Introduction In this assignment I will be addressing the development of HCI’s such as how it started off in the early years and I will be using some resources from the internet to back up my work. I will be describing developments such as extended command line editor (CLE), graphical user interface (GUI), web user interface (WUI) and visual systems such as modern applications software. P1- Describing the impact of HCI on Society, the Economy and Culture The historic development in the early years Command line editor(CLE)- This was used back in the days which was in the first generation of commercial household PC’s, however they were only used by the users who understood the concept of coding. In the early stage of technology CLE wasn’t that friendly with its users because there weren’t any graphical user interfaces available back in the early days, this means that users had to use their own knowledge on how to operate PC devices. Graphical user interface(GUI)- When this was first officially released into PC’s which was a long time ago therefore GUI was very basic and simple back then as technology was developing in the early years. The only users who had some kind of technical knowledge knew how GUI worked as it’s quite confusing to work with therefore if you don’t know what you’re doing then you won’t be able to operate it.

This means not everybody could use GUI as they are not familiar with the interface which means back in the early years there was less computers being sold due to the lack of knowledge. Later on, as time went by companies started to realise and make much bigger and better Graphical user interfaces (GUI’s) so they let the users to use them in a much more easier way. GUI has massively improved compared to about 15-20 years ago as they are a lot more easier to use nowadays. An example to prove my point can be backed up by Microsoft Word as the software has made quality improvements over the years such as making the software faster, secure, making changing in their designs, layouts and many more.

When the software was first realised back in 1983 it was very simple and basic compared to now. The software was able to allow the users to type which was the most common needed feature and still is. However, back in 1983 Microsoft Word if you had a modern device then you were able to share your work with other which could be through online mail as long as you had internet, the users were also able to change the font, writing colour and a few more options. There are still some people who use older versions of Microsoft Word as they are used to that particular version and feel comfortable using, also another reason for using the older versions such as Microsoft Word 2003 would be because there is less features therefore users don’t get confused. I personally think some elder’s users might be still using the older versions as they are quite basic and simple for them. Web user interface(WUI)- The webpages are still the same as in layout wise compared to few years ago and this is because there can’t be many changes in the looks of a design no matter how much you change it. The main feature in most websites is the search bar which is on the top right corner along with many other features such as help and sign in.

Another example of a feature on a website page is the navigation bar which are used to guide the user, so they can go on the correct option on the site such as homepage, contact page and store or it can be anything. The user must make sure that the navigation bar is big enough and fully visible to the people who are visiting your website otherwise mostly elderly people will find it hard to see it therefore they will just go onto a different site as they don’t want to waste their time. Finally, If the user makes all the webpages similar such as using same background and other layouts on their website then it will help people find the other options they are looking for more easily.
