摘要

可用性测试是一种测量系统可用性的技术。它由许多变量组成，如任务、用户数量、评估器和其他元素。本文探讨了任务设计对可用性测试结果的影响。它描述了两种不同类型的任务如何影响结果。探索的类型是结构化任务和不确定任务。每种类型的任务似乎都会发现不同类型的问题。此外，在这项研究中，“五个用户”这个神奇的数字并没有解决85%的可用性问题。

Task Design: Its Impact on Usability Testing

Usability testing is a technique for measuring a system's usability. It consists of a number of variables such as tasks, number of users, evaluators, and other elements. This paper explores the proposal that task design can seriously influence the usability testing results. It describes how two different types of task affect results. The types explored are structured tasks and uncertain tasks. Each type of task seems to discover different types of problems. In addition, in this research, the magic number of "five users" fails to achieve the promised 85% of usability problems.
