Abstract

Disclosed is a device that allows a user to sense 2D image by touch. A panel is softened by heat, and a 2D image from a CRT display, scanner, facsimile machine, or other electonic source is transcribed on it. The panel is the hardened by cooling, so that it can be touched with the fingers. This process is repeatable.

Rewritable Relief Device

      Disclosed is a device that allows a user to sense 2D image by
touch.  A panel is softened by heat, and a 2D image from a CRT
display, scanner, facsimile machine, or other electonic source is
transcribed on it.  The panel is the hardened by cooling, so that it
can be touched with the fingers.  This process is repeatable.

The relief panel system is shown in the Figure.

      The part of the panel (marked 1 in the Figure) directly touched
by a person's fingers is made of plastic.  Usually, the plastic panel
is hardened at room temperature, and the unevenness in the panel,
which represents a 2D image, not lost when the panel is touched.

      In order to erase the image and transcribe another, a small
heater like a comb (marked 3 in the Figure) is made to scan the panel
by means of a driving mechanism (marked 2 in the Figure).  The small
heater moves up and down according to preprocessed image data,
creating unevenness in the plastic panel.

The uneven panel is flattened by a heated roller, and can be made
uneven again.  It is thus rewritable.
