Position based identifier combination information processing system, unit, and method

An information processing system comprising:

• a reader that reads out a first identifier present uniquely in a user's body;
• one or more first wireless communication units each having a second identifier, wherein each of the one or more first wireless communication units is fixed to a user's hand directly or indirectly;
• a second wireless communication unit that is not fixed to the user's hand directly or indirectly, wherein the second wireless communication unit that outputs a signal to a predetermined communication region that surrounds at least part of the second wireless communication unit, and each of the one or more first wireless communication units is either within the communication region or outside the communication region, such that a first subset of the one or more first wireless communication units is inside the communication region and a second subset of the one or more first wireless communication units is outside the communication region, and the first subset includes a third subset of at least one of the first wireless communication units and a fourth subset of at least one of the first wireless communication units, wherein the second wireless communication unit reads out only the second identifier from each of the first subset of the one or more first wireless communication units including reading out respective identifiers from each of the first wireless communication units in both the third subset and the fourth subset which are combined with each other;
• and
• an information processing unit that executes processing based on a combination of the first identifier that is read out by the reader with one or more second identifiers from the third and fourth subsets that are read out by the second wireless communication unit from the first subset of the one or more first wireless communication units.

An information processing unit comprising:

• a database, wherein a plurality of first wireless communication units, each fixed to a user's hand directly or indirectly, each have an identifier and a second wireless communication unit that is not fixed to the user's hand directly or indirectly outputs a signal to a predetermined communication region that surrounds at least part of the second wireless communication unit, and each of the plurality of first wireless communication units is either within the communication region or outside the communication region, such that a first subset of the first wireless communication units is inside the communication region and a second subset of the first wireless communication units is outside the communication region, and the first subset includes a third subset of at least one of the first wireless communication units and a fourth subset of at least one of the first wireless communication units, and wherein the database gives a description of a content of processing in accordance with a combination of only a plurality of identifiers assigned one by one to each of the third and fourth subsets of the first wireless communication units;
• and
• an arithmetic section that, when the plurality of identifiers from the third and fourth subsets that are combined are inputted, reads out, from the database, the content of processing in accordance with a combination of the plurality of identifiers from the third and fourth subsets that are inputted, and executes processing in accordance with the content of processing.

• and
• an arithmetic section that, when the first identifier and one or more second identifiers from the third and fourth subsets that are combined are inputted, reads out, from the database, the content of processing in accordance with a combination of the first identifier and the one or more inputted second identifiers from the third and fourth subsets that are inputted, and executes processing in accordance with the content of processing.
