A tactile display device includes: a touch plate with a touch surface, a
network of taxels formed in solid parts of the touch plate or in solid
parts of a sub-plate that forms part of the touch plate with each taxel
made up of a strip that can be in at least two states, with the change
from one state to another indirectly or directly modifying the tactile
sensation, and a mechanism for modifying the state of the taxel strips in
a selective manner, including for addressing and for modifying the
taxels' tactile sensation. Each taxel strip has a spiral shape, bordered
on either side by a gap in the form of a spiral.
