September 9, 2019 Form
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.
Pre-fill where at all possible. If a person has already filled in a form for your organisation they will be frustrated if they have to fill in the same information again. It is difficult for organisations to get their systems to pre-fill known information but when pre-filling is achieved, customers really feel valued.
Progressive revealing, 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.
Also make sure that you make good use of features like running headers and footers on every page to remind people what the form is, where they are, and what page number they are on.
A light shade of a colour, like blue, across the whole background of a form relieves the eye from the harshness of a stark white background. And if the answer spaces people have to fill in are white, the tinted background both cues them in to where they write, and allows them to visually sense how much they have to fill in.
