LightSight: A dice to meet the eyes

Abstract

This paper introduces LightSight, a new interactive toy for children with cerebral visual impairment (CVI). Since affected children face different challenges in their perception and processing of information, it is important to provide them with appropriate tools to train their vision skills and related competencies. To address this need, we designed a tangible and illuminated dice, which wirelessly communicates with a game running on a tablet (dice and game together form LightSight). This concept should provide a playful way for the children to train their vision and a range of related motor and cognitive skills (e.g. manipulating the device with their hands, learning shapes etc.). Understanding this interactive toy is simple enough for children who are below the age of 6 years. The paper concludes by discussing the system's design motivations and observations from field deployments.
