Abstract
A touch control system and method having an interaction means between a user and a system, at least two transforming means for transforming an excitation of the interaction means into respective signals and a signal processing means configured to determine the position on the interaction means where the excitation occurred. To simplify such a system, the invention uses a signal processing means, which is configured such that signatures are determined based on a comparison of at least one parameter of the respective signals. Also, a touch control system, wherein the transformation means are positioned within a housing with limber sidewalls.

Touch control system comprising:
- a) an interaction means between a user and the system,
- b) at least two transforming means for transforming a mechanical excitation of the interaction means into respective signals, and
- c) a signal processing means configured to determine a signature based on a comparison of at least one parameter of the respective signals, wherein the signature characterizes the position on the interaction means where the excitation occurred.
Touch control system comprising:
- a) an interaction means between a user and the system,
- b) at least two transforming means for transforming a mechanical excitation of the interaction means into respective signals, such transforming means being incorporated in at least one housing with limber sidewalls.
Method for localizing an excitation of an interaction means between a user and a touch control system, comprising:
- a) transforming a mechanical excitation applied on an interaction means into respective signals using at least two transforming means, and
- b) determining a signature based on a comparison of at least one parameter of the respective signals, wherein the signature is a characteristic of the position on the interaction means where the excitation occurred.
A touch control system comprising:
- a) a user interface adapted to receive mechanical excitations;
- b) at least two transducers to transform a mechanical excitation on the user interface into respective electrical signals;
- and
- c) a signal processor configured to determine a signature based on a comparison of at least one parameter of the respective electrical signals, wherein the signature characterizes the position on the user interface at which the mechanical excitation occurred.
