Abstract:


  Every day we are surrounded by information which is supplied in many
forms and we might be expected to make important decisions from that
information.  However, it may not be possible for all recipients of the
information to make such necessary and informed decisions.  In this talk
I will focus on the difficulties encountered by those who suffer from
colour-vision deficiencies.  I will provide one mechanism of a potential
solution to information derived from the commonly used pie-chart which
are commonly used by businesses to visually represent (raw) data as
information.  I use the pie-chart creation tutorial provided by MSDN
to highlight how the colour-vision deficient might have difficulties in
interpreting information.  My potential solution is an image processing
software tool called the HCBEenhanced.  HCBEenhanced identifies the actual
pie-chart within an image, which I call the Region of Concern (ROC)
and any legend provided within the image.  HCBEenhanced then inserts a
halo around each segment of the pie-chart, which I call the halo-effect
of segments.  This new pie-chart is then provided as an output file to the
user.  I propose to demonstrate that those suffering from colour-vision
deficiencies, by use of HCBEenhanced, can have significant improvements
in the ability to interpret the information that was intended from the
original pie-chart.
