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.

Claims

h) repeating steps d) through g) if the body of the balloon does not fit entirely within the display screen and if not all possible tip orientations have been tried;

i) selecting a body orientation and a tip orientation that displays a largest amount of information on the monitor if the body of the balloon does not fit entirely within the display screen and all possible tip orientations have been tried; and

j) displaying the balloon on the monitor.

5. The method of claim 4 wherein the set of possible tip orientations with respect to the body is:

a) extending from an upper left-side of the body;

b) extending from a lower left-side of the body

c) extending from an upper right-side of the body;

d) extending from a lower right-side of the body;

e) extending a left side of a top of the body;

f) extending a right side of the top of the body;

g) extending from a left side of a bottom of the body; and

h) extending from a right side of the bottom of the body.

6. A method for dimensioning and displaying a balloon near a sensitive area within a display screen of a monitor of a computer system, the balloon having a body for enclosing information and a tip extending from the body towards the sensitive area, the body of the balloon having a first balloon dimension and a second balloon dimension wherein the first balloon dimension is greater than the second balloon dimension, the method comprising the steps of:

a) computing an initial area of the balloon based on a length of the information;

b) initially calculating the second balloon dimension based upon the initial area and a golden ratio, wherein the golden ratio relates the first balloon dimension to the second balloon dimension;

c) initially calculating the first balloon dimension based on the second balloon dimension and the golden ratio;

d) ending calculation of the first and second balloon dimensions if the information is fully visible in a balloon having the first and second balloon dimensions;

e) initializing the balloon having the first and second balloon dimensions to a preferred variant, the preferred variant having a preferred body orientation with respect to the sensitive area and a preferred tip orientation with respect to the body;

f) displaying the balloon on the monitor if the body of the balloon is fully visible within the display screen;

g) selecting a new tip orientation for the balloon from a set of possible tip orientations if the body of the balloon does not fit entirely within the display screen, wherein the new tip orientation has not been previously tried;
