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.
Use colour strategically. Colour in forms should be used with care - but used well it can really aid form completion and navigation. In general, yellow, for example, is a colour to avoid as much as possible - text set in yellow on a typical light background can be very hard to read - and people can find yellow aggressive.
