 AOI scene description
 =====================
 
-An [AOI3DScene](../../../argaze/#argaze.AreaOfInterest.AOI3DScene) is built from a 3D model with all AOI as 3D planes and loaded through OBJ file format. 
+## 2D description
+
+An AOI scene can be described in 2D dimension using an [AOI2DScene](../../../argaze/#argaze.AreaOfInterest.AOI2DScene) from a dictionary description.
+
+``` dict
+{
+	"tracking": [[672.0, 54.0], [1632.0, 54.0], [1632.0, 540.0], [672.0, 540.0]],
