Faculty of the Universidade Estadual de Ponta Grossa (UEPG) developed a system capable of recognizing, with the aid of a webcam, 63 signs of tactile reading (Braille). The initiative to create the system, called Litteris came because of the difficulty in transcribing the evidence of vestibular writing the institution applied for the visually impaired.
In just two months, teachers Ariāngelo Hauer Dias, Carlos Vargas Luciano Sant'Ana, Ivo Mathias Mario and Marcelo Bilobrovec, created the program that in just a second, photographs and decodes a letter in Braille to the Roman alphabet.
The system, according to teachers, work for which an artificial neural network, having "taught" to identify the symbols, to translate them. "Each Braille symbol in the database has ten images photographed under different conditions of the same symbol (position and shadow), related to the letter of the alphabet. Therefore, our tests showed 90% of success of the program at the time of reading with a webcam, "he says.
To use the program, the teachers adapted the webcam with a torch to ensure proper lighting of the symbol and a plastic frame that makes the instrument ideal for the distance focus. "The idea was to create a tool that ensures easy handling, low cost and high productivity," says Bilobrovec.
The initiative came from the lack of professionals who understand the period of vestibular Braille. Hauer said that the project account for the 3rd Prize Werner von Siemens Technological Innovation 2008 in category Science and Technology Industry and the method, because it offers solutions for simple application and gains to society. "In the midst of 110 registered projects, we hope, but thought that ganharķamos the prize," he says.
Teachers talk about the intention of making a version online and free program. "The target is popularize our idea, so that anywhere in the country and using the same tools we use, the carrier of visual impairment is easier to communicate and be understood," says Hauer.
