In order to study the processes people employ in reading technical material and the ways in which information engineering can facilitate those processes, 13 adults, including electrical engineers, stockboys, secretaries, graduate students, and teachers, were asked to perform an assembly task by following concise, step-by-step instructions provided via a computer display screen. Subjects also had instant access to Hypertext, a detailed, hierarchically organized structure providing supplemental graphic and dictionary information at the touch of a light pen to the screen. The types of information seeking responses made by each subject were recorded. It was found that subjects as a group selected graphic information most often, followed by dictionary information; that subjects sometimes made rechecks of text or nontext information; that individuals varied in the directness of their approach, the frequency of their requests for graphics or dictionary information, and their use of long and short rechecks; and that there were difficulties in certain segments of the text, as indicated by the greater number of information searches around certain frames. Study methodology and results are described in this report, which also presents diagrams of information engineering systems and information search strategies, reproductions of sample computer frames, schematic representations of subject performance, a list of 10 references, and additional supporting materials.
