Usability dynamic and static navigation

Navigation Part 3: Dynamic or static navigation

by on 24. Jul, 2008 in Information Architecture, Usability

For all of you who are not sure what the difference is, let me explain briefly:

A static navigation is always visible and when you click on the first level navigation the items of the second level navigation appear and stay visible.

A dynamic navigation only appears when you hover over it with the mouse and then disappears again.

There are also combinations of the two on the market.

Static navigation:
The advantage is that after the user has clicked on the first level entry all the second level entries stay visible and the user has always the overview of all the other navigation points in that category. So if you assume that your users wish to browse within that category it is advisable that you give the user the overview.

Dynamic navigation:
The dynamic navigation has the benefit that you have not to give up any screen real estate for placing the navigation so you can full the entire website with content. As long as only one drop down opens it is usually easy to navigate. The user can also “preview” the content of all subnavigation items without clicking on them which can be very convenient. However, as soon as you have several sublevel menus it becomes more difficult to control the navigation with the mouse.

Combination of dynamic and static navigation:
An excellent example for a combination of the two is the website of John Lewis. The drop down navigation is even grouped in categories and after the user has chosen an item a static left hand navigation menu appears with further details.

Navigation Part 2: How many navigation points?

by on 08. Jul, 2008 in Branding

It is very pleasing to hear in many concept workshops – “A maximum of 7 navigation items, correct?”
This truly shows that core elements of usability have made the round and that people are familiar with them.

However, real life is not always that easy. Let’s look at some issues:

The seven point rule:
It is true and has been psychologically proven that the human brain best can recall 7 items and that the brain capacity after that becomes lower. This is certainly true for example shopping lists. However, from this also the rule: No more than 7 navigation items has been deducted.

Is it applicable? Yes and no.

It certainly makes sense to try to reduce navigational points and keep the navigational structure precise and clear.

However, what are some exceptions?

# Familiarity with a different structure in the “real world”:

For example news sites: Users are familiar with the categories of their daily newspaper such as news, entertainment, sports, weather etc. There it is advisable to retain the structure readers are familiar with.

# Simply too much content

Sometimes it also can help to add an additional top level item to avoid that the site will have too many navigational hierarchies.

# Linking to sub-sites

For example yahoo links to many sub-sites from its main portal and offers a link to view all other categories. This is another way to structure a huge amount many companies are following: Showing the main entries to everybody and adding an additional link to view all navigation items.

UK usability market worth more than £200 million by end of 2008

by on 02. Jul, 2008 in Usability

The UK Usability market will grow by an estimated 20% in 2008 to a value of £214 million, according to research published last week by E-consultancy. They write:

The continued growth of this sector is the result of a growing commitment within organisations towards usability and user experience.

E-consultancy’s Head of Research Linus Gregoriadis said: “The growth of this market reflects the on-going buoyancy of the digital sector and the strategic importance of this channel within businesses. The agencies and consultancies profiled in this report continue to report high levels of demand for their services while companies recruit and expand their own in-house teams.”

Gregoriadis added: “A growing desire for more usable websites from public and private organisations is not the only source of growth for the industry. Many usability experts are transferring their skills to non-web activities and are already finding them to be a significant source of income.”

Headline market trends:

-) Increased competition in digital marketing drives investment.
-) Awareness of the importance of usability moves beyond the web.
-) More organisations embrace user-centred design.
-) Accessibility becomes ‘hygiene factor’ rather than separate discipline.
