摘要

我们比较了正常学生和盲人学生阅读触觉饼图和触觉带图的准确性。研究人员向他们展示了一组带有个人分割比例的触觉饼状图和带状图，并要求他们回答这个比例。错误数和读取时间被测量为精度指标。对视力正常的被试的结果显示，饼状图的阅读误差总体上小于带状图的阅读误差，两者的阅读时间差异不大。除了阅读时间外，盲人参与者的结果与视力正常的参与者表现出相似的趋势。

Comparison of reading accuracy between tactile pie charts and tactile band charts

We compared the accuracy of reading tactile pie charts and reading tactile band charts with sighted and blind students as participants. They were presented with a set of tactile pie charts and band charts with individual division ratios and asked to answer the ratio. The number of errors and reading times were measured as accuracy metrics. The results from sighted participants showed that the error sizes in the reading pie charts were, on the whole, smaller than those in the reading band charts and that there was little difference between the reading times of the two charts. The results from a blind participant showed similar trend to those from sighted participants except for the reading times.
