Abstract
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).
