Human / Computer Interaction and Usability & Accessibility Impact of Interface Design: Usability is defined as the measure of a potential of a product to accomplish given goals of the user. In the field of information technology, this term is used in relationship to software applications and sites on the internet.

On the other hand, it can be used to refer to any product that is used to accomplish a certain task(Marcus, Aaron, 2011).Product usability is determined by the following tasks: ease-of-use, clear defined process for evolution and virtual consistency.

Usability testing, refers to a process by which the users of the product are asked to perform particular tasks in order to measure the ease-of-use of a product, its task time and the user experience perception. The usability testing can be best used together with user-centered design.

Best practice for websites and services includes the following: the website should be descriptive as this good for search engines and good for visitors to, the number of items on the menu should be limited to seven, it also includes avoiding drop down menus because they can be difficult for search engines to be able to crawl, they can also be annoying at times, the websites should also be in order that gives visitor what they want before they can see what you want (Wentz, Lazar, 2010).

The You Tube search engines is an example of product that can be used by the consumers to access sites or by a developer to replicate a limitation to the consumer.  Its URL is https:www.youtube.com.

This site is used by consumers to post their videos, watch videos and download those videos on the internet. You Tube relates to usability/accessibility because it is easy to use and have an interface that is easily accessible. It has sound prompts that aid the visually impaired and it gives one hint of what you are looking for the moment you start typing.
