Tell me more: Digital eyes to the physical world for early childhood learning

Abstract

Children are inherently curious and rapidly learn a number of things from the physical environments they live in, including rich vocabulary. An effective way of building vocabulary is for the child to actually interact with physical objects in their surroundings and learn in their context [17]. Enabling effective learning from the physical world with digital technologies is, however, challenging. Specifically, a critical technology component for physical-digital interaction is visual recognition. The recognition accuracy provided by state-of-the-art computer vision services is not sufficient for use in Early Childhood Learning (ECL); without high (near 100%) recognition accuracy of objects in context, learners may be presented with wrongly contextualized content and concepts, thereby making the learning solutions ineffective and un-adoptable. In this paper, we present a holistic visual recognition system for ECL physical-digital interaction that improves recognition accuracy levels using (a) domain restriction, (b) multi-modal fusion of contextual information, and (c) semi-automated feedback with different gaming scenarios for right object-tag identification & classifier re-training. We evaluate the system with a group of 12 children in the age group of 3-5 years and show how these new systems can combine existing APIs and techniques in interesting ways to greatly improve accuracies, and hence make such new learning experiences possible.
