Figure 1. LinguaBytes was designed to facilitate communication between children and their caregivers. It does this by generating spaces where they can meet and communicate and by offering materials that enable communication. Four spaces for (inter)action can be identified: two spaces where either the caregivers or the child is in control, and two other spaces where they share control. The child is primarily in control of input, the caregiver of the choice and timing of stories and exercises, and as such of giving structure to the child's linguistic development.
