Seamless Visual Sharing with Colour Blind People


Abstract/Technology Overview

Approximately 250 million people suffer from colour vision deficiency (CVD). There exist methods that help colorblind people to distinguish colours via changing the colours in the original images/videos. It is, however, not practical in sharing scenarios where there are both CVD and normal vision audience. Making use of stereoscopic display which offers users two visual experiences (with and without wearing stereoscopic glasses), we propose the very first system that allows CVD and normal-vision audiences to share the same visual content simultaneously.

The company aims to enhance the capabilities of the human eye with technology to achieve richer visual experiences for viewers and strive to become a world-class visual solution provider. Currently, we focus on the use of Binocular Visual and Color Blind enhancement, the software solution to enhance visual experiences and optical capabilities for the TV, medical and military industries.


Technology Features, Specifications and Advantages

Our technology utilises Binocular Single Vision to enhance visual experiences:

  • Making use of stereoscopic display which offers users two visual experiences (with and without wearing stereoscopic glasses), we propose the very first system that allows CVD and normal-vision audiences to share the same visual content simultaneously
  • Colour blind audiences wearing stereoscopic glasses will be able to distinguish the originally indistinguishable colours when presented with computer synthesised binocular images. When normal-vision audiences (without stereoscopic glasses) view the monocular images, there is visually no difference from the original image

Our technology enlarges the dynamic range of images and videos, to allow for this capability in visual perception.


Potential Applications

The technology can be applied in all 3D visual display devices, such as home TVs, movie theaters, mobile screens and virtual reality headsets. It can also be applied to all 3D digital content. The software can also be tailor made for specific industries, particularly visual enhancements for the TV industry and colour blindness rectification for the medical industry.
