交互设计的实质

Interaction design is the art of facilitating interactions between humans through products and services.

这是Dan Saffer在Designing for Interaction中对Interaction Design的定义。我认为讲的非常好，他指明了：交互设计的本质是人与人之间的交互，而不是人与物之间的交互。人对物的操作和物对人的反应只是途径而已。就像Alan Cooper说的要透过Task达到Goal。Dan Saffer也表达了：It's about making connections between people through these products, not connecting to the product itself。

交互设计是设计的是：the behavior of products and services，也就是how products and services work。Dan Saffer说的非常好：Interaction designers should spend a great deal of time defining these behaviors, but they should never forget that the goal is to facilitate interactions between humans。

交互设计和其他涉及领域有很多共享的理念和practice，容易让人摸不清Interaction Design到底是什么，和其他设计decipline有什么区别。我们可以通过问这样一个问题来尝试解答：交互设计不是什么呢？Interaction design isn't about interaction with computers (that's the discipline of human-computer interaction) or interaction with machines (that's industrial design).
