Unit 23: Human Computer Interaction
Transcript of Unit 23: Human Computer Interaction
This section investigates the development in HCI within the time period of 20 years.One of the most recognized is GUI (Graphical User Interface) which is used within PC's. GUI stands for graphical user interface. A GUI makes a program easier for the user. GUI is a program interface that makes data transfer from one place to the other easy and simple.
One of the earliest designs of GUI was produced in the 1960s by Ivan Sutherland.He also created a computer graphics program called sketchpad, which he was inspired and carried out research based on how humans learns.
Extended Command Line Editor (CLE)
Before GUIs,there was only one way users could interact with the computer this was by entering a code into the operating system of the computer. From entering the code users were able to create a structure like renaming or moving files.
Web User Interface WUI
The WUI would produce a web page which will allow the user to use and input or retrieve information. One of the most well known programming languages is java script based upon this interface although there are other programming languages.
The amount of developments in software have managed for visual systems to lead to creating 3D pictures for example google maps.3D technology is growing swiftly. There are many movies being produced in 3D for example Sherlock Holmes.
Unit 23: Human Computer Interaction
Describe the Impact of HCI on Society, the economy and culture.
Present and future developments
Interfaces for hostile environments
Productivity per individual
Varied working environment
The ways in which people use computers
Impact in the developing nations
The impact of deskilling work
Psychological and sociological impact of IT
Progression to Human computer interaction have created specific interfaces. The development is for users with visual or hearing problems. Computers have text to speak. For this benefit users who are blind this will enable them to hear the text on screen.
There are future developments which visually improve how realistic the images look on screen. For example computer games or movies. There are also 3D effects which users will be able to experience to make their viewing improve.
Developments nowadays have led to society using computers everyday. In the society we are in most of the population use some sort of computer form every day. For example hospitals, schools, offices etc.
This factor has been developed to help users with sight or speech problems to be able to use computers.For speech impairments the user will speak into a microphone where the computer will transfer it into text. Users will sight issues will
Robots built with remote control features are most efficient this makes the robots "life-saving" in particular occurring events that are to dangerous for humans to participate in. For example bombs, mines or any other explosive devices.
There are simple GUI's but also there are some more advanced GUI's that are more complexed. For example heads-up display which will develop more experience for humans providing more of a virtual experience.
The quick advancements in computers have altered how the economy works.For example the increase in the use of computing has created a much more level of productivity. The use of interfaces are used to help and support employees.
The developments in HCI users will benefit users to be able to use computers and their programs easier than before, using a consistent approach to the features the developers have created.
Users being more familiar with computers have lead to more work being done increasing money as time is money. The constant use has helped employees the respond to commands quicker and easier.
The amount of input from the user will need to be decreased as the amount of customers will decrease as "with every click the user loses interest"
The use of voice input has reduced the amount of jobs available in call centres. Machines are used which has auto messages that connects with the caller.
This has been created in order to help function the brain by providing healthy exercises for the mind, by playing familiar games.
The increase of technology in this generation has provided more equipment for the world of work. For example mobile devices boost communication between further distances.
HCI has helped to create any barriers between cultural communication. Translators can be used to translate words from one language to another.
The use of computers has helped workers throughout their day to day work. This has lead to people working out of the office and in other locations.
The impact on the workers have been decreased as the use of robots have overcome the workers, the amount of work they now receive is minimal
When the amount of work for employees have been produced, this makes them feel unappreciated and unmotivated as their jobs have been taken by machinery.
There has been a number of developments in other countries out of the UK. The use of employees is more valued than machinery.
