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： An integrated touch-sensing display is operated to detect the location of one or more objects on a touch surface. The integrated touch-sensing display defines a display area. A light guide (14) is arranged over the display area to define the touch surface (16). The light guide (14) is illuminated internally such that an object (20) contacting the touch surface (16) causes part of the illuminating light to be scattered towards the display area. An array of light sensors (6) is integrated within the display area to detect the scattered light. Based on output signals from the light sensors (6), a processing element obtains image data that represents the light that impinges on the display area excluding ambient light, and determines the location of the object (20) on the touch surface (16). Ambient light may be suppressed by a spectral passband filter in front of each light sensor (6), and/or by electronic filtering of the output signals from the sensors (6). The light guide (14) may be illuminated by invisible light, and may be arranged to cause an illuminating beam to be internally reflected at a peripheral edge surface of the light guide (14), so as to increase the intensity of illuminating light inside the light guide (14).

摘要： An apparatus is operated to determine a location of at least one object on a touch surface of a light transmissive panel. An illumination arrangement in the apparatus is operated to introduce beams of radiation into the panel for propagation by internal reflection between the touch surface and the opposite surface, and to sweep each beam along the touch surface within a sensing area. Thereby, the sensing area is illuminated such that an object that touches the touch surface within the sensing area causes at least two beams to be temporarily attenuated. The illumination arrangement is arranged such that each beam, downstream of the sensing area, is swept along one or more elongate outcoupling sites on the panel. At least one light sensor, which is optically coupled to the outcoupling site, is operated to measure the received energy of the beam within the outcoupling site. A data processor is operated to obtain, from the light sensor, an output signal indicative of the received energy of the beam within the outcoupling site as a function of time, and to identify, based on the output signals for the different beams, the location of the object.

摘要： An apparatus is controlled to detect locations of a plurality of objects on a touch surface of a panel. An input scanner arrangement introduces at least three beams of radiation into the panel for propagation by internal reflection, and sweeps the beams inside the panel across a sensing area, preferably in at least two different principal directions. At least one radiation detector is arranged to receive the beams from the input scanner arrangement while they are swept across the sensing area. A data processor is connected to the radiation detector(s) and operated to identify the locations based on an attenuation of the beams caused by the objects touching the touch surface within the sensing area, the attenuation being identifiable from an output signal of the radiation detector(s). Each output signal may be further processed to generate a transmission signal, by dividing the output signal by a background signal which represents the output signal without any object on the touch surface.

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 device operates on output signals from a light sensor arrangement in a touch-sensing apparatus to determine a position of an object on a touch surface. The apparatus includes a light transmissive panel that defines the touch surface and an opposite surface. A light source arrangement provides sheets of light inside the panel, wherein each sheet comprises light that propagates by internal reflection between the touch surface and the opposite surface from one or more incoupling points to a set of outcoupling points. The light sensor arrangement generates the output signals, which represent light reaching the outcoupling points. The apparatus is configured such that an object touching the touch surface locally attenuates at least two sheets of light. To determine the position, the device identifies, in the output signals, a set of signal profiles originating from said object. The device determines at least part of an attenuated light path across the panel based on each signal profile, and identifies the position of the object on the touch surface based on the thus-determined attenuated light paths. In determining the attenuated light path, the device applies a predetermined width function which is representative of a dependence of signal profile width on distance to the incoupling point due to light scattering caused by at least one of the touch surface and the opposite surface.

摘要： A touch sensing apparatus is controlled to determine the position of one or more objects (7) that interact with a touch surface (1). The apparatus includes a group of emitters (2) arranged to emit light to illuminate at least part of the touch surface (1), a light detector (4) arranged to receive light from the group of emitters (2), and a processing element (7). Each emitter (2) is controlled to transmit a code by way of the emitted light such that the code identifies the respective emitter (2). The codes may at least partly be transmitted concurrently. The codes may be selected such that a value of an autocorrelation of each code is significantly higher than a value of a cross-correlation between any two codes of different emitters (2). The processing element processes an output signal from the light detector (4) to separate the light received from the individual emitters (2) based on the transmitted codes, and to determine the position of the object/objects (7) based on the light received from the individual emitters (2), e.g. using triangulation or image reconstruction such as an algorithm for transmission tomography.
