GUI DESIGN FOR WWW WITH MENTAL WORK LOAD

我们开发了该系统来测量WWW操作中心率变异性与脑力劳动负荷之间的关系，发现当用户操作WWW的响应时间较长时，心率变异性的一些参数如Tp、Xa、Xc与脑力劳动负荷之间存在弱相关性，但根据WWW的设计，这种相关性并不明显。心理工作负荷问卷调查结果表明，无火焰WWW比有火焰WWW更容易操作，层次较小的WWW操作脑力劳动负荷较小。但心率变异性参数并不能很好地反映出这种差异。

We deveIoped the system to measure the relationship between the heart rate variability and the mental work load in WWW operation.It is found that there are weak correlation between some parameters of the heart rate variability such as TP, Xa and Xc and mental work load when users operate WWW with long response time.However these correlations are not clear according to the WWW designs. The results of questionnaire about mental work load shows that they can operate WWW with no flame more easily than one with flame and the mental work load is less when they operate WWW with little hierarchy. But such difference is not found by the parameter of the heart rate variability clearly.
