Applications cannot enlarge a small screen visually, but they can implement techniques that virtually increase the size of the display. One way is providing horizontal or vertical scrolling of the user interface to make new information visible while hiding other content. Another idea is a Peephole display that shows a different portion of a bigger picture when the phone is moved to the left, right, up or down. Unfortunately, neither approach works well with IVVR (Interactive Voice & Video Response). There are no positional sensors usable with 3G-324M, and scrolling requires fast screen updates with the ability to hold a key as long as the user wants to scroll. High delays in the current 3G-324M deployment and lack of transmitting the information that a key is hold for a time prevent the implementation of such features. However, applications can have multiple layers, such as a deck of cards that can be shown or hidden depending on the user
