The EDA PLAY app helps train children's vision and fine motor skills. The options for different image set-ups and task levels enable children with special needs to work with this app. The app was developed in cooperation with low vision specialists and experts in the field of early intervention and care for children with special needs. The app is designed to stimulate the child to watch the action on the tablet display and to complete the tasks in an interactive way. The visual and audio treatment of the app supports the eye-hand coordination. KEY FEATURES - 4 TASK LEVELS and 4 VISUAL LEVELS The app can be customized depending on the child’s individual skills. The visual levels are manifested through the types of illustrations viewed (V1 – V4). The task levels are marked G1 – G4. - SKILLS SECTION The Skills section records the child's progress within the app. Thus, the parents and therapists can monitor the development of the child’s skills over time. - The possibility of the child accidentally switching off the app is prevented. There are sections that can be controlled by the parents (Main menu, Settings, Task overview or Skills section) which are concealed under the buttons located in the corner of the game screen; to enter the menu, these buttons have to be held down for a few seconds. - The WHITE FRAME can be set to distinctively demarcate the work surface of the tablet display. - Upon viewing every task, we hear a spoken word (child’s voice) which explains the instructions in an understandable way. - Designed for children aged 1+ (the easiest level of tasks). - The SIMULATOR OF VISUAL DISORDERS enables adults to better understand how complicated the world is for children with visual disorders.
