------------------------------ +Active to Learning Creative discovery in Learning ------------------------------ Our AR tech brings new surprise and unparalleled experience for children, We would like to move forward with “ Exciting feeling” to next stage. Several millions children around the world has barely experienced the contact with wild animals. Many of these children have very basic knowledge about how those wild animals move, reacts and lives: in short not even the "basic literacy". While apps, videos and books exist to create some kind of awareness for those children, they miss the sweet-spot between educational, fun and interactivity. We need an approach which leverages tangible means (such as cards) and high-end technology (such as augmented reality). E-THOLOGY brings you a new experience for learning animals in Augmented Reality. E-THOLOGY enables a child to play with a deck of real cards by finding the right combination of 3 basic items: elements (ground, water, air) along and with an animal and its part (ex: leg) in order to unlock an achievement: AR animation. Children with basic literacy regarding wild animals will broaden their understanding of the world, the issue regarding extinct animals and a purpose to protect and respect Nature. 【Features point】 ・With the scan option (cards) and E-THOLOGY makes great experience. ・Several animals come alive right in front of you! ・Finding right combination and Correct an animal, you can see them in 3D picture book. ・Let's enjoy with parents 【Enabled device: ARkit】 ・iPad:after iPad(5 generation),iPad Pro ・iOS:after iOS12
