Some important tasks, such as driving or attending lectures, need your full attention but it's easy to get bored and become drowsy. SleepWake is here to wake you up during such moments. The alarm will go off and the watch will vibrate intensively. A smart watch with the heart rate sensor is required. Samsung Gear Live, Moto 360 are the most compatible.

★★★★★ How does it work?

The watch measures your heart rate values through the optical sensor then sends to the server for analysis. When you are drowsy and trying to focus on your task at hands, your heart rate variability follows a distinctive pattern. By analyzing this pattern, it is possible to estimate your level of drowsiness wherever you are, with no special gear other than your watch.

Algorithms used to analyze heart rate follows recommendations of European Society of Cardiology (ESC) and the North American Society of Pacing and Electrophysiology (NASPE). The current accuracy rate is more than 90%.

The watch app will learn and get better down the track when it measures your own heart rate patterns frequently and updates the tracking results.

★★★★★ How background monitoring is done? Does it drain battery?

The app tracks your movements and heart rate patterns to realize when you starts to get sleepy, it then increases the number of reading times to cover more often. On the other hand, it scales down monitoring sessions when you just wake up after a good sleep ^^. By intelligently triggering sensors at the right times only, SleepWake conserves the watch battery. A fully-charged watch can usually run a whole day long with the app running in the background.

★★★★★ What watch does the app support?

It only works with watch that runs on Android and has an optical heart rate sensor facing your wrist (such as Samsung Gear Live, Moto 360) so it can reads heart rate automatically. It doesn't work with watch with no sensor or watch that requires manual handling for every read (for example, Asus Zen Watch).

The app does NOT run on Tizen-based watches like Gear S, Gear 2, Gear 2 Neo yet.

一些重要的任务，例如驾驶或参加讲座，你需要充分重视，但它很容易感到厌倦，变得昏昏欲睡。 SleepWake这里是在这样的时刻，把你叫醒。报警器就会熄灭，手表会震动强烈。智能手表的心脏速率传感器是必需的。三星齿轮现场，摩托360顷最兼容。

★★★★★它是如何工作的？

手表通过光学传感器测量的心脏速率的值，然后发送到服务器以供分析。当你昏昏欲睡，并试图把重点放在你的任务在手，你的心脏心率变异遵循一个独特的模式。通过分析这种模式，就可以估算你的睡意水平无论你在哪里，有没有特殊的齿轮比你的手表等。

算法用来分析心脏率如下欧洲心脏病学会（ESC）和起搏北美和协会电（NASPE）的建议。当前的准确率是90％以上。

这款手表的应用程序将学习并获得更好的走下赛场时，它衡量自己的心脏速率模式和频繁更新的跟踪结果。

★★★★★背景如何监控呢？这是否耗尽电池？

该应用程序跟踪你的运动和心脏速率模式来实现，当你开始变得昏昏欲睡，然后它增加了阅读时间更频繁地覆盖数。在另一方面，它按比例缩小的监控会话，当你一个良好的睡眠后，刚刚睡醒^^。通过只在正确的时间触发智能传感器，SleepWake节省电池的手表。充足电的手表通常可以运行一整天长在后台应用程序运行。

★★★★★能做什么手表的应用程序支持？

它仅适用于运行在Android和具有光学心脏速率传感器对着你的手腕（如三星齿轮现场，摩托360）手表因此它可以自动读取速率心脏。它不工作，手表，没有传感器或手表需要手动操作，每读（例如，华硕禅观察）。

该应用程序不会对Tizen为基础的手表状齿轮S，齿轮2，齿轮2新运行呢。

★★★★★反馈多的欢迎！

该应用程序是持续改善，任何反馈？请发送电子邮件至service@sleepwake.me
