Data processing system utilizing discrete operating device

A control method for a data processing system, said method comprising the steps of:

• displaying on a display means an interface screen on which images are generated, with each image corresponding to a data processing operation executed in one of a plurality of data layers, and selection of one of which enables a user to execute a corresponding predetermined data operation;
• detecting by a position detecting means within said interface screen a position selected by using a discrete operating device;
• receiving identification data in a receiving means;
• determining whether identification data stored in a storage means is received by said receiving means;
• selecting, on the basis of a determination result of said determining step, one or more of said plurality of data layers;
• and
• executing a data processing operation in a data layer selected in said data layer selecting step, with said data layer in which said data processing operation is executed being determined by a position detected in said position detecting step.

A control program product for a computer for executing the processes of:

• displaying on a display means an interface screen on which images are generated, each image corresponding to a data processing operation executed in one of a plurality of data layers, and selection of one of which enables a user to execute a corresponding predetermined data processing operation;
• detecting by a position detecting means within said interface screen a position selected by using a discrete operating device;
• receiving identification data in a receiving means;
• determining whether identification data stored in a storage means is received by said receiving means;
• selecting, on the basis of a determination result of said determining step, one or more of said plurality of data layers;
• and
• executing a data processing operation in a data layer selected in said data layer selecting process, with said data layer in which said data processing operation is executed being determined by a position detected in said position detecting process.

A computer-readable recording medium that has recorded a control program for causing a computer execute the processes of:

• displaying on a display means an interface screen on which images are generated, each of said images corresponding to a data processing operation executed in one of a plurality of data layers, and selection of one of which enables a execute a corresponding predetermined data processing operation;
• detecting by a position detecting means within said interface screen a position selected by using an operating device;
• receiving identification data in a receiving means;
• determining whether identification data stored in a storage means is received by said receiving means;
• selecting, on the basis of a determination result of said determining process, one or more of said plurality of data layers;
• and
• executing a data processing operation in a data layer selected in said data layer selecting process, with said data layer in which said data processing operation is executed being determined by a position detected in said position detecting process.
