HCI - Coggle Diagram

- - - - A low resolution monitor can be used with this type of interface
      - This type of interface does not use as much CPU processing time as others
      - A CLI does not require Windows to run
    - - If you mis-type an instruction, it is often necessary to start again
      - For someone who has never used a CLI, it can be very confusing
      - There are a large number of commands which need to be learned
  - - - Disadvantages
        
        Visually impaired people might have trouble seeing the text
        
        Not good for highly complex applications
        
        Only limited options presented
      - Advantages
        
        Little training required
        
        Fast to enter data or to make choices
        
        Easy to program
  - - - Disadvantages
        
        Can only respond to commands that have been programmed
        
        Highly complex to program
        
        Not widely available as other forms of interface are often superior
      - Advantages
        
        More flexibility than a dialogue interface
        
        Suitable for physically handicapped people
        
        The user does not need to be trained
  - - - Disadvantages
        
        Personal preferences
        
        Not suitable for all user tasks
        
        Privacy
      - Advantages
        
        Intuitiveness
        
        Flexibility
        
        Speed
  - - - Disadvantages
        
        The menu can take up a large part of the screen so you have to keep flicking back and forwards
        
        If the menu is poorly designed it might be hard to read
        
        A poorly designed menu interface may be slow to use
      - Advantages
        
        There are no commands to learn
        
        Extremely easy to use
        
        They don't need huge amounts of processing power
  - - - Disadvantages
        
        In direct sunlight it is much less efficient and very difficult to read the screen
        
        You have to be within arms reach of the device
        
        The screen has to be big enough to be able to touch the buttons without missing
      - Advantages
        
        Touchscreen devices usually have more simple user interfaces
        
        Touchscreens are easy to use helping more people get used to using computers
        
        Having less or not buttons means that you can put more effort into having a big screen
  - - - Icons
      - Menus
      - Windows
      - Pointers
    - - GUIs take up a much larger amount of hard disk space than other interfaces
      - They need significantly more memory (RAM) to run than other interface types
      - They use more processing power than other types of interface
    - - You do not have to learn complicated commands
      - You get the benefits of WYSIWYG
      - They let you exchange data between different software applications
- - - - Jungles
      - Extreme weather
      - Mines
  - - - Unable to use a standard keyboard or keyboard
      - Communication difficulties
