Human factors of interactive software

There is intense interest about human factors issues in interactive computer systems for life-critical applications, industrial/commercial uses, and personal computing in the office or home. Primary design goals include proper functionality, adequate reliability, suitable cost, and adherence to schedule. Measurable human factors issues include time to learn, speed of performance, rate of errors, subjective satisfaction, and retention over time. Specific human factors acceptance tests are described as a natural complement to hardware and software acceptance tests. Project management ideas, information resources, and potential research directions are presented.
