Information Architecture - Steve Krug

  1. “Don’t make me think.”
  2. “It doesn't matter how many times I have to click, as long as each click is a mindless, unambiguous choice.”
  3. “Get rid of half the words on each page, then get rid of half of what is left.”

Steve Krug's concepts on usability are wise words for anyone designing any interactive interface, and whilst his writings were originally in reference to web based usability, the themes and ideas can easily be appropriated for a mobile platform.

Simplicity is frequently referred to as one of the key factors to good interface design, minimalising the potential for the end user to be confused or uninterested. Shortening the journey to information is not considered as important as making sure the journey itself is painless and intuitive. Everything from the wording of available options to the colour of the border on clickable boxes can influence the time it takes for a user to decide whether they want to click through or not.

In terms of the architecture of the application, it is my intention to maintain a visual sense of 'real estate', where imagery and structure is maintained across all of the application. In a practical sense, this allows users to become familiar with navigational aspects of the application as well as developing an understanding of location in relation to other forms of content. If the app was to have the home button in different places when moving from page to page then the end user will experience a very disjointed journey to any content that they desire.

Structurally, I intend to construct a narrow and deep architecture, with real estate similar to that of Twitter for example, with a home button always present, and a small selection of shortcuts at the bottom of the screen. This allows the rest of the screen space to be dedicated to the content of each page, as well as making sure the focus is on the appropriate material. Functionality is something that needs to be at an optimal point for this application to maintain its audience, and therefore each user function should be effortless, much like Krug's views on navigation. For general sub-headings within the application, I have written a short list, and these are current navigational signposts to content, or external sites.

Within each section there will be more content, however these are the headings that summarise their subsequent content in the most succinct manner.

-Home
-News
-Sports/Societies
-Deals
-Events
-Email
-Blackboard

Krug raises the idea that some users prefer to browse first, whereas some prefer to use search functions. I'll need to make sure that both types of user can satisfy their usage trends as quickly as possible from the point of opening the app.

As well as structural hierarchy, there is also the concept of visual hierarchy to consider. Do some menu options command more attention that others? Is the space used efficiently to inform the user about which information is the most important and/or relevant? Ensuring that font thickness, spacing, and even bordering is consistent with the intended portrayal. All these things will come with the design portion of the product, which is already underway.

In summary, getting visual design correct can be a tricky task, however the benefits are massive. If users experience good architecture and design then confidence in the application, brand, or product is instilled, moving towards improving the overall customer satisfaction.
