Abstract
A system and method are provided to enable the indication positions of respective indicators (e.g., fingers) to be detected (multiple-point detection) and also to enable detection of the users of the indicators (user detection). Signal generators for generating different signals for respective users are provided, and the signals from the signal generators are supplied to a sensor section through indicators. In a multi-touch and multi-user detecting device 1, a transmitting section 200 supplies determined signals to respective transmitting conductors 11Y. Respective receiving conductors 12X receive the signals from the transmitting conductors 11Y and also the signals from the signal generators of the users. Based on these signals, a user-and-position identifying circuit 33A and a position detecting circuit 34A in a receiving section 300A function to detect indication positions indicated by the respective indicators as well as the users using the indicators.
