Dr. Pramod S. Modi ^[2] | Bhavna Pancholi ^[2] | Megha Patel

Abstract: The assistive technology is one of the most basic and important system that helps a persons with a disability to work around his challenges. Various latest developments in assistive technology for visually impaired is explain in this paper. The latest existing technology enables its users to detect and differentiate between objects, navigate, recognize text and provide vibrational and audio feedback to the user. Various techniques are used, such as text-to-speech and speech-to-text translation, natural language processing, image and video processing and recognition, binaural image mapping and various sensors to make a use of technologies. The blind and visually impaired people needs assistance in their day-today life, for navigation, detecting objects, text recognition etc. , Computer vision based assistive device for the blind is promising and efficient technology but still, the area is still a developing one. Various assistive device exist today to assist the blind most of which are still in prototypical stages. Purpose of this paper is to apprise the research and scientific community about the progress of computer vision based assistive technology for blind.
