At one point, access to technology, especially the Internet, was only a dream for the visually disabled. For a long time, online tools were not accessible owing to either the lack of availability or high cost. But today, popular screen reading software applications like Job Access With Speech (JAWS) and open source screen reading software applications like NVDA are available for free. These applications allow a blind person to access a computer and perform several of its functions without the need of a screen!

Accessing the Internet was initially not very easy, but as days passed several modules were added to screen readers, and now, almost 50% of the Internet, especially the text based part, is accessible to the blind. Among the accessible websites, one common roadblock encountered by the visually disabled is the CAPTCHA.

CAPTCHA, Completely Automated Public Turing test to tell Computers and Humans Apart, is a method used to prevent automated programs from accessing secure websites. CAPTCHA normally displays an image, the data in which must be manually entered into another text box to authenticate a human user. Though Google’s RE-CAPTCHA provides an audio alternative, its success rate is less than 50%. I used this several times, and succeeded only once.

Last week we discussed the talking walking stick innovation. Today, I am here with another patent, brought to my attention by the reliable, Naveen. Banking on certain patents to navigate your way through the world, is not an uncommon feature in knowledge driven industries and I embark on a mission to learn a few tricks. This patent, filed in 2008, by Universidade Do Porto, Portugal, seems to be an outcome of Academic Research.

The Guidance, navigation and information system especially adapted for blind or partially sighted people (US 20110172907 A1) patent aims to provide sound sign posts for the blind. The Abstract reads as follows:

Talking Walking Stick – Blind Patents 1

This post was first published on 19th August, 2014.   Every blind person aspires to live a life of independence, a life of freedom and free will, a life free from intrusion, physical and psychological. Some patented inventions have attempted to enhance this very independence, and I will, in my upcoming posts, endeavor to take an unbiased look at some of them. In 1991, Hsieh Chi-Sheng filed a patent for an electronic talking stick for the blind. Before we get into details, one must understand the role of a stick, or cane, in a blind man's life. It is, simply put, the most important tool for...

This post was first published on 15th September, 2014.   In my earlier posts (Post1, Post2, Post3, Post4), we discussed the mobility of a visually disabled person that is directly proportional to his awareness of the environment. The more he knows about his surroundings, the easier it gets for him to move around. An issue in achieving this, is the extent of the person's sensory involvement. Most blind people use auditory signals to understand the state of the environment and a navigation device is better off leaving sound signals alone. The touch is another sense that is extensively used for mobility. Owing to the human...

This post was first published on 4th September, 2014.   A cane, as I had mentioned in one of my earlier posts, is a blind person's lifeline. It allows a person to make his way around by means of touch from a distance. The length of the cane may vary based on a person's height, and on an average, it allows a blind person to feel for objects up to about a distance of 1.2 metres. Traditional canes operate completely on the basis of touch. Owing to the development of sensing technology from deploying infrared rays to lasers, several people have tried to make contactless...
