An adaptive tracking system for spatial input devices provides real-time tracking of spatial input devices for human-computer interaction in a Spatial Operating Environment. The aggregate data portion has been aggregated from selected data records in a data source system. The N-channel MOSFET is formed a second gate insulating film, a second hafnium layer and a second gate electrode which are stacked on the silicon substrate. The audio data of the audio packs are formatted in a DVD formatting unit with the AMG to be arranged in the ATSs following the AMG. subsequent to installation, manufacture, assembly, sale, etc. The response item may also be returned.
