HFES 200 Human Factors Engineering of Software User Interfaces

Editor: HFES 200 Committee
Year Published: 2008

The objective of HFES 200 is to provide design requirements and recommendations that will increase the accessibility, learnability, and ease of use of software. The ultimate beneficiaries are the end users of software, whose needs motivated the design recommendations in HFES 200. The application of this standard is intended to provide user interfaces that are more usable, accessible, and consistent and that enable greater productivity and satisfaction.


Human Factors Engineering of Software User Interfaces consists of five parts:

  • HFES 200.1: Introduction
  • HFES 200.2: Accessibility
  • HFES 200.3: Interaction Techniques
  • HFES 200.4: Interactive Voice Response
  • HFES 200.5: Visual Presentation and Use of Color

HFES 200 Part 1: Introduction provides an overview of the content, explains relationships among the individual parts, and provides guidance on the relevance of individual parts to the development process so that designers may understand where and when to use the parts.


HFES 200 Part 2: Accessibility provides recommendations on features and functions of computer operating systems, drivers, application services, other software layers on which applications depend, and applications that increase the accessibility of applications for users with disabilities. Hardware is not specifically addressed by any recommendations; however, many hardware assistive devices may utilize recommended functions that are provided by operations system and application software. HFES 200 Part 2 has been extensively harmonized with the International Standards Organization (ISO) 9241-171 Software Accessibility Committee Draft released in the first quarter of 2005.


HFES 200 Part 3: Interaction Techniques incorporates material from ISO 9241 Parts 13 through 17 and is compatible with those ISO standards.


HFES 200 Part 4: Interactive Voice Response consists of completely new material that has not appeared in ISO 9241 standards.


HFES 200 Part 5: Visual Presentation and Use of Color incorporates material from ISO 9241 Part 12 and includes new recommendations on the use of color.
