The pointer device includes an induction coil, a clock generating circuit, and a control circuit. The induction coil converts magnetic energy into electrical potential energy and stores the electrical potential energy in a power storage period, and receives an instruction signal from the electromagnetic coordinate positioning apparatus in an instruction receiving period. The control circuit decodes the instruction signal in the instruction receiving period according to the clock signal after the power storage period. When determining that the instruction signal is one of a plurality of predefined instructions, the control circuit triggers, in a data transmission period, the induction coil to send a data signal corresponding to the instruction signal to the electromagnetic coordinate positioning apparatus according to the clock signal after the instruction receiving period. The instruction signal and the data signal each include a fixed quantity of bits."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pointer device","description":"A pointer device is provided.
