摘要： An apparatus is operated to determine the location of at least one object on a touch surface (4) of a light transmissive panel (1). In the apparatus, an illumination arrangement (2, 10) generates a first set of sheets (C1-C3) of light and introduces the first set of sheets (C1-C3) via a first elongate incoupling site on the panel (1) such that the first set of sheets (C1-C3) propagate by internal reflection between the touch surface (4) and an opposite surface. At least two sheets in the first set of sheets (C1-C3) are introduced so as to overlap in a portion of the touch surface (4) such that the object interacts with the at least two sheets. Typically, each sheet (C1-C3) in the first set is essentially collimated in the plane of the panel (1) along a respective main direction. A detection arrangement (12, 14) couples the first set of sheets (C1-C3) out of the panel (1) at a first elongate outcoupling site on the panel (1) and generates output signals indicative of the energy of each sheet (C1-C3) at a set of spatial points within the first outcoupling site. A data processor is connected to identify, in the output signals, attenuation peaks caused by the touching object(s) and to determine the location of the object(s) based on the identified attenuation peaks.

摘要： An apparatus is operated to determine the location of at least one object on a touch surface of a light transmissive panel. In the apparatus, an illumination arrangement introduces radiation into the panel for propagation by internal reflection between the touch surface and the opposite surface, so as to generate a grid of intersecting radiation paths in a sensing area, and a detection arrangement measures the transmitted energy in the radiation paths. A data processor then determines, based on the transmitted energy, the location based on an attenuation of two or more radiation paths caused by the object touching the touch surface within the sensing area. In the apparatus, the illumination arrangement generates at least a subset of the radiation paths by sweeping at least one beam of radiation along the touch surface. The detection arrangement comprises a fixed re-directing device which receives and re-directs the beam onto a common detection point while the beam is swept along the touch surface, and a radiation detector which is located at the common detection point to measure the energy of the beam(s).

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： 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 touch-sensitive apparatus comprises a panel configured to conduct signals from a plurality of peripheral incoupling points to a plurality of peripheral outcoupling points. Actual detection lines are defined between pairs of incoupling and outcoupling points to extend across a surface portion of the panel. The signals may be in the form of light, and objects touching the surface portion may affect the light via frustrated total internal reflection (FTIR). A signal generator is coupled to the incoupling points to generate the signals, and a signal detector is coupled to the outcoupling points to generate an output signal. A data processor operates on the output signal to enable identification of touching objects. The output signal is processed (40) to generate a set of data samples, which are indicative of detected energy for at least a subset of the actual detection lines. The set of data samples is processed (42) to generate a set of matched samples, which are indicative of estimated detected energy for fictitious detection lines that have a location on the surface portion that matches a standard geometry for tomographic reconstruction. The set of matched samples is processed (44, 46) by tomographic reconstruction to generate data indicative of a distribution of an energy-related parameter within at least part of the surface portion.

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.

摘要： A touch-sensing apparatus is based on frustrated total internal reflection (FTIR). The apparatus comprises a panel, in which sheets of light are propagated by internal reflection between a touch surface and an opposite surface. A light sensor arrangement is optically connected to the panel to measure transmitted light energy on detection lines across the touch surface. Each detection line represents a light path across the touch surface from a light source to a light sensor. An object that touches the touch surface will frustrate the propagating light and cause a local attenuation among the detection lines. A data processor is connected to the light sensor arrangement and configured to execute a process for extracting touch-related data.
