HCI Impact On Society

Impact of HCI

Society:

The development of computers has affected our generation as we now use computers/technology in our everyday lives, people who are disabled especially rely on the use of computers to support their general needs and to make sure that they fulfill their live. Forexaple, if an individual can speak they can use a computer that has text-to-voice on it so that it will speak for them and all they need to do is type into the computer what they want the computer to say and the computer will them say it. Also a computer can also be used to translate your native language into another so that you wouldn 't need to learn the language and still understand what they are saying or know what you want to say in the other language. This

For example, if the individual is visually impaired they won’t be able to see the keys on the keyboard or a keypad to enter their pin number for example. Alternative peripherals like a braille keyboard or a voice activated device will allow them to be more independent as they will be able to the device on their own without the assistance of someone else. If an individual has a disability like they have had their arms amputated then they will be unable to use the mouse or the keyboard as they are designed to be used by your hands so an alternative peripheral would be to use a foot mouse and/or voice activated devices. As they have introduced alternative peripherals it means that people with disabilities are now able to use computers (also interact with them) and so that they can assist them so they can be more independent or communicate. Also devices that haves help hospitals and people with heart problems is a pacemaker, rather than having a heart transplant which is very hard to get the hospital will implant a pacemaker to both monitor and to keep your heart beating at a normal rate. Devices are not only to assist disabled and ill people it is also their to save lives and help them live

By having a translator it will overcome the language barriers across the world.

Fundamental Principles of HCI Design

Perception:

Perception refers to how the user sees and also feels while interacting/using a HCI (Human Computer Interface). Perception needs to be considered when designing a GUI as it needs to be suitable for both the client and the target audience. You need to consider it as they need to be able to use and understand it without getting confused. To make a good and easy to understand GUI the designers use colours, patterns and objects.

Colour

One of the most important concepts to consider when designing and developing a HCI is colour. The colours should be easy on the eye so that everyone can use it. They can also include a feature that allows the user to adjust the colour settings if they need to. By allowing the user to change the colours in the interface it will allow them to be able to use it as people with dyslexia and colour diffusion will need to use certain colour so that they are able to use it.
