安全原型——
littleBits
和
cloudBit
2007
年，随着第一代
iPhone
的发布，苹果公司单枪匹马扰乱了整个智能手机行业。从
一个局外人的角度来看，
2007
年公布的
iPhone
可能就是第一款面向公众的成熟产品。
然而，最初的设计理念是最终要生产出一部触摸感应的平板，让用户远离键盘。当乔布
斯看到平板电脑的原型时，他就决定首先在智能手机上实现这一技术。
原型可以帮助我们将智慧集中在我们构思产品的真正意图上，帮助我们深入考虑我们思
路的相关性。创建原型的伟大之处在于：创建原型的过程能够帮助我们提前发现最终产
品设计上存在的潜在缺陷。原型也能够帮助我们对不同版本的思路进行测试，最终可能
会产生一个完全不同的思路，与最初的设计完全不一样，比如苹果和乔布斯的例子。
有很多平台和工具可以帮助个人以最小的成本和努力实现物联网产品的创意原型。本章，
我们就来集中讨论一下
littleBits
平台，该平台是市场上最简单最优雅的原型解决方案。
littleBits
中包含很多“磁性”模块，它们可以像乐高积木一样摆放在一起，几秒钟就能
够创建出一个原型。我们将使用
cloudBit
模块构建一个简单的，可以通过
SMS
消息发
送报警的无线门铃。
当你完成原型设计之后，我们来看看与
littleBits
相关的安全问题，这样我们就会了解到：
在真正生产之前的产品后续迭代过程中，需要采取的安全控制措施有哪些。这一练习的
目的是模拟厂家都会经历的真正的产品生产过程，从最初的产品原型开始，这样我们就
能够仔细考虑如何在正确的时间点将安全控制措施嵌入到产品中去。 ...
