Project Outcome - Full Graphical Array 128x64 dots
|
The first full page ItactI display was assembled in Germany on 24 February 2005. The unit managed to display for the first time simple refreshable tactile graphics. Several delays were encountered during manufacture and assembly of the unit, but swift redesign by the engineering team meant that the graphical display was presented on time at the final review meeting. First indication of the refresh speed were very encouraging and are almost certainly capable of meeting the target
of less than 10 seconds for a complete refresh. Partial areas of the display can also be refreshed individually
to increase the effective refresh speed. Because the device is refreshed on a row to row basis, it will be
possible for the user to start navigating the screen before it is completely refreshed. |

The consortium has also created new software to aid the use of the new tactile display.
Since the unit creates a totally new market apart from a few small and expensive prototype displays,
none of the existing screen reader software is suitable. The newly developed screen reader software will make
use of the units unique features and can for example portray the layout of individual windows on the display,
which can be activated by using the touch screen coating, easing navigation. There are also zoom functions
and Braille to text options available.
