iVision - Development of a Game-based Therapy for Children With Cerebral Visual Impairment
Condition: Visual Perceptual Weakness (Disorder); Cerebral Visual Impairment
MeSH terms: Vision Disorders; Vision, Low
Study type: Observational [Patient Registry]

Summary: 
      The objective of the present study is to develop a therapeutic, adaptive, and enjoyable game
      that will be used by children with CVI between the mental age of 3 and 12 years. Such a game
      will be easy to use and implement by the children, their parents, and therapists.
    

Detailed description: 
      The aim of this project is to develop a novel and adaptive gamified visual perceptual therapy
      platform for children with cerebral visual impairment.

      This is a multi-centered study involving multiple partners, namely KU Leuven, VUB, UGent, and
      a subcontracted game developer. Children and parents will take part during different phases
      of the research project as described in detail in the different phases below.

      Phase I: Quantification of the visual profile (WP1) A quantification of the visual profile of
      children with CVI will be made by KU Leuven. This will be done using the results conducted at
      consultations at the CVI clinic at the Centre For Developmental Disabilities Leuven, Centrum
      Ganspoel, and the CP Reference Centre. A group of 50 children with CVI will be
      retrospectively recruited and results from their perceptual tests will be used to quantify
      their visual profile.

      Phase II: Definition of user and technical requirements (WP1). A definition of user
      requirements for the development of the software and mini-games will be identified based on
      at least two focus groups involving parents and therapists. Two focus groups with
      parents/caretakes and therapists (one for each age group of the children) each lasting
      maximum three hours with a limit of 10 participants.

      There is also a step involving the technical foundations and development of building blocks,
      but this will not involve patients, therefore it is not discussed further (WP2).

      Phase III: Development and validation of the Relative Enjoyment Scale for Primary School
      Children (RES-C;WP1). The development and validation of the Relative Enjoyment Scale for
      Primary School Children (RES-C) instrument will be developed considering not just the
      affective and the cognitive dimensions of RES-C, but also its socio-cultural embeddedness, by
      measuring the child's experience in relation to what they have encountered before their
      experience horizon. The questionnaire will be developed by structured individual interviews
      with 20 children (10 from each age group).

      Phase IV: Initial prototype testing (WP3). During prototype development a game design
      document will be created, specifying what the core gameplay mechanics are, how the game will
      look in terms of art and customizable visuals/gameplay. VUB will use the coded visual
      perceptual profile of the children and map these profiles onto the appropriate game
      difficulty levels for each child. Prototype testing will occur using structured interviews
      with 20 children (10 from each age group) while they play the game.

      The present study will end in October 2020. Phase I, Phase II, and Phase III will be
      completed by October 2019. Phase IV will be completed by October 2020.
