Abstract
A sensor apparatus includes: a linear electrode group extended in parallel; a loop coil group crossing the linear electrode group; and a sensor controller. The sensor controller is configured to sequentially send alternating magnetic fields from the linear electrode group, use the loop coil group to detect an alternating magnetic field generated by an indicator according to the alternating magnetic fields, determine a linear electrode set including part of the linear electrode group based on a result of detecting the a alternating magnetic field, execute a process of generating alternating magnetic fields in at least a part of the linear electrode set for a plurality of times, use a plurality of result values detected by at least the part of the loop coil group as a result of the execution to derive a two-dimensional position of the indicator, and update the linear electrode set according to the two-dimensional position.
