Measurement of user performance and attitudes assists the initial design of a computer user display and orientation method

Abstract

With graphic user interface prototyping environments, one can obtain preliminary user attitude and performance data, even before application programming is begun. This may be helpful in revising initial display and orientation methods, while obtaining user interest and commitment before actual programming and clinical testing.

Comparing two anesthesia information management system user interfaces: a usability evaluation

“…23,24 The focus of prior work related to AIMS human factors has been on comparing paper-based documentation with electronic documentation rather than on comparing two electronic solutions. 10 One of the important aspects of this study was the use of a multimodal approach in user interface evaluation that allowed for the analysis of specific aspects of the design. Review of screen recordings provided an objective evaluation of specific changes, while subjective input was obtained from the ad hoc survey.…”

“…A power calculation was not performed a priori. A sample size of 20 was chosen based on prior work [10][11][12][13][14][15][16] due to a lack of an estimate of measured effect size.…”
