Use appropriate response mechanisms. Paper forms have the disadvantage that users can miss, or simply disregard, an instruction. For example, only tick/check one box from a list of 15 or 20 options. In this context interactive forms can be programmed so that the user can only tick/check one (known as a radio button as distinct from check-boxes), or presented with the options in a drop-down menu from which the user can only select one. When designing forms make sure the response mechanism is appropriate to each question.
Users will become frustrated if when you ask for an email address, for example, if the response box only allows for 20 characters. Its similarly annoying to them when its a long free text box, making the customer question whether they are answering correctly and sufficiently. Providing response boxes that reflect the anticipated answer length and format reassures people that they are filling them in correctly.
When implemented well, progressive revealing gives interactive forms a head start over traditional paper forms. When asked a particular question in a form it may be the case that, depending a users response, they are asked a set of specific sub-questions, or alternatively routed to the next appropriate section of the form. In paper forms the specific sub-questions cannot be hidden from the user when they are not relevant to them - but in interactive forms this is relatively easy to do. Use progressive revealing as much as possible in your form design to shield your users from questions they do not need to see.
