This app is about measles symptoms. You are represented in the 3D world as an avatar, walking around in two ways:
-by dragging (the blue and yellow helper circles then assist you by showing the direction and speed of the avatar)
-simply tap on a spot and your avatar will run there. This destination will be marked as a small blue sphere.
On the right there is a slider which enables you to »zoom« in the scene.
There are three objects on the scene telling about the symptoms of the measles. Each is surrounded by two circles. When your avatar stands on the outer circle, the camera focuses on the object under inspection and by walking your avatar on the outer circle you can obseve the object under different angles. When your avatar enters the inner circle, a canvas with a more detailed explanation appears.
