Our Automated Braille Writing Tutor project began in Spring 2006 with the work of Nidhi Kalra and Tom Lauwers who were Ph.D. students in the Robotics Institute at the time. Several Carnegie Mellon faculty members advised the students including M. Bernardine Dias, Manuela Veloso, Jack Mostow and Illah Nourbakhsh. Nidhi and Tom conducted their projects through TechBridgeWorld's V-Unit - an independent study opportunity for graduate students to pursue non-traditional research.
The initial field study was possible through our collaboration with the Mathru School for the Blind near Bangalore, India. Initial tests were also carried out with volunteers from the Visually Impaired Pittsburgh Area Computer Enthusiasts. Nidhi implemented the field study during a 6 week stay at the school in Summer 2006. From the very beginning of the project the researchers considered the context in which the tutor would be utilized. They planned for the tutor to be used in a classroom environment where teachers would be able to assist the students in learning to use the tutor. They set up the tutor's connection to the computer so that it would be as clear as possible for visually-impaired instructors at the school. They designed the hardware based on the traditional slate and stylus used at the school to teach braille. We believe this field study was successful as a direct result of prior research and discussions of the context in which the tutor could be used and the knowledge gained on-site with teachers and students.
The field study explored the feasibility of the tutor in a real educational setting with visually impaired students and teachers. The teachers and students were highly enthusiastic about the project and provided valuable suggestions for future improvements. Nidhi documented her experiences at the Mathru School through a blog.
