Abstract
An input system according to one aspect of the present disclosure comprises an electronic pen having a pen tip; and an electronic device configured to detect a pointed position of the electronic pen based on a detection signal received pursuant to an approach by the pen tip toward the electronic device. The electronic device includes: a planar sensor configured to acquire the detection signal; a flexible cover provided above the planar sensor and exposed to the outside; an actuator configured to displace the cover at each of multiple positions in an area defined by the planar sensor in at least a direction normal to the planar sensor; and a drive controller configured to perform drive control of the actuator so as to form local unevenness at a position of the cover corresponding to the pointed position of the electronic pen.
