Keyboard latency probe / 键盘延迟测试

Keyboard latency probe. This web page is meant to test two aspects of your keyboard: Its latency (through a reaction time test), and Its tap duration distribution (through a paced tapping test). 键盘延迟测试。本网页旨在测试您键盘的两个方面：延迟（通过反应时间测试）以及按键持续时间分布（通过节奏敲击测试）。

The two types of test (reaction time and paced tapping) are intermixed during the test. When starting the test, you will first have a reaction time block, then a tapping block, then a reaction time block again, until you’ve had seven blocks of each. Each block takes about 30 seconds to finish, meaning the total test time is 3.5 minutes. When the test is done, please describe your keyboard setup and then press Send to submit your results. 测试过程中会交替进行这两种测试（反应时间和节奏敲击）。开始测试后，您将先进行一个反应时间测试环节，接着是一个敲击测试环节，然后再次回到反应时间测试，直到每种测试各完成七个环节。每个环节大约需要 30 秒，总测试时间约为 3.5 分钟。测试完成后，请描述您的键盘配置，然后点击“发送”（Send）提交结果。

Multiple keyboards: If you have multiple keyboards (e.g. both external keyboard and built-in laptop keyboard), or multiple ways of connecting your keyboard (e.g. both USB and Bluetooth) I would greatly appreciate if you run the test one time for each keyboard and way to connect it. Do not mix keyboards within a test. 多键盘用户：如果您有多个键盘（例如外接键盘和笔记本内置键盘），或者有多种连接方式（例如 USB 和蓝牙），我非常希望您能为每种键盘和每种连接方式分别运行一次测试。请勿在同一次测试中混用键盘。

Reaction time test: The first test that runs is a reaction time test. When it starts, the big rectangle will say “wait…” and then after a random amount of time switch colour to green. When it does, you are supposed to tap any key as quickly as possible. 反应时间测试：首先进行的是反应时间测试。测试开始时，大矩形框会显示“wait…”（请等待），经过随机时间后颜色会变为绿色。此时，您需要尽可能快地按下任意键。

Paced tapping test: The second test that runs is a paced tapping test. When it starts, you will see a blinking yellow dot. Tap any key as briefly as possible when the dot lights up. It is important that you don’t hold the key down, but just briefly tap it. 节奏敲击测试：第二个测试是节奏敲击测试。开始时，您会看到一个闪烁的黄色圆点。当圆点亮起时，请尽可能短暂地按下任意键。请注意，不要按住按键不放，只需轻轻点击即可。

Technical issues: If you experience technical issues, or the instructions were vague, feel free to restart the test. Send only the data from the most successful run. I’m looking to test the abilities of your keyboard, not you as a person. Look at the rectangular area below and click start. 技术问题：如果您遇到技术问题或说明不够明确，请随时重新开始测试。仅发送最成功的一次测试数据即可。我的目的是测试您键盘的性能，而非测试您个人的反应能力。请查看下方的矩形区域并点击开始。

Test complete. Please describe the keyboard you used (e.g. “built-in laptop keyboard, ThinkPad X1”, or “external mechanical, USB” or “Apple Magic Keyboard, Bluetooth”): Send 测试完成。请描述您使用的键盘（例如：“笔记本内置键盘，ThinkPad X1”；或“外接机械键盘，USB”；或“Apple Magic Keyboard，蓝牙”）：发送

Reaction time (stimulus → keydown), ms 反应时间（刺激 → 按下按键），毫秒

Tap duration (keydown → keyup), ms 按键持续时间（按下按键 → 松开按键），毫秒
