As the structure and layout of the website is extremely poor, there is virtually no obvious navigation that you would expect in the form of buttons or tabs. This lack of navigation was highlighted by my test users. The only elements that could potentially pass as a basic navigation would be hyperlinks that are linked within the many paragraphs of text. These links direct your browser to a specific area on the page where the required information is. There is also a link at the bottom of the page that returns the user's browser to the top of the page.

As the website is very basic in layout and structure, there are very little affordances associated with it. The only form of interaction the user has with the website is clicking on the links which takes them to various areas of the page. There are no forms that can be filled in or buttons / features that can be interacted with. All the usual browser affordances are still present, such as scrolling bars, which indicate to the user that there is more information to view off the area of the screen.

There are a few constraints that could affect the website including the screen resolution of a user's pc. If the website cannot be displayed on a certain screen resolution, this would affect the users' ability to use the website. The range of colours used could also prove to be a problem, as some screens may not be able to support a full spectrum of colours. This would make the website display differently on different monitors.

Accessibility

Websites have a wide range of users; most importantly websites need to be made accessible for users with disabilities. Over 14% of the UK population is registered disabled. There are many different types of technology that can help with people who have a disability, such as the use of a screen reader or a refreshable Braille display for people with full visual impairment. Users who have partial visual impairment would need to be able to zoom and enlarge the content on a website for easy reading.

The current website has not been produced with disabled users in mind. There are no tags on images, so screen readers would not be able to describe to the user what a certain image was about. When checked with the w3 website validation tool, ATA Electrical returned 235 errors and 4 warnings. This result shows that the HTML content could pose a problem if being read by a screen reader / refreshable Braille display.

Due to the vast amount of monitors available and the higher screen resolutions that users have to choose from, the website needs to be able to look presentable in all different configurations of browsers and monitors. I managed to test the website over 5 different monitors which were using different screen resolutions & also using different browsers. Surprisingly, the website managed to retain its look and was somewhat presentable in all browsers and monitors. This shows that users should not have a problem accessing the website no matter what their software & hardware configuration is.

Content & Presentation
The comments from my test users revealed that the layout and presentation of the ATA Electrical website was very poor. The websites' visual elements have little or no relevance to the accompanying textual content and test users stated that the images are not very appealing.
