Development in HCI

It is impressive how fast development in HCI have taken place over the last few years. The Development that is mostly recognised is how most of technology devices are getting smaller and more compact. For example, mobile phone and computer used to be very big but is now much smaller and easier to carry around. 

MS DOS

In the past, there was an operating system called MS DOS which uses CLE (Extended Command Line Editor) system so the only thing that appears on the screen was C:\ prompt. Therefore the only way that the user could interact with the computer is to type in command lines for the computer to function in the way they want (such as moving, renaming, deleting, creating new files and log in to the computer). Nowadays, there are many operating systems that provide the user with GUI (Graphic User Interface) which makes it much easier for the user to access to different programs. Therefore, GUI is one of HCI development that has made a big change to the world because computer is now accessible for almost anyone and not just computer experts who have knowledge of command lines and computer codes.

Macintosh OS

Few years later after introduction of GUI, the thing called WUI (Web User Interface) was invented. It allows interaction between human and computer via web browser and made it much easier for the user to access or input the all kinds of information.

There are also other developments such as 3D images which gives the user this pop out effect and realistic feeling to such images. 3D (stands for three dimensions) has been developed constantly every year since the first 3D film in the 1950s to the successful 3D film like Avatar in 2009.In fact, Sony has now invented 3D television that can be view without the need of E-D glasses (stands for eDimensional. It enabled us to view 3D images more vividly 3D). However, users have to sit perpendicular to the television screen to be able to see the footage in 3D. I believe that this can definitely be further developed into something that we human could gain a lot of benefit and entertainment from.

It is possible for E-D glasses to be developing into 3D contact lenses. 3D contact lenses could become very useful as well as make things easier for the viewer because with these contact lenses, the viewer should be able to turn their head into any angle and still see such footage in 3D. However, the viewer will have to make sure that they take of contact lenses before they driving as it could reduce half of the brightness of incoming light which can be very dangerous if you wear it while driving.

I believe development of 3D could make a huge impact on society as it gives us a great visual experience and because it could give us a great visual experience, it is currently being used to develop virtual reality (that could change our life forever) which we could use for education purpose to improve our productivity. This could also impact the economy as it will definitely create a lot more jobs for people, and because we could use it for education and research purpose to improve out productivity, we will gain more chance to get a good job and good paid. 3D television could also impact culture as it will increase the amount of electronic devices that needs to be recycles. Therefore, there will be more jobs available for people in developing countries (that e-waste take place).

Voice output or speech activate software has also been improve so that it is more accurate and the user no longer have to speck very slowly and make sure that there is a gap between each words they are saying. There are also other developme00nts that could improve usability such as thought input and virtual reality.

Thought input is another development of HCI that I believe could make a big change to us and disable people. Nowadays, it is quite hard to control thought output as the user will have to put in a lot of concentration and think command to a computer. However, I believe that it will soon be develop so that the thought recognition is more accurate and easier to use.
