Blind and Visually Impaired

In 2001, DTW was approached by Sightsavers International,
a UK- based NGO which works to combat blindness in developing countries, restoring sight through specialist treatment and eye care.  with blind and visually impaired people worldwide. Sightsavers provided the idea for the design of a low-cost Braille writing machine. From this
point DTW began its development of products to aid blind and visually impaired people.




DTW Challenge:

Develop a low-cost Braille machine which could be locally produced in developing countries. In addition, the Brailler had to be easy to maintain and repair.  DTW would also be required to prototype, test, and take the final design through to production, including the making of all required tools, jigs and fixtures.




Project Partners:  

DFID (UK Government's Department for International Development)
British Embassy in Cambodia
Sightsavers International (UK) 
Krousar Thmey (Cambodia) 
Cambodian Association for the Blind


DTW developed five distinctive designs and prototypes.  Testing was carried out in southeast Asia and in Kenya.  The final design the MK5 World Brailler was completed and built in  Cambodia.



DTW Challenge:  Design and produce collapsible guide canes that are low-cost and therefore more  available to blind and visually impaired persons. 

Project Partners:  British Embassy in Cambodia, Cambodian Association for the Blind

Result:  Mobility canes and writing frames were produced comparable to those available internationally but at a much reduced cost.  Production tools were made and local staff trained in their usage.



DTW Challenge:  Develop and produce a Braille writer consisting of a slate and stylus (writing frames)  whereby the stylus is used to push dots through the paper, while the slate serves as a guide – comparable to writing print with a pencil and paper. 

Project Partner:  British Embassy in Cambodia
Result:  Writing frames were produced at a lower cost than those available internationally.
