Multi-touch and multi-user detecting device

A multi-touch and multi-user detecting device comprising:

• user signal generators which are associated with a plurality of indicators and which, in operation, generate indicator identifying signals;
• a sensor conductor including a plurality of first conductors arranged in a first direction and a plurality of second conductors arranged in a second direction intersecting said first direction;
• a signal transmitting circuit configured to supply determined signals to the plurality of first conductors arranged in said first direction;
• a signal receiving circuit configured to receive reception signals from the plurality of second conductors arranged in said second direction;
• an indication position detecting circuit configured to detect positions indicated by the plurality of indicators on said sensor conductor based on signals that are output from said signal receiving circuit;
• a first indicator identifying information detecting circuit configured to receive the indicator identifying signals, which are generated by the user signal generators and transmitted to said sensor conductor, from said sensor conductor, and to detect indicator identifying information based on the indicator identifying signals, the indicator identifying signals being distinguishable from the determined signals supplied by said signal transmitting circuit to the plurality of first conductors arranged in said first direction;
• and
• a correspondence relation determining circuit configured to determine a correspondence relation that indicates which one of the positions indicated by the plurality of indicators is based on an indication operation performed by which one of the plurality of indicators, based on positional information that is output from the indication position detecting circuit and the indicator identifying information that is output from the first indicator identifying information detecting circuit.
