TouchSense for web pages are can even be used in such web elements as Flash or Shockwave animations.

Adding a short duration (0.05) click or pop to a button or menu element is good, especially with buttons or icons that have rollover images or sounds associated with them. Go the extra step and add a different feeling TouchSense effect when the user selects the button or icon too.

TouchSense can be used for more than animations, or user interface elements. Effects can be used to create or enhance mood as well. Use subtle (low magnitude) high frequency "background" hums that ramp up and fade off to create intensity. Use subtle low frequency "background" clicks to create a sense distant machinery or action. These effects do not necessary need to be tied to any specific sound or user action.

In general, you can add effects when interacting with the following items on your web page: images, hyperlinks, areas of image maps.

You can trigger the effects when the following events occur: mouse over, click, and double click.
