Users frequently commit typing errors due to input language mode confusion (ILMC) when switching between multiple languages. This study evaluated two mode display cursors (MDCs) as a potential solution to ILMC: the monochrome and color-changing MDCs. Two experiments were conducted to evaluate the two MDCs in different dimensions of usability. Experiment 1 evaluated the effects of MDCs on ILMC and related typing errors and Experiment 2, on self-reported preference, acceptance and annoyance. In Experiment 1, 45 participants were divided into three groups, that each performed multi-language typing using an ordinary mouse cursor and the two MDCs. The color-changing MDC was found to significantly reduce ILMC and related typing errors compared to the ordinary mouse cursor (p < .001). In Experiment 2, 30 participants performed three typical computer tasks using both MDCs. The mean annoyance rating was significantly larger for the color-changing MDC than for the monochrome MDC (p = .037).
用户在切换多种语言时，由于输入语言模式混淆（ILMC）经常会犯键入错误。本研究评估了两种模式显示光标（MDC）作为解决 ILMC 的一种潜在方法：单色和变色 MDC。进行了两项实验来评估这两种 MDC 在不同可用性维度上的效果。实验 1 评估了 MDC 对 ILMC 和相关键入错误的影响，实验 2 则评估了自我报告的偏好、接受度和烦恼度。在实验 1 中，45 名参与者被分为三组，每组使用普通鼠标光标和两种 MDC 执行多语言键入。与普通鼠标光标相比，变色 MDC 显著减少了 ILMC 和相关键入错误（p<0.001）。在实验 2 中，30 名参与者使用两种 MDC 执行了三个典型的计算机任务。变色 MDC 的平均烦恼评分明显高于单色 MDC（p=0.037）。
