Usability Of UI: Key Aspect For Blooming UX.

https://createbytes.com/insights/

As designers, our main goal within any project is to deliver the best user experience possible in terms of attractiveness (visual and interaction design), serviceability (workflows and information architecture), and effectiveness (features and functionality). In an ideal world, every interface designed and build would have an perfect, easy-to-use workflow, a wisely shaped information architecture, be seamlessly polished down to the last pixel and keyframe, and go through rigorous user testing before being used to production.

If only reality were so kind.

Each day, software teams are faced with judgments that affect the design of the product that they are developing. Changing needs, additional innovation, and restrictions in technology, budget, and deadline will all have an effect on the user’s experience. It’s up to the team to make sure that the impact is a nice one.

A design is not usable or unusable in terms of its features, together with the user, what the user wants to do with it, and the user’s environment in performing tasks, determine its level of usability. A usable interface has three main outcomes:

• It should be simple for the user to become familiar with and capable in using the user interface on the first interaction with the website. If we take a travel agent’s website that a designer has made well, the user should be able to move through the sequence of actions to book a ticket quickly.
• It should be effortless for users to achieve their goal through using the website. If a user has the goal of booking a flight, a good design will guide him/her through the easiest process to purchase that ticket.
• It should be simple to remember the user interface and how to use it on later visits. So, a good design on the travel agent’s site means the user should learn from the first time and book a second ticket just as easily.

This is not the only set of conditions for usability. For example, a usable interface will be comparatively error-free when used.

We can calculate usability throughout the development process, from wireframes to samples to the final deliverable. Analysis can be done with paper and pencil but also remotely when we have better-reliability prototypes.

Visual Factors

The graphic factors that impact the overall user experience are the factors where, normally, you the designer have the most control. That means giving thorough attention to:

• Font Size and Color — Select fonts that are easy to read. That implies high levels of contrast with the background and font sizes big enough for users to read easily. If some of your users are elderly or visually impaired, make fonts larger.
• Layout Colors — Colors need to be stable to convey branding and also to build a visual appeal. In addition, they must provide readability. Often, they need to express hierarchy of information, too.
• Navigation — For users to get the best from a website, they need to get from point A (the entry point) to point B (where they want to be) as quickly and easily as possible. That means offering effective navigation systems, with (for larger websites) search functions, to facilitate that transition.
• Content — The web designer may or may not be responsible for creating the website copy, but there are design elements in the way you display that copy for user experiences:
• Headings — Arrange content into convenient chunks using headings, sub-headings, etc. This means creating a scheme for steady display of each type of heading throughout the website, guaranteeing a consistent experience as users navigate around the site.
• Paragraphs — Make paragraphs clear-cut and easily recognizable to help avoid the user from being exhausted by a “wall of text”. You can also use Gestalt rules to paragraphs to help better illustrate the connections between blocks of content.
