The most common view of interactivity involves “cause and effect” relationships with the user; the user performs an action with some sort of input and as result another action occurs. The following are common examples of some cause and effect levels of interactivity:
- Rollovers – the user rolls their mouse over a certain web-based object and that object responds in a certain way.
- Flash Websites – the user can “interact” in a variety of different ways with the content of the website; the user has a cause and effect relationship with the content on the page.
- Video games – the player can control an on-screen character’s actions though the input of a keyboard or game control.
- Hypertext – the user clicks on a bit of text and as a result is taken to a different location on the web.
- Input Devices (keyboard, mouse etc.) – the most obvious for of interactivity, the user’s actions towards the input objects are directly mirrored in the program the user is using.
