Cushman, William H., Ojha, Purnendu S. and Daniels, Cathleen M. (1990): Usable OCR: What are the Minimum Performance Requirements?. In: Carrasco, Jane and Whiteside, John (eds.) Proceedings of the ACM CHI 90 Human Factors in Computing Systems Conference 1990, Seattle, Washington,USA. pp. 145-151.

Forty-two subjects used a microcomputer and word processing software to type and proofread a 450-word document and then to correct errors in a number of other documents (of the same length) that had been created by OCR simulation [i.e., the documents looked like those typically obtained when using an optical character recognition (OCR) device for text entry]. The "OCR documents" contained both recognition errors (substitution errors, insertion errors, and deletion errors) and unrecognized characters. The percentage of characters requiring correction was varied from document to document. Text entry by OCR was found to be faster than manual entry (i.e., typing) if the OCR device can correctly recognize at least 94% of the individual alphanumeric characters. However, 98% correct recognition and computer-assisted proofreading were required in order to consistently obtain finished documents that had no more residual errors than typed documents.

Cushman, William H. and Derounian, Robert (1988): Design and Testing of a Facility for Two-Way Video Teleconferencing. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 224-228.

This report describes the design and testing of a facility for two-way video teleconferencing. The design process began by developing and distributing a survey to assess the needs of potential users, to develop a "user profile" for these individuals, and to determine their willingness to consider video teleconferencing as an alternative to "in person" meetings. In addition to the survey, design data were obtained from the human factors literature, site visits, interviews with users of existing video teleconferencing rooms, and rapid prototyping and user testing of alternative designs. Construction of the facility has been completed, and over 200 users have been trained to use the equipment. User reaction has been very favorable, with a majority of users expressing a desire to use the facility again.
