Methods and apparatus for enhancing color vision and quantifying color interpretation

Abstract

In one embodiment, a method is disclosed that includes selecting a first color sample within a target area in a first image of a first object displayed by a display device; selecting a second color sample within a target area in a second image of a second object displayed in the display device; comparing the first color sample against the second color sample to determine a measure of color difference or a measure of color equivalence between the first color sample of the first object and the second color sample of the second object; and displaying the results of the comparison to a user in the display device. One or more of these functions may be performed with a processor.

         47 . A method comprising:
 selecting a first color sample within a first target area in a first image of a first object, the first color sample being a color of a reagent test pad;   selecting a plurality of color samples within a second target area in a second image of a second object, the plurality of color samples being configured to enable interpretation of a urinalysis, wherein the first color sample is illuminated in lighting conditions different from lighting conditions of the plurality of color samples;   with at least one processor, using an inverse transform matrix to compare the first color sample against the plurality of color samples to determine at least one of a measure of color difference or a measure of color equivalence between the first color sample of the first object and the plurality of color samples of the second object, wherein the inverse transformation matrix links the plurality of color samples under first lighting conditions to corresponding color samples under second lighting conditions; and   using results of the comparing to interpret the urinalysis by determining analyte level in a biological fluid being tested.   
     
     
         48 . The method of  claim 47 , wherein
 the display device is a part of a head-mounted display device.   
     
     
         49 . The method of  claim 47 , wherein the results displayed to the user in the display device include
 the first color sample, a first color name and first color values associated with the first color sample;   the second color sample, a second color name and second color values associated with the second color sample; and   difference color values to indicate the measure of color difference between the first color sample and the second color sample.   
     
     
         50 . The method of  claim 47 , wherein the results displayed to the user in the display device include
 the first color sample, a first color name and first color values associated with the first color sample;   the second color sample, a second color name and second color values associated with the second color sample; and   equivalence color values to indicate the measure of color equivalence between the first color sample and the second color sample.   
     
     
         51 . A method comprising:
 selecting a first color sample under a target in a first image of a first object displayed in a display device;   selecting a plurality of color samples having a plurality of different colors as a selected set of colors;   with a processor, comparing color of the first color sample against the plurality of different colors of the selected set of colors to determine a closest match color sample of color in the selected set of colors and measure a color difference between the color of the first color sample and the color of the closest match color sample; and   displaying the results of the color comparison to a user in the display device.   
     
     
         52 . The method of  claim 51 , wherein the display device is a part of a head-mounted display device. 
     
     
         53 . The method of  claim 51 , wherein the results displayed to the user in the display device include
 the first color sample, a first color name and first color values associated with the first color sample;   the plurality of color samples including the closest match color sample;   a second color name and second RGB color values associated with the closest match color sample; and   difference RGB color values to indicate the difference in color between the first color sample and the closest match color sample.   
     
     
         54 . The method of  claim 53 , wherein the results displayed to the user in the display device include
 an emphasis device to emphasize the closest match color sample in the plurality of color samples.   
     
     
         55 . The method of  claim 54 , wherein
 the emphasis device is one of a color ring around the closest match color sample or a bulls eye around the closest match color sample.   
     
     
         56 . An apparatus comprising:
 a display device in a head-mounted display device displaying
 a color comparison results window including 
 a first color sample within a target area of a first object, 
 a second color sample within a target area of a second object, 
 first and second color names associated with the first and second color samples, 
 first and second color values associated with the first and second color samples, and 
 difference color values to indicate the difference in color between the first color sample and the second color sample. 
   
     
     
         57 . The apparatus of  claim 56 , wherein the display device in the head-mounted display device further displays
 a first color selection window including   a target,   
       the first object under the target, and
 user interface text informing the user regarding the selection of the first color sample within the target area of the first object. 
 
     
     
         58 . The apparatus of  claim 57 , wherein the display device in the head-mounted display device further displays
 a second color selection window including   the target,
 the second object under the target, and 
   user interface text informing the user regarding the selection of the second color sample within the target area of the second object.   
     
     
         59 . The apparatus of  claim 58 , wherein
 the target is a sight of a bulls-eye or a cross-hair.   
     
     
         60 . The apparatus of  claim 58 , wherein
 the first object is a reagent dipstick, and   the second object is reference color chart.
