A device including an elastic layer that, when depressed by an object, causes a local indentation in the layer, the geometry of the local indentation being in accordance with a force of depression, light emitters, light detectors, a light guide between the emitters and the layer directing light beams from the emitters into the layer at an angle such that the light beams, after entering the layer, remain confined to the layer by total internal reflection, a light guide between the detectors and the layer that directs light beams exiting the layer onto the detectors, each detector having a reference output value corresponding to expected light detection when no object is touching the layer, and a processor determining the object's force of depression based on the geometry of the local indentation in the layer, as calibrated by a deviation between actual and reference output values for one of the detectors.

Touch sensitivity is enabled using a touch system that comprises a panel configured to conduct signals, e.g. by TIR, along detection lines across a touch surface. A signal processor operates to obtain observed values for the detection lines, and identify an interaction pattern on the touch surface as a solution to an optimization 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. The normalization involves computing a respective normalization value for each of the differences as a function of the observed value for the respective detection line; and applying the respective normalization value so as to normalize the respective difference in the optimization function.
