A group of researchers at Osaka University developed a display in which
the sense of touch, i.e. a 1D “sticky” sensation, can be added to a 2D
visual display. A temperature-sensitive adhesive sheet is mounted on
the display. The sheet is made from a special polymer whose adhesion
(friction) can be changed by controlling the temperature of the display
surface with a computer.

Masashi Kawamura: “This is a very unique application, using adhesion
to create a new sense of touch. Haptics will be the next new layer for
display technologies.”
