16. Forms

Forms are the most popular way for an user to supply information.

Forms can be very simple for example a single input box with a label and a submit button,

or they can be very complicated with many choices and data entries to be made, for example using a form to apply for a job online you can see many of the standard interface controls we have covered in this mini-web.

A good form design should

• be easy to understand
• be very clear as to the information being requested
• provide plenty of feedback and information to the user
• use appropriate interface control for the type of information being requested
• validate data efficiently to reduce errors
