PDPT Framework—UML Design of flow diagram. The artefacts collections which belong to the actual user position are copied to PDA buffer firstly. The predicted position and new artefacts collection is used if all artefacts are already loaded to PDA buffer. The definition of the Static or Dynamic area depends on the specific case of artefacts size, area size of where the PDPT framework is equipped.
