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.
