我们提出了两个实验来评估手腕佩戴的可穿戴触觉显示器(WTD)，这些显示器为移动用户提供易于感知的警报。第一个实验(2304个实验，12个参与者)关注的是触觉模式的知觉敏感性，结果显示，经过40分钟的训练，人们对24种触觉模式的辨别准确率高达99%。在24种模式中变化的四个参数(强度、起点、时间模式和方向)中，强度是最难区分的参数，时间模式是最容易区分的参数。第二个实验(9900个实验，15名参与者)关注双重任务表现，探索用户在视觉分心和不受视觉干扰的情况下感知来自两个移动设备(WTD和手机)的三个警报的能力。第二个实验显示，当视觉分心时，手机用户对收到提醒的反应会变慢，但WTD并非如此。
We present two experiments to evaluate wrist-worn wearable tactile displays (WTDs) that provide easy to perceive alerts for on-the-go users. The first experiment (2304 trials, 12 participants) focuses on the perception sensitivity of tactile patterns and reveals that people discriminate our 24 tactile patterns with up to 99% accuracy after 40 minutes of training. Among the four parameters (intensity, starting point, temporal pattern, and direction) that vary in the 24 patterns, intensity is the most difficult parameter to distinguish and temporal pattern is the easiest. The second experiment (9900 trials, 15 participants) focuses on dual task performance, exploring users' abilities to perceive three incoming alerts from two mobile devices (WTD and mobile phone) with and without visual distraction. The second experiment reveals that, when visually distracted, users' reactions to incoming alerts become slower for the mobile phone but not for the WTD.
