Abstract

See full text

A film of a pen input device is provided, and a point determined by a combination of a static friction coefficient value x and a kinetic friction coefficient value y falls within a region including a line segment and the neighborhood of the line segment in a coordinate system showing the static friction coefficient on the X-axis and the kinetic friction coefficient on the Y-axis, the line segment being expressed as
