I am trying to develop technology for persons who are both, deaf and
blind, and this seems promising. Does anyone know  Sriram Subramanian
of the U of Bristol? Or anyone else working in the area of tactile
output -- shape changing membranes and the like.

NRI technologist unveils world's first mobile phone that can change
shape on demand

A shape-changing mobile device may sound like a gizmo straight out of
Harry Potter's collection, but thanks to intermingling cutting edge
technologies, it may soon be a reality.

A team led by India-born technologist Sriram Subramanian on Monday
unveiled the world's first mobile phone that can change shape on
demand.

It can take the shape of a gaming console by curling two opposite
edges or it can look like an ATM keypad.

"We are introducing the term 'shape resolution', which adds to the
existing definitions of screen and touch resolution," Subramanian,
professor of computer science at the University of Bristol, said at a
conference on humancomputer interface in Paris.

In a video, the prototype device developed by Subramanian and his
students, including Abhijit Karnik, can be seen taking different
shapes. The flexible device - named Morphee - adapts a new shape on
its own to the context of the use in order to offer better user
experience.
