Researchers at Wakayama University in Japan have developed a system which can change the tone, contrast, and color of printed materials with the use of a camera and a projector. The researchers are hoping that the system can be helpful to people who suffer from vision impairments like color blindness and low vision.
The system works by tracking and shining a light onto the materials. Using a camera and a projector, the system manipulates the colors of the printed materials by making them more vivid. For example, blue light is projected on the blue colors, and red light on the red colors.
The system can also change the tone and contrast of the images, and even adjust the brightness of the images or turn them into monochrome.
The system can track the colors on the materials, so it can still do its manipulation of the images even if the materials are moved around.
The researchers believe the system can be applied to augmenting vision. To help those with color blindness, the system can adjust the tones to make the colors pop out. To help those with low vision, the system can emphasize the outlines of an image to make facial expressions more distinguishable.
The researchers also tested their system on 3D objects and are currently looking for potential partnerships with businesses who are interested in the technology.
