Error Reduction

Intuitiveness

The user interface should help to reduce the number of errors made when entering data.

This can be done through:

  • Easy to use interface
  • Implement validation/verification checks
  • Input masks
  • Clear warning messages

A user interface should be understood and used without significant training.

This can be achieved through:

  • Easy-to-use interface
  • Match the paper based forms
  • Match the interface of previous systems

Accessibility

The user interface should be accessible to people with disabilities.

Ways to do this include:

  • Clear and simple interface
  • Navigation can be done with keyboard
  • High contrast colour scheme
  • Non-colour cues used
  • Support changing of font size, etc.

Functionality

The interface should allow certain actions to be performed (such as specific queries).

The interface should be:

  • Clear as to how to perform certain functionality
  • Results should be presented in a form that is useful
