“…The fields of engineering and colorimetry have paid special interest to the study of anomalous color vision. Both have worked hand in hand to develop active tools that work by image processing to help these subjects in their daily tasks [6,7]. However, this type of aid, although useful for performing certain tasks, requires the use of displays to artificially increase the contrast perceived by CVD subjects, and depends on the specific task to be facilitated.…”

This paper analyzes, through computational simulations, which spectral filters increase the number of discernible colors (NODC) of subjects with normal color vision, as well as red-green anomalous trichromats and dichromats. The filters are selected from a set of filters in which we have modeled spectral transmittances. With the selected filters we have carried out simulations performed using the spectral reflectances captured either by a hyperspectral camera or by a spectrometer. We have also studied the effects of these filters on color coordinates. Finally, we have simulated the results of two widely used color blindness tests: Ishihara and Farnsworth-Munsell 100 Hue (FM100). In these analyses the selected filters are compared with the commercial filters from EnChroma and VINO companies. The results show that the increase in NODC with the selected filters is not relevant. The simulation results show that none of these chosen filters help color vision deficiency (CVD) subjects to pass the set of color blindness tests studied. These results obtained using standard colorimetry support the hypothesis that the use of color filters does not cause CVDs to have a perception similar to that of a normal observer.

“…With the developments in the smart glasses and other head mounted wearables, the usage of such active optoelectronic glasses in CVD management has been explored by several researchers. [53][54][55][56][57][58][59][60][61][62] Lausegger et al introduced an experimental prototype of a Google Glass application, called Omnicolor, to help people with color deficiency. [53] Google Glass, first manufactured in 2013, is a head mounted wearable device which is priced at $1500.…”

“…Since Epson smart glass is more affordable than the Google Glass, it has become more popular in research fields. [ 61 ] The application developed [ 60 ] improves the image for color blind people by processing the frames from a live video stream, altering the frames containing the indistinguishable colors for the color blind, and finally displaying the processed video. The application focuses on increasing contrast between red and green colors for which it utilizes two processing techniques.…”

Color vision deficiency (CVD) or color blindness is an ocular disorder that hinders the patients from distinguishing shades of certain colors. Color blind patients are often not considered for critical occupations (e.g., military, police) and cannot differentiate colors in public places or media (i.e., watching TV). The most common form of color blindness is red‐green, which is a result of either a missing or defective red or green photoreceptor cone. Since no cure for this disorder exists, sufferers opt for methods to enhance their color perception. The products and methods that have been developed to aid CVD patients are discussed. These technologies include contemporary work on gene therapy, tinted glasses, lenses, optoelectronic glasses, and advanced features developed on smartphones and computers. Among these wearables, tinted glasses, developed by companies such as Enchroma, are the most widely used by CVD patients.

Designers and system analysts have long struggled to extract and repurpose data from user research by laboriously presenting content in the form of storyboards, behavioral-type personas, or journey maps. An alternative is to convey insights from user research through scenario-based personas that represent user research data through storytelling. This provides a more streamlined way to convey data rather than character-based personas; however, scenarios are effortful for developers to articulate and envision. In this work, we empower assistive technology development teams to access authentic user experiences with scenario-based personas through tangible and digital artifacts. Scenario-based personas were used for conveying the results of a user analysis study for color identification mobile applications for people with visual impairments. We developed scenario-based personas for persons with impaired color vision based on the main contexts identified in user research studies. The method combines personas depicted in silhouettes of people with impaired color vision and scenario contexts that capture the place and activities. Silhouettes were used in the artifacts to reduce the bias that a face often generates in persona-based scenarios. Preliminary findings suggest that scenario-based persona tools were effective in describing the stories and context behind why a person with a visual disability would consider a color identification application. Through this method, scenario-based personas were able to foster understanding of the application's target user population by showing their main contexts of using these mobile applications and create playful and tangible artifacts to capture and convey such user information to designers and developers in the Humanistic Co-Design community. Methodological considerations for using scenario-based personas in user research will be discussed.
