This study focused on an innovative mobile input device model that integrated ergonomic design principles to create a chord keyboard for use in concert with pointing devices. We conducted usability tests to demonstrate the operating performances of such keyboards using keys with four characters per key. Twelve right-handed subjects between the ages of 20 and 30 years and with no wrist disability participated in the usability tests. We analyzed the resulting data to compare the differences among the means. The results indicated that keyboards with multiple characters per key created some confusion among users but that keys with multiple characters per key nonetheless resulted in better input performance.
本研究专注于一种创新的移动输入设备模型，该模型集成了人体工程学设计原则，创建了用于与指点设备配合使用的和弦键盘。我们进行了可用性测试，以展示使用每个键具有四个字符的键盘的操作性能。十二名年龄在 20 至 30 岁之间且手腕无障碍的右利手受试者参加了可用性测试。我们分析了所得数据以比较平均值之间的差异。结果表明，每个键具有多个字符的键盘使用户感到有些困惑，但每个键具有多个字符的键盘仍能带来更好的输入性能。
