Given the success of the field study, the braille writing tutor project has now evolved into a fully-fledged TechBridgeWorld project with other students,
faculty, and staff continuing the technical research and development, investigating
business models for its distribution, and exploring other potential partners.
After the initial field study with the Mathru School for the Blind near Bangalore, India the researchers incorporated the feedback from teachers and students at the Mathru School into revised versions of the tutor's hardware and software.
- Based on recommendations from the field study, Ph.D. student Tom Lauwers redesigned the hardware of the braille tutor. Some of the improvements included incorporating buttons representing one large braille cell for early learners, making the stylus wireless, and changing the computer connection to a usb cable.
- Nidhi Kalra developed revisions to the software in collaboration with Robotics master's student Jeremy Stolarz.
- A team of public policy and management graduate students affiliated with
Carnegie Mellon’s Institute for Social Innovation focused on the
potential social entrepreneurship aspects of the project through a course
- Research with the braille tutor also expanded to Carnegie Mellon University's Qatar campus where Computer Science undergraduate student Noura El-Moughny has added Arabic braille tutoring capability to the tutor. Noura received support from the Qatar National Research Fund's
Undergraduate Research Experience Program and was advised by faculty member
M. Bernardine Dias. Noura’s research poster entitled “Assistive Technology for
Writing Braille” was also selected as the Best Poster for Computer Science during the
Qatar campus’ Meeting of the Minds in Spring 2007.
- In the Summer of 2007 Computer
Science undergraduate student Daniel Dewey developed a second version of
the braille tutor software in Pittsburgh. Daniel was supported by the Intel First Year Research Experience grant and was co-advised by faculty member M. Bernardine Dias and Robotics Ph.D. student Tom Stepleton. Tom Stepleton produced a large library for tutor/computer interaction on which future applications can be developed.
- Noura El-Moughny's UREP work led to a senior thesis on "Assistive Technology for Writing Braille" which she completed in Spring 2008 with faculty member M. Bernardine Dias as her advisor. She
recieved Carnegie Mellon's prestigious School of Computer Science Alumni Award for Undergraduate Excellence as a result of her thesis work. Noura gave an update on her work with the braille tutor at the 2008 Meeting of the Minds in Doha and won Best Computer Science Project and Best Poster.
- In Spring 2008, Computer Science undergraduate student Kaleem Rahman performed an independent study to implement the capability for basic mathematical symbols into the braille tutor software.
- In summer 2008, Carnegie Mellon undergraduate students Kaleem Rahman, Aysha Saddique, and Saurabh Sanghvi, along with recent graduate Ermine Teves worked in collaboration with Microsoft Research India and The Mathru School for the Blind near Bangalore. In addition to working with other technology-related projects, their primary objective was to field test the newest version of the braille writing tutor. This experience was possible through a summer internship program at Microsoft Research India facilitated by Carnegie Mellon’s TechBridgeWorld group in collaboration with the Technology Consulting in the Global Community summer program.
- Through the non-profit organization ProjectEDUCATE, the project expanded to a new partnership with the Sefula School for the Visually Impaired in Mongu, Zambia. Faculty M. Bernardine Dias and staff Sarah Belousov and Freddie Dias traveled to Mongu in summer 2008 to meet with the headmaster and teachers at the school to introduce the braille tutor.
- In summer 2009, a team of Carnegie Mellon undergraduate and graduate students participated with TechBridgeWorld's inaugural iSTEP 2009 internship program in Dar es Salaam, Tanzania in collaboration with the University Computing Centre located at the University of Dar es Salaam. The team customized the braille tutor's use for Tanzanian students in partnership with the Uhuru Mchanganyiko School.
- In summer 2010, a team of Carnegie Mellon undergraduate and graduate students participated with TechBridgeWorld's iSTEP 2010 internship program in Chittagong, Bangladesh in collaboration with Asian University for Women. The team focused on extending the braille tutor's use in Chittagong in partnership with the non-governmental organization Young Power in Social Action. The Chittagong School for the Blind also provided feedback on the braille tutor during this summer research work.
- We are currently incorporating feedback from partners in the United States, Qatar, Bangladesh, India, Tanzania and Zambia to make new enhancements to the braille tutor's hardware and software.
