1. A stylus for entering data on to an entry pad, said stylus comprising:
- a body comprising a housing;
a reference element comprising two distinct portions;
a first portion seated within said housing; and
a second portion comprising a tip, the tip having a bottom end that is at least hemispherical, a reference point in a center of the bottom end of the second portion being used to evaluate a distance d between the reference point and the entry pad;
a damper forming a cladding around at least one part of said reference element, comprising an external wall, called an external wall of said damper, which acts as a variator of the distance d between the reference point and the entry pad in response to a change in pressure exerted on the stylus.

9. A method for measuring a pressure exerted during the entry of data by a user, entered on a writing surface of a pad via a stylus, the stylus comprising a reference element comprising two distinct portions:
-
a first portion seated within a housing; and a second portion comprising a tip, the tip having a bottom end that is at least hemispherical, a reference point in a center of the bottom end of the second portion being used to evaluate a distance d between the reference point and the pad, wherein the method comprises; acquisition, by said writing surface, at at least one instant of the entry, of at least one piece of data representing the distance d of the reference point of said stylus relative to said pad, in a zone of proximity of said pad; and computing pressure exerted on said pad taking account of said distance d.

10. A non-transitory computer-readable memory comprising a computer program product stored thereon, which comprises program code instructions for executing a method for measuring a pressure exerted during the entry of data by a user, entered on a writing surface of a pad via a stylus, when the instructions are executed on a computer, wherein the stylus comprises a reference element comprising two distinct portions:
-
a first portion seated within a housing; and a second portion comprising a tip, the tip having a bottom end that is at least hemispherical, a reference point in a center of the bottom end of the second portion being used to evaluate a distance d between the reference point and the pad, and wherein the method comprises; acquisition, by said writing surface, at at least one instant of the entry, of at least one piece of data representing the distance d of the reference point of said stylus relative to said pad, in a zone of proximity of said pad; and computing pressure exerted on said pad taking account of said distance d.
