Abstract

On the basis of Cooperative Task Simulation Model(CTSM),this paper proposes a cognitive cooperation walkthrough inspection technology,and designs its walkthrough process algorithm.The first stage comparison experiment validates that the usability evaluation technology is suitable for cooperation software system at early design,and it achieves low cost and high efficiency.The number of evaluators is increased in the second-stage experiment.How the quantity and individual performance of evaluator affect the evaluations result is analyzed.The number of samples to gain the highest cost-effective ratio for general evaluation is suggested.
