ABSTRACT:
An iterative method for calculating and positioning a rectangular balloon containing information in an interactive environment with sensitive areas. A balloon is positioned near, but not overlapping, the sensitive areas of a display screen and is sized based on the amount information to be displayed in the balloon. Each balloon has a body and a tip extending towards the sensitive area. The balloon's position and size is calculated by first initializing the balloon to a preferred variant. If the body does not fit entirely on the screen, a new tip orientation and body is selected while maintaining a golden ratio of height and width. In addition, a new body and tip orientation is selected that displays the largest amount of information if the body does not entirely fit on the display screen.
