it is interesting how they use Ipad to teach orangutans

how to behave in a wild. since they are enclosed in cage, maybe they are giving some virtual scene where they would see and feel like what or how it is to live in the wild. so maybe in the future they would release those orangutans in their natural environment. the orangutans can only stick their fingers out to touch the ipad. as the cage won't allow them to bring out any of their hands which is for safety of the people watching them. so at least they get to learn how to behave in the wild with the use of ipad.
