Disadvantages to GUI
Requires a large amount of memory
* Is relatively processor intensive
* Computing experts may find a GUI slower
than a CLI
Disadvantages to Menu-driven interface
Irritating if there are too many menu screens to
work through – users get annoyed or bored if it
takes too long
* Navigating can be a long process
Advantages to Voice-driven interface
Speech input is much faster than keyboard
input
* No need to learn to type
* Less danger of RSI (repetitive strain injury)
Advantages to Command line interface (CLI)
Quicker to type commands
* Quicker to input commands as shortcut keys
can be used
* Little memory and processing power needed
compared with other interfaces
Advantages to Touch sensitive interface

* No keyboard or mouse is required
Voice-driven interface
voice recognition, can be used to issue

be understood
* Users with a disability that prevents speech
would ne
Disadvantages to Command line interface (CLI)
Very confusing for someone who has never

* Commands have to be typed precisely. If
there is a spelling error the command will fail
* A large number of commands need to be
learned
