When Jeff Sparkman draws his cartoon superheroes with coloured pencils, he often has to ask other people to tell him what colour his masked men turned out to be because he's colour blind. Now, a new smart phone application (app) can help him figure out what colours he's using and how the picture looks to most everyone else.
The DanKam app, available for iPhone and Android for $2.99, is an application that turns the vague (模糊的) colours that one percent of the population with colour-blindness see into the "true" colours as everyone else sees them. In America, an estimated 32 million colour-blind Americans—95% are males—can soon have their life improved.
"DanKam takes the stream of data coming in through the phone's camera and changes the colours slightly so they fall within the range that people who are colour-blind see," developed Dan Kaminsky told CNET. He came up with the idea after watching the 2009 film Star Trek with a colour-blind friend.
It was then that he got to know more about colourblindness like its varying types and degrees. A vast majority, for instance, have trouble seeing red or green due to a genetic defect (遗传缺陷), Blue-yellow colourblindness, however, is rarer and develops later in life because of aging, illness or head injuries, etc. He started experimenting with one of the most common representations of points in the RGB colour model. What the DanKam app attempts to do is clean up the colour space of the image or video signal so that colours can be visible to those suffering from viewing problems. "You can adjust the app to fit your needs. There is a range and not everyone who is colour-blind sees things the same," Says Kaminsky.
Sparkman, a copy editor at CNET, tried out the app and was pleased with the result: "It would be useful for dressing for a job interview," he said. But using it for his art is "the most practical application". It worked well on LED and other lights on electronic gadgets (器械), which means Sparkman can now identify the power light on his computer display green.
