Patent attributes
A position detector includes a tablet and a position indicator, which includes a coil and configured to continuously transmit a coil-based signal to the tablet as a position signal and to intermittently transmit the coil-based signal to the tablet as a non-positional signal. The tablet is configured to detect a position on its surface pointed to by the position indicator by detecting the continuously-transmitted coil-based signal, and to determine non-positional information regarding the position indicator (e.g., pen pressure, pen ID, etc.) by detecting the intermittently-transmitted coil-based signal. The position indicator further includes position indicator control circuitry configured to control the position indicator to: (i) receive an indicator control signal from the tablet; (ii) based on the received indicator control signal, select one type of non-positional information from among multiple types of non-positional information regarding the position indicator; and (iii) transmit the selected one type of non-positional information to the tablet.
