Ixd Theory02 more important Principles

< More important principles among 10 Neilson’s heuristics >

#2 Match btw system and the real world 
#4 Consistency and standards

Among 10 heuristics, I assume #2 Match btw system and the real world  and #4 consistency and standards seems more important than others. In order to render a technology into service/product/new culture by creating/assigning purpose, hence creating a meaning, so that a user can understand the the benefit of it, revealing association is very important. This connection comes from one of the following two-part sets: 1. some degree of consistency between the user’s current life style and the new service; 2. consistency between the physical world and digital/intangible world; 3. consistency between what people know and they will newly learn; or, 4. merely consistency between what people have experienced and what they will experience. My diagram below shows further reasoning on this.

I’d like to articulate further about consistency which includes two aspects. One is internal consistency, which is articulated with the same control symbols that function in the same manner as the product line(e.g. Microsoft office).  Second is external consistency, which means designing conventions that cross cultures(e.g. the use of red to represent heat). I think these consistencies are conceptual tools and work as great segway among different concepts. A great strategy to introduce something new to users so they can use it easily is “Traditional + new”. If an aspect of a new product already exists, appropriate that language , or established meaning in the introduction of the new thing.

One thought on “Ixd Theory02 more important Principles

  1. Interesting blog entry. I don’t think Neilsen intended for his heuristic to be associated with creating meaning. His focus was on how you get someone to use something, but it is true that communicating the meaning/purpose of a product is something upon which designers must focus.

    I think it’s great that you are expressing your ideally visually in a diagram. I did find it a bit difficult to decipher, so I encourage you to explore ways you can can more clearly bring the reader along through your thought process. Perhaps try breaking up the diagram into small chunks that build on each other, with explanations for each chunk.
