The usability of four kinds of keyboards as regards touch and feel was evaluated by measuring the performance and eliciting the preferences of a total of 24 Japanese participants in a test that consisted of typing English text. It was found that quiet keyboards with an indistinct tactile feedback tend to give higher uncorrected error rates than keyboards with a distinct tactile feedback and clicking sound, while no significant difference in throughput was found among the four keyboards. As regards preference, the test participants were divided into two groups: those who preferred keyboards with a distinct tactile feedback and clicking sound, and those who preferred keyboards with an indistinct tactile feedback and no sound. Analysis revealed that these two groups also showed different sensations and preferences with respect to several aspects of the touch and feel of keyboards. This result suggests that suppliers of computer keyboards should provide two kinds of keyboards, with distinct and indistinct tactile key switches, in order to satisfy as many users as possible.
通过测量24名日本参与者在输入英文文本测试中的表现并询问他们的偏好，对四种键盘在触感方面的可用性进行了评估。结果发现，与具有明显触觉反馈和按键声的键盘相比，触觉反馈不明显的静音键盘往往会产生更高的未校正错误率，而四种键盘在吞吐量方面未发现显著差异。在偏好方面，测试参与者被分为两组：一组更喜欢具有明显触觉反馈和按键声的键盘，另一组更喜欢触觉反馈不明显且无声音的键盘。分析表明，这两组在键盘触感的几个方面也表现出不同的感觉和偏好。这一结果表明，计算机键盘供应商应提供两种键盘，一种具有明显的触觉按键开关，另一种具有不明显的触觉按键开关，以满足尽可能多的用户需求。
