Ode to a Skinned Interface Design
I went to the link my friend sent me,
And I saw what I never had seen;
An ad banner was built in the midst,
Where I used to click on the screen.

With no choice but to scroll down I did frown,
My friend’s interface design was upside down,
Like a tourist with no clue I looked around lost in town,
‘Cause there were no breadcrumbs to be found.

A millisecond too long I located local navigation,
Thinking ‘they sure could use a wireframe tool for their creations’.
With findability resolved these usability problems would dissolve
And, in tow, his search engine ranking would evolve.

What is memorability?

Memorability, in the context of user interface design and usability, refers to the degree of an interface design’s ability to be re-used by users without them having to re-learn the system all over again. The learnability of an interface design refers to the ease of use of learning to use a system for the very first time. But will users remember how to complete tasks after a gap of days, weeks or even months? The time it takes to re-learn a system or correct mistakes from incorrect use directly diminishes productivity, not to speak of the user’s motivation. This is where an interface design has to be maximized for memorability to ensure that it is easy for users to get back into the swing of things as quickly as possible.

Why is memorability important in the context of user interface design?

As neuroscience does indeed improve, it is now known that not using certain brain functions can lead to parts of the brain that handle those functions atrophying. In other words if we don’t use the cells often enough we can loose them. So it is with the navigation of interface designs. Each interface design takes some time to get used to and operate productively. Every time a user has forgotten how to use an interface, time is wasted and/or errors occur. If your interface design has poor memorability then users may even stop using it once they return to it and find that they can’t use it expediently anymore.

What to consider when designing for memorability of an interface design

There could be an inordinate number of reasons why a user could use an interface design wrongly. The key here is that learning and memory function best when the basics of the system are intuitive. Users learn and remember an interface design based on intuition of how to use the tools given to them. Yet, intuitive interface designs can be challenging to create because, after all, people are different. What can be intuitive for one group of people may not be for another group! One has to consider the target user of an interface design to make proper decisions. Is it an interface design for a tool aimed at computer scientists who have high technical proficiency? Is it aimed at consumers without intricate IT know-how? Is it aimed at young teenagers? This is where industry conventions are your best friend. If every word processing tool uses copy paste by clicking on Ctrl + C then that should be a standard you stick with when creating an interface design for such a tool. Another crucial thing to ensure is that users of different proficiency levels can use an interface design. Systems need to be designed to keep the basics intuitive with room for more complex operations to be performed as users become more experienced.

According to Nielsen, the “critical failing of user interviews is that you’re asking people to either remember past use or speculate on future use of a system.” Interviews rely heavily on what people can remember (which is tied to the concept of memorability).  Thus, the main critical failings of users are:

•    Human memory is fallible: Humans can’t remember details about how they used a website and tend to make up stories to rationalize their loss of memory by either embellishing what they do remember or disclosing tentative or false information about what they don’t remember.
•    Users are pragmatic and concrete: Since users usually have no idea how to speculate about how they would use a system based on its description alone.  Users can use what is in front of them but not guess about how they would use an interface design that they have not been exposed to.

The main problem with interviews is that one cannot reliably collect concrete information about the specifics of a user interface design.

What interviews tell you and how you can use them

The main benefit of interview is, according to Nielsen, “exploring general attitudes”.  Interviews are a good way to understand the big picture related to an interface design, but not always the best way to measure details and specifics.  With that in mind, if you are going to use interviews as a method of collecting user experience feedback then use them in tandem with a usability testing method that is more precise or quantitative and allows you to get a better reading on the detail-based problems with your design.

What is findability?

Findability, in computer science, refers to a user’s ability to identify and then navigate the interface designs of websites or web-apps. It encompasses aspects of information architecture, user interface design, accessibility and search engine optimization. The term findability is credited to Peter Morville who remarked that “findability precedes usability. In the alphabet and on the Web. You can’t use what you can’t find.” In this vein findability is two-pronged, on one hand dealing with users finding a website. On the other hand it deals with how users find things that they are looking for, such as the help section or contact details etc., on a given website. According to Neilson Online currently there are more than 1,733,993,741 internet users generating and interacting with vast streams of data. Findability helps ensure your website doesn’t get lost in the mix and, when found, not to be deserted by frustrated users who in all likelihood won’t return, barring a thorough reworking of the interface design.
If you are developing a website with a new user interface and are interested in optimizing your website’s ability to be located by prospective users on the internet, then it is important to infuse your design process with adequate research about the above mentioned topics.

Issues affecting findability on a website
Findability concerns itself with the effort to make a user interface design easily navigable or usable and to ensure that the interface design process is fully integrated and effective. Key to findability is the organization and representation of a user interface design.  This refers to among others, the layout, the use of breadcrumbs and local navigation. Are users able to easily navigate a website and find the services they were looking for? If they found themselves in the middle of a website (which happens often as people share direct links) would they be able to figure out where in the hierarchy they were?  These issues can easily be revolved by adhering to web standards and through iterative usability testing of wireframe prototypes created with the use of wireframe tools such as pidoco. Another important issue affecting findability is the qualities of your web-site’s content and how it is geared towards search engine optimization.

Further changes to the Images interface include the way Google allows users to view selected pictures. Users can now click on the desired image and it will be blown up with the website of origin shown as faded in the background.  Google will also be phasing out text ads and replacing them with image ads to further improve the usability and clarity of its interface design.

OnLive is a new service that seeks to turn the gaming world upside down with a decidedly disruptive Web 2.0 approach. Thus far video games have been largely an affair of hardware, localized at that. You (which usually meant mum or dad) would buy a game console or a PC with the best possible graphics card etc… Once that business was out of the way all that was left was to buy the games. This meant buying a piece of plastic with data on it. With the advent of ubiquitous internet, downloading games directly to your local hard drive became possible through services such as Steam. However one needed compatible hardware to be able to run the software. OnLive’s premise is to harness the cloud and a web-browser for gaming. The games run on servers in a remote data center and the audiovisual output is streamed to your computer in exchange for your controller inputs. This means that as long as you have a good internet connection, the hardware settings of your computer do not matter. All very nice so far.

Competing in this setting, the new Safari boasts some great interface design features that increase the usability of the browser considerably. Safari borrows heavily from iTunes’ interface design even going as far as replicating Cover Flow and thus allowing users to view bookmarks and history visually as they would a photo album or album covers. Top Sites allows users to see their most visited websites at a glance in a cinematic interface design showing previews of the sites. These features of Safari’s new interface design lead to great usability. A photo preview of a website is recognised much more intuitively and faster than a list of URLs. Safari also scores usability points for its Full History Search which allows users to search for webpages using words or phrases from a website they visited, rendering it obsolete to remember complex URLs.

What has changed in the interface design?

Perhaps the most notable change to WizeHive’s interface design is that the new interface design is now much more streamlined, thus saving users time when they work with WizeHive, which may potentially bring down costs.  As before the interface design displays recent activity within an activity stream like Twitter, but now up to five workspaces can be added to clickable tabs at the top of the screen for easy access in addition to a ‘More Workspaces’ tab to access other workspaces that are not displayed by an individual tab within the interface design. There are further little improvements that all seem to add to the usability and clarity of the program.
