contributing to the development of a complete
independent prosthetic system. These tools include a
flexible retinal processing model, an automatic
synthesizer to program integrated circuits for retinal
processing, and a system to include binocular and
spatial information in the set of stimuli sent to the
brain.
Unfortunately, it is difficult to provide a detailed
and standardized comparison against other systems
under development. On one hand, these kinds of
systems are specifically designed and fitted to
control a particular implant, so no compatibility
criteria are considered. On the other hand, as
neuroengineering is a young field of research, no
standards for measuring and comparing the
performance of a prosthetic system are available.
Nevertheless, some relevant organizations
involved in blindness and low vision research, as the
ARVO (ARVO, 2007), or the Smith-Kettlewell Eye
Research Institute (SKERI, 2007), are organizing
and conducting specific meetings aiming to arrive to
a standardized set of tests that will be useful to
provide a measurement of the performance of these
implants.
