Claim:
1. A method of enabling touch determination based on an output signal from a touch-sensitive apparatus, the touch-sensitive apparatus comprising a plurality of incoupling points configured to emit signals to a plurality of outcoupling points, thereby defining detection lines that extend across a surface portion of a panel between pairs of incoupling and outcoupling points, at least one signal generator coupled to the incoupling points to generate the signals, and at least one signal detector coupled to the outcoupling points to generate the output signal, the output signal being indicative of one or more touches at the surface portion, wherein the method comprises: obtaining the output signal which, if converted into a set of data samples of a given input format, enables a reconstruction algorithm to determine an actual interaction pattern at said surface portion; generating, based on the output signal, a modified set of data samples in said given input format; and operating the reconstruction algorithm on the modified set of data samples so as to determine a modified interaction pattern at said surface portion; wherein
