Interface Design.
How do you design an interface which is not only easy to use, works well across various devices and screensizes - and is aesthetically appealing as well?
Like a key to open a lock, your UI needs to give access to the
content without bothering the user with the complexities which might
lie beneath :)
The commonly uttered phrase
“good design is invisible” applies perfectly to the design
of interfaces. If no one notices your site menu and happily browses
the site, your design works. You have achieved your goal of a
user-friendly and accessible navigation.
Before you fall into the usual pattern of doing what’s popular – it will serve you well to consider all aspects of the interface to be designed — and once in testing, ask the right question to review the proposed design.

who / what / how
Planning for the approach to interface design:
- who will be using it? – your target group Remember that it is not you, or your client, but the end user who is to guide the approach to interface.
- what is their motivation and goal? – user journey Keep in mind whether your interface is purely navigational or features more involved functions (like sign-ups etc).
- how will they be accessing it? – device / connection / app Plan well to avoid complications during testing. Test early and frequently.
asking the right questions
Only testing and observation will yield the right result:
- how easy is it to complete the task in hand? Do your users navigate with ease? Or pause and hesitate?
- how efficient is the process? Do your users complete the task smoothly? Or does the involved process take too long?
- how well are confirmations/errors handled? Does your user understand and navigate errors easily? Or is the error handling likely to prompt user to abandon the process?
- is using your interface a pleasure or pain? Are you users happy when using your interface? Or do they frown and feel frustrated?
Good design is thorough down to the last detail.
Nothing must be arbitrary or left to chance. Care and accuracy in the design process show respect towards the user.

good principles for UI design
-
Respect your users
A successful interface design will leave the user in control and aim to ease interactive processes by good feedback ('reactions' to interactions via visual means). -
Clarity + simplicity
Above all, a good interface will be clear to understand and intuitively/easy to use. Strive for recognition over recall. -
Consistency
Key to accessibility, usability and UX — clear patterns should be established for familiarity and ease of use. Integrity of both content (tone) and visual language will ensure an effective experience of the interface. -
Low cognitive load
Cognitive load is how much mental energy it takes to use an interface. Ideally, your users will barely notice your design and simply use it. This often mentioned phrase comes to mind: Good design is invisible.
Good design is as little design as possible.

interface considerations
Your work on interfaces will come in various shapes and sizes – you might start from scratch, work on a relatively small project – or be tasked with revising an existing system. Brad Frost’s article interface inventory highlights how vital consistency is for a successful UI design and how an inventory can help the process of a redesign.

interface inventory
Your task is to create an interface inventory of a site of your choosing. Capture the UI elements of the site via screenshots and collect them into categories.
The goal is to study your selected site’s UI design and check on consistency of all aspects such as wording and phrasing for microcopy as much as spacing, typesetting and colour of interactive elements.
This exercise should be a useful trial of how you might approach the UI design on your final major project’s website :)
