摘要： A device implements a method of tracking objects on a touch surface of an FTIR based touch-sensitive apparatus. The method repeatedly operates to generate an interaction pattern that indicates local changes in interaction on the touch surface, identify apparent peaks in the interaction pattern, and update existing movement trajectories based on the apparent peaks. An error suppression process is executed at least intermittently in the method to process the apparent peaks and/or the existing movement trajectories to identify implicated trajectories with a potential tracking problem, define two or more movement propositions for each implicated trajectory, and cause an evaluation of the movement propositions in one or more subsequent repetitions of the method. The error suppression process improves tracking by postponing the final decision on how to track the object of the implicated trajectory until more information is available.

摘要： Touch sensitivity is enabled using a touch system that comprises a panel configured to conduct signals, e.g. by TIR, from a plurality of incoupling points to a plurality of outcoupling points, thereby defining detection lines across a touch surface between pairs of incoupling and outcoupling points. A signal processor operates in a repeating sequence of iterations to: calculate change values for the detection lines representative of signal changes between the current and a previous iteration, and operate a reconstruction algorithm on the change values to determine a differential interaction pattern across the touch surface. The signal processor also operates to update a tracking pattern as a function of the differential interaction pattern, and generate a current offset pattern based on the tracking pattern. The offset pattern is generated to represent current touch interaction on the touch surface and is supplied for identification of touches on the surface portion.
