A quantitative assessment approach for user operation performance grounded in cognitive models

Abstract: User task performance is the most crucial indicator reflecting the effectiveness of human-computer interaction design in information systems. The evaluation results of user task performance can directly reflect the design effectiveness of information systems. However, there is currently no quantitative evaluation method for task performance. This research paper focuses on the evaluation of user task performance in information systems. By conducting ergonomic experiments based on the trackball operation method, the meta-operation time in the GOMS model is revised and supplemented. Based on the revised results of the GOMS model, a quantitative evaluation method for task performance is studied. The results show that this method can obtain quantitative evaluation results of user task performance, which can support the improvement of human-computer interaction design in information systems.

Keywords: Human-computer interaction design, operational performance, quantitative evaluation
