Abstract
Provided is an evaluation method for an electronic pen by an evaluation system including a planar sensor and a movement mechanism, the evaluation method including disposing the planar sensor such that a direction of a third axis orthogonal to each of a first axis and a second axis in a three-dimensional machine coordinate system defined for controlling driving of the movement mechanism is orthogonal to a sensor coordinate plane formed by a first axis and a second axis of a two-dimensional sensor coordinate system defined in the planar sensor, performing angle adjustment by causing an orientation of a machine coordinate plane to correspond with an orientation of the sensor coordinate plane by rotating the planar sensor disposed, with a direction normal to the planar sensor being an axis of rotation, and performing position adjustment by causing a sensor reference point to correspond with a machine reference point.
