這兩個概念有所不同，“資訊架構（IA）”主要與“認知”有關，即：人們如何處理資訊、如何分析不同資訊之間的關係；而“資訊設計（ID）”則與“感知”有關，即：人們如何將他們看到的和聽到的東西轉化為知識。

這兩種方式都需要不同的技能。“資訊架構師”來自各個領域，但我感覺其中大部分有語言學背景；而“資訊設計師”通常指向視覺藝術，因此，大部分資訊設計師來自同一個領域：平面設計。

“資訊架構”屬於抽象概念，它主要針對人腦中的資訊結構，而不是紙上或螢幕上的；而“資訊設計”則非常的具體，資訊設計師在設計過程中考慮的重點是顏色和基本形狀等具體資訊。

Differences between Information Architecture and Information Design

Between the two names we have different concerns. Information architecture (IA) is primarily about cognition, how people process information and construe relationships between different pieces of information. Information design is primarily about perception, how people translate what they see and hear into knowledge.

Both require different skills. Information architects come from a variety of backgrounds, but I sense that a majority of them display an orientation toward language. Information designers, on the other hand, tend to be oriented toward the visual arts. As a result, the majority of information designers come from exactly one discipline: graphic design.

Information architecture belongs to the realm of the abstract, concerning itself more with the structures in the mind than the structures on the page or screen. Information design, however, couldn’t be more concrete, with considerations such as color and shape fundamental to the information designer’s process.
