User input is an important component to help guide designers in producing a more usable product. Evaluation of prototypes is one method of obtaining this input, but methods for evaluating assistive technology prototypes during design have not been adequately described or evaluated. This project aimed to compare different methods of evaluating…

Guidelines are presented for achieving the human factors inputs to the TA (Technical Approach) in the design process. (For each Navy training device, a TA determination provides for the evolution of the necessary technology.) A method is described which allows correlation of instructional requirements with engineering design solutions. The three…

Research is reviewed on (1) ergonomic factors which affect handwriting performance, focusing on the student's grip on the writing implement, pressure on the writing instrument and surface, types of writing instruments, and writing paper; and (2) assessment of the legibility and speed of handwriting.

Four papers from the University of California at San Diego (UCSD) Project on Human-Computer Interfaces are presented in this report. "Evaluation and Analysis of User's Activity Organization," by Liam Bannon, Allen Cypher, Steven Greenspan, and Melissa Monty, analyzes the activities performed by users of computer systems, develops a…

This report is a collection of 11 recent papers by the Human-Machine Interaction Group at the University of California, San Diego. The following papers are included: (1) "Stages and Levels in Human-Machine Interaction," Donald A. Norman; (2) "The Nature of Expertise in UNIX," Stephen W. Draper; (3) "Users in the Real…

Volume 1 contains all the invited papers accepted for the symposium. The subject matter covered in the papers includes physiological, anthropometrical, psychological, sociological, and economic human requirements and methods of evaluation; physical requirements and methods of evaluation in mechanical, acoustical, thermal, dimensional stability,…

The paper presents a summary overview of the major methods by which human environments have been assessed and characterized. Six general types of dimensions are identified: 1) Ecological Dimensions which include both geographical and meteorological and architectural and physical design variables; 2) behavior settings, which are the only units thus…
