Both sell for under $3,000-certainly not cheap, but less than the price of any other braille printer. This article reviews the Porta-Thiel, sold by Sighted Electronics, and Freedom Scientific's Braille Blazer.
A further challenge of our work is to make a map opportunely modified to "speak" for itself, without using dedicated devices, through web technologies and the possibility of easily developing programs for Android-based mobile devices.Braille embossers are known for their bulk and high price tags. Given the difficulty of rendering all the information available in a generic map in a tactile and/or text (Braille) format, the challenge is to provide additional substantial information content through different means: speech synthesizer, text or sound alerts and vibration events that the user may call as needed. The work described herein investigates multimodality, focusing on the tactile interaction skills of a blind subject. Several studies offer interesting solutions currently only available as prototypes. The attempt to convert all the information to an alternative modality allowing satisfactory exploration by blind people is a very active field of research. Geographical maps are by their nature inherently inaccessible to blind users since the information is conveyed mainly in a visual way.
Then each character stored in the text file will be converted to the respective braille format using ASCII values and then converted text will be embossed using the braille embosser, which will make the content available for the blind community. Initially, we will extract the text from a text image and save the text file using different image processing techniques.
In this project, the user will have to upload an image of blinds reading interest, which is to be converted in the braille format. Therefore, braille embosser will help to make available the maximum content of their reading interest in the braille format at an affordable cost. Visually impaired people have some content available in the braille format that they can read but not all content of their reading interest is available in the braille format.
Visually impaired people have to deal with various challenges since they cannot see anything with their eyes and even some visually impaired people are not able to read the content of their interest so they fail to gain knowledge from reading as much as a normal person can obtain.
