OATS_201601 Injected Errors Study 2

Older Adults Text-entry Studies (OATS):
Our goal was to capture participants’ typing behaviour during input in a lab setting and determine the efficiency of the highlighting keyboard error support mechanism. In this experiment we introduced a new type of experiment, designed to overcome the problem of participants typing in very carefully (i.e. the “injected error” algorithm). This time the algorithm was modified to overcome some limitations encountered in a previous experiment (2015-04). The experiment involved only younger users.

老年用户文本输入研究（OATS）：
本研究旨在采集实验室环境下参与者的文本输入打字行为数据，以评估高亮式键盘错误辅助机制的使用效率。本次实验引入了一种新型实验范式，用以解决前期实验中参与者打字过度谨慎的问题（即「注入式错误」算法）。相较于2015年4月的前期实验，本次研究对该算法进行了优化，以克服其存在的部分局限。值得注意的是，本次实验仅招募了年轻用户作为参与者。
