In an embodiment, an image is provided to an augmented reality application program. The program detects colors and modifies the image. In particular, the program may analyze an image of a scene provided by a camera of a portable electronic device that may be problematic for color challenged users. It then modifies one or more colors such that a color challenged user viewing the altered image may perceive the scene colors as the colors would be perceived by a non-color challenged user viewing the scene.

Systems and methods for processing data representative of a full color image. Such systems may comprise the steps of assisting a color blind person to indicate portions of an image which to their color-deficient vision are indistinguishable, and altering the image to cause those portions to become distinguisable and identifiable.

The present invention provides a technology called Pulse-Multiline Excitation or PME. This technology provides a novel approach to fluorescence detection with application for high-throughput identification of informative SNPs, which could lead to more accurate diagnosis of inherited disease, better prognosis of risk susceptibilities, or identification of sporadic mutations. The PME technology has two main advantages that significantly increase fluorescence sensitivity: (1) optimal excitation of all fluorophores in the genomic assay and (2) “color-blind” detection, which collects considerably more light than standard wavelength resolved detection. Successful implementation of the PME technology will have broad application for routine usage in clinical diagnostics, forensics, and general sequencing methodologies and will have the capability, flexibility, and portability of targeted sequence variation assays for a large majority of the population.

An apparatus and a method are provided for adjusting real time video to compensate for color blindness. A video system includes a decoder that receives and decodes a video signal into original color signals. A processor receives the original color signals and outputs color signals that are adjusted for compensating for a selected one of a number of precharacterized types of color blindness. A screen receives the adjusted color signals and displays images adjusted from the original to compensate for the selected type of color blindness. The adjusted signals are derived from the original signals by one color gamut adjustment for each type of color blindness. The color gamut adjustments are generated by characterizing at least the known, major color deficiencies, and then generating color gamut transforms to fit more range of actual color contrast within the range of perception of the color blind. Each transform is stored in a memory as a lookup table, and looked up by the processor. Software controls whether any color adjustment is to take place, and if so which one of the available mappings is to be used by showing a sample image for each one of the color transforms.

A sentiment visualization system provides a method for identifying content sentiment visually, and does so in a way that is also relevant to individuals who are colorblind. The system provides multiple visual cues that identify sentiment. In some embodiments, the visualization shows a bar that displays a color gradient. The color gradient is anchored by a positive color on one end and a negative color on the other end. The bar contains a color-neutral notch that represents where the sentiment value lies. The system may also allow a viewing user to reclassify an automatically determined sentiment of an item, such as by dragging a notch or other control on the visual display to a new location. Thus, the sentiment visualization system allows users to quickly sift through a large amount of content and identify high priority items for which a fast response is warranted.
