Position detection device and position indicator

A position detection device configured to obtain a position pointed to by a position indicator on a tablet through capacitive coupling between the position indicator and the tablet, the position detection device comprising:

• the tablet, which includes a sensor configured to transmit, through the capacitive coupling to the position indicator, a first control signal and a second control signal for controlling the position indicator, wherein the first control signal and the second control signal are different from each other, and the first control signal causes the position indicator to perform a first control operation and the second control signal causes the position indicator to perform a second control operation different from the first control operation;
• and
• the position indicator, which includes a power source and an electrode, wherein the electrode is configured to transmit, through the capacitive coupling, at least a position-indicating signal to the sensor of the tablet and to receive, through the capacitive coupling, the first control signal and the second control signal transmitted from the sensor of the tablet.
