System and method for smooth pointing of objects during a presentation
First Claim
1. A method for highlighting a portion of a displayed image, the method comprising:
- displaying an image on at least one display platform;
identifying a portion of the displayed image to be highlighted;
determining at least one color in the identified portion of the displayed image;
identifying a contrasting color to the determined color of the identified portion such that a CIE Delta E metric between the contrasting color and the determined color comprises a predetermined size;
identifying a complementary color to the determined color of the identified portion that is 180 degrees opposite the determined color on the hue saturation value hexcone;
identifying a complementary color to the contrasting color of the determined color that is 180 degrees opposite the contrasting color on the hue saturation value hexcone; and
highlighting the identified portion of the displayed image on the display screen using a linear combination of the contrasting color and the determined color and a separate linear combination of the complementary color to the contrasting color and the complementary color to the determined color.

Abstract
A system and method are provided that allows a speaker to provide real-time annotations to one or more displayed images during a presentation. The speaker inputs the annotations my manually identify a portion of the displayed image using an input mechanism such as a touch screen that is in communication with a presentation monitor and a control system that is controlling the presentation. The identified portions are annotated onto the displayed images using a adaptive color that is selected to provide optimum contrast with the existing colors in the displayed image. In addition to providing adaptive, contrasting colors for the annotations, imperfection such as waviness are removed from the identified portions to created corrected portions that are then annotated onto the presentation image. Annotation is accomplished through computer generated graphics or through the use of a motorized, controllable laser pointer.

-
displaying an image on at least one display platform; identifying a portion of the displayed image to be highlighted; determining at least one color in the identified portion of the displayed image; identifying a contrasting color to the determined color of the identified portion such that a CIE Delta E metric between the contrasting color and the determined color comprises a predetermined size; identifying a complementary color to the determined color of the identified portion that is 180 degrees opposite the determined color on the hue saturation value hexcone; identifying a complementary color to the contrasting color of the determined color that is 180 degrees opposite the contrasting color on the hue saturation value hexcone; and highlighting the identified portion of the displayed image on the display screen using a linear combination of the contrasting color and the determined color and a separate linear combination of the complementary color to the contrasting color and the complementary color to the determined color. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)

14. A method for highlighting selected portions of a displayed image, the method comprising:
-
displaying an image on at least one display platform; identifying a portion of the displayed image by manually drawing the line across the displayed image; determining an average color in the displayed image in at least one of the area of the line or an adjacent area to the line; identifying a contrasting color to the average color such that a CIE Delta E metric between the contrasting color and the average color comprises a predetermined size; identifying a complementary color to the average color of the identified portion that is 180 degrees opposite the average color on the hue saturation value hexcone; identifying a complementary color to the contrasting color of the average color that is 180 degrees opposite the contrasting color on the hue saturation value hexcone; correcting undesirable variations in the manually drawn line using a curve smoothing algorithm to create a modified line; and highlighting the identified portion on the display platform by displaying the modified line on the displayed image using a linear combination of the contrasting color and the average color and a separate linear combination of the complementary color to the contrasting color and the complementary color to the average color. - View Dependent Claims (15, 16)

17. A non-transitory computer-readable medium containing a computer-readable code that when read by a computer causes the computer to perform a method for highlighting a portion of a displayed image, the method comprising:
-
displaying an image on at least one display platform; identifying a portion of the displayed image to be highlighted; determining at least one color in the identified portion of the displayed image; identifying a contrasting color to the determined color of the identified portion such that a CIE Delta E metric between the contrasting color and the determined color comprises a predetermined size; identifying a complementary color to the determined color of the identified portion that is 180 degrees opposite the determined color on the hue saturation value hexcone; identifying a complementary color to the contrasting color of the determined color that is 180 degrees opposite the contrasting color on the hue saturation value hexcone; and highlighting the identified portion of the displayed image on the display screen using a linear combination of the contrasting color and the determined color and a separate linear combination of the complementary color to the contrasting color and the complementary color to the determined color. - View Dependent Claims (18, 19, 20)
