Abstract: Touch sensitivity is enabled using a touch system that comprises a panel configured to conduct signals along detection lines across a touch surface. A signal processor obtains observed values for the detection lines, and identifies an interaction pattern on the touch surface as a solution to a function that comprises an aggregation of differences, for each detection line, between the observed value and a projected value, which is given by a projection function that defines a functional relation between the interaction pattern and the projected value for each detection line. The signal processor implements a normalization to ensure that the interaction pattern indicates weak touches even in the presence of strong touches.
