ABSTRACT

BSR/HFES 100 Human Factors Engineering of Computer Workstations (HFES 100) is a specification of the recommended human factors and ergonomic principles related to the design of the computer workstation. HFES 100 is primarily intended for fixed, office-type computer workstations for moderate to intensive computer users. These design specifications are intended to facilitate the performance and comfort of computer workers. HFES 100 addresses the interaction between the computer user and the hardware components of the operator–machine system. HFES 100 provides guidance as to how these individual workstation components are to be integrated into a whole or system that is ergonomically sound. It is possible to ergonomically utilize well-designed computer workstation components that individually conform to the specifications of HFES 100 yet combine them inappropriately. As an extreme example, a desk only designed for standing work might mistakenly be installed in an area where all other components were intended for sitting work. The chapter on Installed Systems is intended to prevent such mismatches. Given that the individual components and the system can accommodate a variety of users and postures, HFES 100 also provides guidance on how to accommodate an individual user. As an example, it provides guidance on how a chair that is designed to accommodate a variety of sizes of users and a variety of postures may be adjusted to fit an individual. Finally, it provides guidance regarding desirable conditions in the environment around the computer workstation.
