users frequently change their working postures to maintain comfort and productivity. Four reference postures are used in this standard to represent a range of postures observed at computer workstations.
