Device and support sheet for the punctiform representation of graphical information which may be read by touch

The device as claimed in one of the preceding claims, characterized in that the touch points (2) have an unsymmetrical force distribution, so that it is more difficult for the touch points (2) to be pressed from the activated state into the deactivated state than vice versa.

A support sheet (1) for the punctiform representation of graphical information which can be read by touch, in particular for the representation of Braille script, with a multiplicity of systematically arranged touch points (2), the touch points (2) being formed integrally with the support sheet (1), characterized in that

• the touch points (2) have a touch region (3), which, in the activated state of the touch points (2), protrudes beyond the plane formed by the touch surface of the support sheet (2), and a flexible boundary region (4) between the support sheet (1) and the touch region (3), the boundary region (4) having a lower thickness and/or rigidity than the support sheet (1) and the touch region (3),
• the touch regions (3) are able to spring back and [sic] or below the plane which is formed by the touch surface of the support sheet (1), by means of the associated boundary regions (4), in order to bring the touch points (2) into a deactivated state, and
• the touch regions (3) have an actuating portion, protruding beyond the underside of the support sheet (1) that lies opposite from the touch surface of the support sheet (1).
