July 18, 2019 Form
People from different cultures have different conventions for answering seemingly innocuous questions like this. Users will become frustrated if when you ask for an email address, for example, if the response box only allows for 20 characters.
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.
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.
Make the form sections visually distinct by setting the section name in bigger and bolder type, and consider including a contents list on the first page or screen to help people navigate their way through the form.
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.
Customise response boxes to reflect required answers and reduce completion errors. If asking for a persons date of birth, it makes sense to provide a box with the exact number of required digits and an example or guidance note to explain the format that the date should be entered in (DD/MM/YYYY).
