如何让喜欢的应用程序刷卡键盘 [英] how to make swipe keyboard like app

问题描述

我想知道这背后是像了Swype键盘或的Nexus 4的股票键盘手势键盘tecnique。我GOOGLE了很多，为此，但找不到什么有用的。

i'd like to know which is the tecnique behind a gesture keyboard like Swype Keyboard or Nexus 4 stock keyboard. I've googled a lot for this but can't find nothing usefull.

我明显发现的例子中的SDK示例为简单kayboard中，并开始与在为了理解一个IME显影背后的原理。现在我才明白事情是如何工作的，我想明白怎么样的键盘作品。我认为它有一些东西做的手势，我研究过，但它看起来是错误的方式。所以我提出这个问题，什么样的技术是基础。难道是绘画？我需要undestand画布ECC？

I obviously found the example in the sdk samples for the simple kayboard, and started with that in order to understand the principle behind a IME developing. Now that I understand how things works, I'd like to understand how that kind of keyboards works. I thought it had something to do with gestures, and I studied them, but it looks as the wrong way. So I'm asking this question what kind of technique is the base. Is it drawing? Do I need to undestand Canvas ecc?

感谢

推荐答案

那么，既然我帮助撰写了Swype我给你一点帮助这里。你将需要花很多时间去研究DSP（数字信号处理），以了解如何评估传入的触摸数据，并找出其中字母（这是比你想象的更复杂，因为人们没有了Swype干净信不超过letter他们环路和卷曲）。 Swype的背后的算法是由我们的创始人超过十年的研究的最终结果。

Well, since I helped write Swype I'll give you a bit of help here. You're going to need to spend a lot of time studying DSP (digital signal processing) to understand how to evaluate the incoming touch data and figure out where letters are (this is more complicated than you think, because people don't Swype cleanly letter to letter- they loop and curl). The algorithms behind Swype were the end result of over a decade of research by our founder.
