interactive

A general term that describes the ability of a person to interact with an application by allowing a user to manipulate the outcome of certain events (for instance, filling out a form, requesting a new Web page, taking an online survey, selecting items in an online ad, etc.) within a two-way communications system that supports direct and continual responses.

As opposed to static media (something that stays the same) or television (which is considered a one-way medium), the Internet is interactive in that all computers require input. Some of the more dynamic applications seen on widgets or online video create additional, creative ways for users to interact with computers and handheld devices.
