Research Abstract

This research was focused on the mental workload index as the measure for the efficiency relating to mental effort, which was a component of usability. The effective mental workload index as the objective and quantitative measure for the efficiency was discussed through three usability tests experiments.
From the results of these experiments it was suggested that the ratio of the pre-stimulus respiration to all respiration under the controlled respiration could be the effective index as the objective and quantitative measure for the efficiency.
