Thai university develops cheap, touchable ink for the blind
A university in Thailand has developed new ink that could make it a lot cheaper for the blind to read.
It is called Touchable Ink, and it has the ability to rise when heated. This way the usual flat row of printed Braille letters become an embossed version that can be read with fingers. The new technology has been developed in association with Samsung, who supplied the printers, and advertising agency J Walter Thompson (JWT).
With more research, the ink will be available for use in normal printers. Touchable Ink is likely to bring down the cost of printing Braille text for blind users substantially as now there won't be a need to pay more to emboss it. Also the material used is much cheaper than what is used at the moment.
