Human Computer Interfaces

Human Computer Interfaces

1. Command Line interfaces

   • Must be typed correctly
   • Experienced users who know the command lines work more quicker and efficient
   • They don't need memory and processing power
   • Command driven programs do not always need to run on windows

2. Menu driven interfaces

   • They are easy to use as the user doesn't have to remember sets of commands
   • They are user friendly- you can often guess your way round the menud
   • They can be irritated if there are too many levels of menus to move around

3. Graphical user interfaces

   • They are much easier for beginners
   • They enable you to easily exchange information between software using cut and paste or 'drag and drop'
   • They use a lot of memory and processing power. it can be slower to use than command line
   • They can be irritated to experience users when simple tasks require a number of operations
