Hello friends, it is amazing to tell you that there is yet another invention in the field of technology. But this time, it is a vibrating touch screen phone which can help the visually challenged people. This vibrating touch screen phone can for the Braille characters which will be very useful for the visually challenged people in experiencing the touch screen technology.
The scientists have tried to display the Braille dots on a touch screen phone. This is a great step ahead in the path of displaying the Braille characters on a mobile phone. This vibrating touch screen phone has piezoelectric material built into the touch screen. When an electric signal is applied to it this material vibrates. The Braille letters will be having a two-by-three matrix where each character is represented by different combinations of raised dots and absent dots. A software developed by the scientists is installed which will represent a raised dot and an absent dot as single pulse of vibration and longer vibration respectively.
