iVision-2 - Game-based adaptive therapy for children with cerebral visual impairment (iVision-2)

The overall goal of the current research grant proposal for iVision-2 is to
evaluate the effectiveness of a personalized, adaptive gamified
visuoperceptual therapy program on visuoperceptual capacities and
viewing behaviour of children with CVI. We will combine the knowledge
of the iVision-1 and eye-tracking projects in order to optimize the
automated adaptivity approach and thereafter evaluate the
effectiveness of the therapy program in a randomized controlled trial
(RCT) in children with CVI.
More specifically, the research objectives are
1. To consolidate the individual visuoperceptual profile by evaluating
the added value of eye-tracking measurements:
A. By valuating the concurrent validity of eye-tracking measurements
with visuoperceptual deficits;
B. By quantifying reliability measures of eye-tracking measurements.
2. To optimize the adaptivity approach by using more advanced dynamic
difficulty adjustment methods and machine learning.
3. To evaluate the effectiveness of the automated version of the
gamified visuoperceptual training program
A. on visuoperceptual deficits measured using standardized testing
batteries;
B. on objective measures of eye-movements using eye tracking;
C. on functional vision and quality of life.
4. To evaluate enjoyment an user experience during periods of gameplay;
5. To determine which changes in visuoperceptual functioning and eyemovements
are most predictive for changes in functional vision and
quality of life.
