Adaptive contextual filtering based on observer colorblindness characteristics
First Claim
Patent Images
1. A method implemented by a computing system having a processor for selectively applying graphical filtering to a character, the method comprising:
- accessing a character to be rendered;
identifying a limited portion of the character consisting of a particular typographical characteristic;
identifying an observer characteristic which identifies whether the observer has dichromatic vision;
selecting at least one filter designed to compensate for dichromatic vision;
applying the at least one filter to at least the limited portion of the character, and applying one or more other filters to one or more other typographical characteristics while refraining from applying at least one of the other filters to the entire character of the accessed character; and
displaying the character after applying the filters to the character.

Abstract
Selectively applying graphical filtering to characters can include the identification of observer characteristics and characteristics associated with different portions of the character. Corresponding filters can then be identified and selectively applied to the characters and, in some instances, without applying the filter to the entire character.

accessing a character to be rendered; identifying a limited portion of the character consisting of a particular typographical characteristic; identifying an observer characteristic which identifies whether the observer has dichromatic vision; selecting at least one filter designed to compensate for dichromatic vision; applying the at least one filter to at least the limited portion of the character, and applying one or more other filters to one or more other typographical characteristics while refraining from applying at least one of the other filters to the entire character of the accessed character; and displaying the character after applying the filters to the character. - View Dependent Claims (2, 3, 4)

5. A computer storage device comprising computer executable instructions that, when executed by one or more processors of a computing system, cause the computing system to implement the following method:
-
accessing a character to be rendered; identifying a limited portion of the character consisting of less than the entire character and being defined by a particular typographical characteristic, the particular typographical characteristic comprising one of either a serif, a stroke, a stem, a diagonal or other distinguishable characteristic that comprises less than the entire character, identifying the limited portion of the character requiring distinguishing between said serif, stroke, stem, diagonal or other distinguishable characteristic and determining whether the limited portion is either the serif, the stroke, the stem, the diagonal or the other distinguishable characteristic; identifying an observer characteristic which identifies whether the observer has dichromatic vision; selecting at least one filter designed to compensate for dichromatic vision; selecting at least one other filter that has been pre-specified for a particular typographical characteristic; and applying the at least one filter to at least the limited portion of the character, and applying one or more other filters to one or more other typographical characteristics of the character while refraining from applying the other filters to the entire character, and the other filters being applied depending on whether the particular characteristic is distinguished to be said serif, stroke, stem, diagonal, or other distinguishable characteristic. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
