Prototype of learning tool with augmented reality and natural hand interaction using depth sensing camera

Interests in education are growing all over the world and many methods to raise their learning effects have been suggested in the past few years. Especially, when augmented reality is used in the learning process, a learner can manipulate objects in one's perspective in addition to obtaining knowledge that cannot be experienced in the real world or traditional learning environment. In this case, the learner can directly control objects by using one's creativity or keeping up one's learning pace in accordance with the user's abilities, thus aiding one's learning process rather than merely providing fragmentary knowledge. This paper deals with a prototype application of augmented reality which is intended to improve the learning effect by letting users directly interact with augmented content during the learning process.
