A way to read text messages just by touch has been developed by researchers in Germany.
They created a mobile with tiny arrays embedded with moving pins that rise and fall under a person’s fingertips.
This allows a person to perceive a text message as a ‘tactile melody’, said the scientists from Bonn University.
They have shown off a working prototype of the phone at this week’s Hanover industrial trade fair.
The researchers came up with a way to direct the movement of the pins to create specific patterns under the fingers.
