摘要: The invention relates to a system for recording a track comprising: a utensil comprising a tip and equipped with a magnetic object; a device for locating the magnetic object configured to determine an estimated reference position on a writing surface; and a matrix-array touch sensor configured to define a set of M pixels, among N pixels, at least partially encircling the estimated reference position, and to detect the contact of the tip on the writing surface on the basis of the electrical signals generated by said set of M pixels.
