About 250 million people in the world suffer from color vision deficiency (CVD). Contact lenses and glasses with a color filter are available to partially improve the vision of people with CVD. Tinted glasses uniformly change the colors in a user’s field of view (FoV), which can improve the contrast of certain colors while making others hard to identify. On the other hand, an optical see-through head-mounted display (OST-HMD) provides a new alternative by applying a controllable overlay to a user’s FoV. The method of color calibration for people with CVD, such as the Daltonization process, needs to make the calibrated color darker, which has not yet been featured on recent commercial OST-HMDs. We propose a new approach to realize light subtraction on OST-HMDs using a transmissive LCD panel, a prototype system, named ALCC-glasses, to validate and demonstrate the new arriving light chroma controllable augmented reality technology for CVD compensation.

Abstract Color blindness, or color vision deficiency (CVD), is an ocular disease that suppresses the recognition of different colors. Recently, tinted glasses and lenses have been studied as hopeful devices for color blindness correction. In this study, 2D biocompatible and flexible plasmonic lenses were fabricated using polydimethylsiloxane (PDMS) and an innovative, low-cost, and simple design based on the soft nano-lithography method. These lenses were investigated for correction of red-green (deuteranomaly) color blindness. The plasmonic lens proposed herein is based on the plasmonic surface lattice resonance (SLR) phenomenon and offers a good color filter for color blindness correction. The biocompatibility, low cost, and simple fabrication of these contact lenses can offer new insights for applications of color blindness correction.

Continuous Use

Colorblind people or people with a color vision deficiency have to face many challenges in their daily activities. Their disadvantage to perceive colors incorrectly leads to frustration when determining the freshness of fruits and the rawness of meat as well as the problem to distinguish clothes with confusing colors. With the rise of the smartphone, numerous mobile applications are developed to overcome those problems, improving the quality of live. However, smartphones also have some limitations in certain use cases. Especially activities where both hands are needed do not suit well for smartphone applications. Furthermore, there exist tasks in which a continuous use of a smartphone is not possible or even not legally allowed such as driving a car. In recent years, fairly new devices called smart glasses become increasingly popular, which offer great potential for several use cases. One of the most famous representatives of smart glasses is Google Glass, a head-mounted display that is worn like normal eyeglasses produced by Google. This paper introduces an experimental prototype of a Google Glass application for colorblind people or people with a color vision deficiency, called OmniColor and meets the challenge if Google Glass is able to improve the color perception of those people. To show the benefits of OmniColor, an Ishihara color plate test is performed by a group of 14 participants either with, or without the use of OmniColor.

Calibration Approach

Colorimetric calibration computes the necessary color space transformation to map a camera's device-specific color space to a device-independent perceptual color space. Color calibration is most commonly performed by imaging a color rendition chart with a fixed number of color patches with known colorimetric values (e. g., CIE XYZ values). The color space transformation is estimated based on the correspondences between the camera's image and the chart's colors. We present a new approach to colorimetric calibration that does not require explicit color correspondences. Our approach computes a color space transformation by aligning the color distributions of the captured image to the known distribution of a calibration chart containing thousands of colors. We show that a histogram-based colorimetric calibration approach provides results that are onpar with the traditional patch-based method without the need to establish correspondences.
