摘要： A device for processing data from a touch sensitive apparatus is provided. The apparatus includes a light transmitting panel with a touch surface and an opposed back surface, an illumination arrangement configured to introduce light into the panel for propagation by internal reflection between the touch surface and the back surface, and a light detection arrangement configured to receive the light after propagation in the panel. A processor unit in the device obtains a monitored signal which is functionally dependent on transmitted light detected by the light detection arrangement; reconstructs, based on the monitored signal, a two-dimensional attenuation field representing an attenuation of the transmitted light on the touch surface; calculates an expected monitored signal based on the reconstructed attenuation field; and compares the expected monitored signal with the monitored signal in order to determine a reduced performance of the apparatus.

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： A video data processing apparatus is provided comprising processing circuitry for performing video processing operations requiring access to video reference frames, and a memory management unit configured to translate virtual addresses into physical addresses. Translation circuitry is provided responsive to a memory access request for reference frame pixel data issued by the processing circuitry to perform a translation process on video reference frame information such that the set of input values for at least one hash function in the memory management unit comprises video reference frame identifier bits contained with the video reference frame information. This approach has been found to reduce the frequency of aliasing in the memory management unit when retrieving video reference frames.

摘要： A multi-touch system includes a panel for conducting signals, e.g. by FTIR, from incoupling points to outcoupling points, to define detection lines across the panel. A signal processor operates in a repeating sequence of iterations to obtain an output signal from a detector coupled to the outcoupling points and generate a formatted signal value for each detection line, and operate a reconstruction algorithm on the formatted signal values to determine an interaction pattern on the panel. The signal processor also, at least intermittently in the sequence of iterations, operates compensation data on the formatted signal values to compensate for contaminations on the panel, and calculates updated compensation data based on an interference pattern determined as a function of the interaction pattern, the interference pattern being a 2D representation of contamination-induced signal interferences. The influence of contaminations in the interaction pattern is thereby suppressed.

摘要： Multi-touch sensitivity is enabled using a touch-sensitive apparatus comprising a panel for conducting signals from a plurality of incoupling points to a plurality of outcoupling points, thereby defining detection lines between pairs of incoupling and outcoupling points. Signal generators coupled to the incoupling points generate the signals, and signal detectors coupled to the outcoupling points generate an output signal indicative of one or more touches on the surface portion. A signal processor obtains the output signal which, if converted into a set of data samples of a given input format, enables a predetermined reconstruction algorithm to determine an interaction pattern on the surface portion. The signal processor generates, based on the output signal, a modified set of data samples in the given input format; and operates the predetermined reconstruction algorithm on the modified set of data samples so as to determine a modified interaction pattern on the surface portion.

摘要： A touch-sensitive apparatus comprises a panel for conducting signals from incoupling points to outcoupling points. Detection lines are defined between pairs of incoupling and outcoupling points. A signal generator is coupled to the incoupling points to generate the signals. A data processor processes the output signal to generate a set of data samples, which are non-uniformly arranged in a two-dimensional sample space. Each data sample is indicative of detected energy on a detection line and is defined by a signal value and first and second dimension values defining the location of the detection line on the surface portion. Adjustment factors are obtained for the data samples, each adjustment factor being representative of the local density of data samples in the sample space. The data samples are processed by tomographic reconstruction, while applying the adjustment factors, to generate a reconstructed distribution of an energy-related parameter within the surface portion.
