The 12 rules of Web usability and interface ergonomics

The 12 rules of Web usability and interface ergonomicsKnow your visitors or users and their habits is an essential point for the architecture of the information in your website. It is the organization of information by different groups or themes for easy access and research and give immediate access.

Visual organization

This is how your site is built: we must have consistency and clarity in the layout and can identify at a glance the different pavers or blocks that make up the site and their features. Indeed, an animation in the body of an item will create a distraction for the user: try to the best of separate areas and to assign roles for each of them.

Consistency

It is to have a well-organized and stable space that is homogeneous throughout the visit of the user.A railway is a navigational guide that will show the visitor its position in the site. Items such as menus, buttons or contacts other important elements should not change location. It should help your visitors to find quickly what they are looking.

Innovate or create must not conflict with the ergonomics. Even if a button must remain a button so that your visitor quickly understands that a click on this element will trigger an action, the graphics change it must absolutely remain readily identifiable and not leave room for doubt.

Conventions

The use of internet has created among users and automatic reflex when visiting a website that should not be upset. Indeed, this change will impact directly your visitor who is now in a learning phase, so unpleasant as it can no longer use his achievements and his previous experiences.

Compliance with these conventions gives your visitor autonomy and ease in navigation and makes the experience more enjoyable.

Few examples :

  • Do not call your home page “instead” (vocabulary conventions)
  • Your logo should be on the top left (location agreements)
  • A link must transform the mouse cursor in hand (interaction and presentation conventions)

Information

The site must be able to react to the actions of visitors and inform. While your visitors is properly informed at the right time with the right means.

Comprehension

Words and symbols chosen must adequately fulfill their role and must be comprehensible. The user-oriented language use is very important when you are targeting the general public. The use of overly technical words or phrases or jokes that only you understand the meaning do not help your visitors.

Assistance

The assistance is guide your users according to their needs and expectations at a specific time. This assistance may be presented in different forms:

  • Explicit assistance as text
  • Visual aid through general organization
  • Help through the affordances or identifying actionable items

Error management

Allow from the design of your website error handling your visitor might encounter. Many mistakes can be avoided through captions or labels of the fields. Many errors are made when filling a form.There must be assistance and explicit and precise answer site informing visitors of his error and in guiding the action to be done to correct it.

Speed

The site should be designed to facilitate the visits of users by helping them to go as fast as possible to find the information sought. Keep in mind that your visitors do not all have the same experience.The implementation of several systems to access the same content can be a good way if it is well designed and can help experienced visitors to go faster. The search engine should offer several levels of searching, simple and advanced for example. Also, avoid unnecessary repetitive action or message.

Freedom

The user should always have a sense of control environment. Basic controls are not to be changed or blocked, such as copy and paste or backtracking browser. Making active user on your site is to give him access and choice to undertake a number of actions, for example, stop animation, lower the volume, prevent if the site is to launch an external application.

Accessibility

The site should be designed for maximum accessibility and, ideally, it must respect the conventions established by the WAI (Web Accessibility Initiative).

The accessibility of a website can be physical: compliance with standard navigation for users with visual impairments.

Technology: the absence or disable some plug-in should not prevent the site from working.

Visual: by adapting the content to the resolution for optimal use.

Your user satisfaction

The satisfaction of your visitor passes through its global experience on your website. A number of parameters and criteria are required to satisfy your visitor, utility requirements, design and graphics, quality of service, etc.
