Schumacher, Robert M., Root, Robert W., Wieringa, Douglas R. and Lew, Gavin S. (1995): The Human Factors Involved in Designing an Online Reference System. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 218-222.

Throughout the last two years, we have been involved in an ambitious plan to move support documentation to an electronic document delivery system at Ameritech. The purpose of this panel is to provide a discussion of the human factors issues involved and the effort required to move from a paperbased environment to an electronic document management and delivery system. The starting state of Ameritech's documentation was similar to that of many large companies that have complex processes. The documents were written by dozens of authors over several years and varied widely in quality. Standards were loosely followed, if at all, and users were continually frustrated by their inability to find information. This unwieldy environment had countless direct and indirect impacts on customers, as well as on the bottom line. As we scoped the project we discovered that our challenges were legion: * Design a new document specification that fit the needs of the users, worked well on-line, exploited the capabilities of electronic information (e.g., hypertext), and could be put together by our current author population; * Develop and implement a collaborative authoring and work flow process to support document creation: * Establish standards for writing and document rendering: * Design an efficient, usable user interface to the electronic document: * Move tens of thousands of pages of hard copy to an online system: and * Get the system introduced and accepted by users -- not to mention wean them away from paper. In this panel, we hope to stimulate discussion around a variety of these topics. We will discuss four key areas: task analysis, process changes, authoring requirements, and user interface design.

Schumacher, Robert M. and Lund, Arnold (1993): Development of a Usable Graphical User Interface Design Guide. In: Proceedings of the Fifth International Conference on Human-Computer Interaction 1993. pp. 21-26.

A corporate reality, that poor user interface design negatively affects employees and customers, led us to develop a graphical user interface design guide. We discovered in developing the document that current reference materials are not very helpful and are hard to use. We considered several areas for improvement, including using copious examples, providing behavioral rationale for choice of interface controls, etc. Our experiences so far have been positive and we hope will result in achieving our desired results of improving overall interface design.

With the growing use of the telephone as an input device, human factors designers need more human performance data on how quickly and accurately users can learn and execute alternative data-entry input strategies, as well as indications of what strategies users prefer. This study assesses five different strategies for entering alphabetic codes from a telephone keypad.

Schumacher, Robert M. and Gentner, Dedre (1988): Remembering Causal Systems: Effects of Systematicity and Surface Similarity in Delayed Transfer. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 1271-1275.

Transfer between functionally isomorphic devices can be viewed as a kind of analogical mapping. In this research subjects learned to operate a computer-simulated device and then transferred to a functionally-equivalent device, either immediately or after a delay of one week. Two factors were varied: the systematicity, or causal coherence, of the original device mode; and the transparency, or degree of surface similarity between corresponding components in the two devices. The results showed effects of delay, systematicity and transparency. Transfer performance was better in the immediate than in the delayed condition. Both systematicity and transparency improved performance in both immediate and delayed conditions.
