Optical sensor for teaching color theory to blind students

摘要

The invention is a fully functional optical sensor designed to enable blind students in our art department to identify the different colors and paintings they use when working. The developed prototypes can determine the pigments of RGB and CMY models, as well as some combinations of them, such as vinyl and water-based coatings, whether they are soluble or dry, which is very helpful for learning color theory. The theory defines a set of rules to identify and mix colors, which is essential for visual arts, whether it is painting, painting, film, photography, sculpture, design,Among other things. Technically, in a short period of time, the optical sensor consists of a laser source, a double fiber and a photodetector. The data received by the photodetector is processed, and then the determined wavelength name is reproduced in an audible manner.
