I decided gonna write about my volunteer job at Braille Institute.

More than 90% of the world's 161 million blind and visually impaired people live in developing communities . Despite the importance of literacy to employment, social well-being, and health, the literacy rate of this population is estimated at under 3% . In this V-Unit research project, we will develop assistive technology to address this issue. Specifically, we will design, implement, and test an adaptive Braille writing tutor for the Mathru School for the Blind in Bangalore, India.

In developing countries Braille is almost always written with a slate and stylus. Using these tools, Braille is written in reverse, from right to left, so that the page can be read from left to right when it is flipped over. For blind children, learning to write Braille in this manner can be a formidable process. First, children must learn mirror images of all letters, which essentially doubles the alphabet. Second, feedback is delayed until the paper is removed and then flipped over and read, so it may take significantly longer to identify mistakes and correct them. Third, children may not be able to receive the individual attention and guidance needed to learn. Finally, even the paper they use may be expensive or in limited supply.

Inspired by the LISTEN reading tutor , we intend to develop a robust, low-power Braille writing tutor that consists of a digital stylus that interfaces to a computer, PDA, or SimPuter. At its simplest, the tutor uses text to speech software to speak sentences to the student. As the student writes each letter on the stylus, it provides immediate audio feedback by repeating the written letters and words. The tutor will also guide writing and correct mistakes, for example by indicating the correct way to write a letter, by explaining how a letter differs from a similar one, and by choosing exercises that address the particular strengths and weaknesses of a student.

Our goals are to determine the social impacts of such a tutor: Is the tutor feasible in developing communities? How do environmental limitations affect design? Do children or adults benefit more? We also want to understand the technical challenges: Which learning techniques facilitate adaptive responses from the tutor? What types of feedback are more easily provided? To this end, we are working with the Mathru School for Blind Children near Bangalore, India to implement the tutor and study its impact.

This work will be undertaken as part of V-Unit research project. V-Unit is part of the the TechBridgeWorld initiative at Carnegie Mellon University.

You should be clear about what you expect from each of your volunteers. Volunteers deserve to know what you expect from them, as well. To recruit volunteers for a specific role or job, you will need a clear job description from which to develop the advertisements and to show to any potential candidates. Therefore, each volunteer should have a job, or task, description. The description should specify at least whom the volunteer reports ...
