应用脑力负荷测量的设计能力评价方法

分析了设计能力与脑力负荷、设计时间和设计效果之间的关系,提出了定量评价的方法.参试者脑力负荷由NASA-TLX(national aeronautics and space administration-task load index)量表测量,设计时间由专门开发的程序统计,设计效果通过专家打分给定分值.基于所评价出的设计者的能力等级,采用支持向量机技术对新设计任务的设计时间进行了预测.预测值和实测值的对比结果显示二者没有明显差异,说明该方法所评价的设计能力等级是有效的.

An evaluation method of design ability using mental workload assessment

By analyzing the relationship between design ability and design time,mental workload,and design effect,an evaluation method of design ability is proposed.As far as the factors involved in such method are concerned,mental workload is measured by NASATLX(national aeronautics and space administration-task load index) scale,design time is acquired with a special program,and design effect is scored by expert.Then,the time spent on new design tasks based on the evaluated ability level is predicted by using suppor...
