This book is a senior-level college text intended for engineers and behavioral scientists needing an integrated approach to the incorporation of human factors in system design. It is organized around a 4-stage system-design process: (1) System Planning and Analysis, (2) Preliminary Design, (3) Detail Design, and (4) Test and evaluation(T&E). The initial stage comprises Chapter 1, The Role of Human Factors in System Development; Chapter 2, System Analysis; Chapter 3, ...
This report describes both conceptual and empirically derived models pertaining to the layout and grouping of information within display panels and display screens. Several of the models reviewed are also applicable to the spatial organization of controls and displays. Principles relating to centrality of location, symmetry clutter, frequency of use, sequence of use, relative importance,.and relatedness are considered. The models are organized into three areas: (a) physical arrangements of the ...
Video display terminals (VDTs) have been in use for several decades. Early VDT examples (e.g. radar terminals) reflect a military origin. The first mass produced VDT's appeared in the early 1960s, and were used for on-line data entry in interactive applications, such as airline reservations systems. Since then, advances in microelectronics have significantly enhanced the capabilities of the VDT, while simultaneously reducing unit cost. Presently, VDTs are used to convey ...
This report describes devices which allow the user to indicate spatial locations and movements on a computerized display, including touch screens, light pens, graphic tablets, mice trackballs, and joystics. These devices have demonstrated their effectiveness in pointing and selecting among graphical display items, such as icons, menus, and on-screen "toolbars." However, these devices have been shown to be less appropriate for other tasks, such as alphanumeric data entry and editing. ...
