摘要： A touch pad is controlled to detect a location of one or more objects (16) on a touch surface (15) of a transmissive element (12). The touch pad includes at least two scanning arrangements (24-26, 28, 29) which are configured as optical scanning transceivers. Each scanning arrangement is adapted to provide a beam of radiation along a pertaining direction (18) in the transmissive element (12), such that the beam propagates inside the transmissive element (12) by total internal reflection. Each scanning arrangement is also adapted to receive radiation from the transmissive element (12) and from the pertaining direction (18), and output corresponding signal. Each scanning arrangement is further adapted to scan the pertaining direction substantially along the touch surface (15). A processing element is arranged to determine, on the basis of the signals from the scanning arrangements, one or more positions on the touch surface (15) where scattering/absorption of radiation occurs as a result of the touching object or objects (16).

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： A device is configured to process data from a touch-sensitive apparatus for the purpose of identifying a reduced performance of components in the apparatus. The apparatus may be an FTIR system that comprises a light transmissive panel, an illumination arrangement for introducing light into the panel, and a light detection arrangement for receiving the light propagating in the panel and for measuring the energy of the received light. The device comprises a processor unit which is configured to obtain a signal comprising a time series of signal values that represent the energy of the light received by the light detection arrangement; calculate a parameter value representing a temporal variability of the signal values in the signal; and identify, based on the parameter value, a reduced performance of any of the illumination arrangement and the light detection arrangement. The temporal variability may be calculated to represent one of an absolute noise level and a signal-to-noise ratio of the signal, and enables the reduced performance to be identified while objects touch the light transmissive panel.

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 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 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 obtains a signal representative of objects on a touch surface of a multi-touch sensing apparatus and executes a method for extracting touch data from the signal. The method operates in a sequence of detection frames. Each detection frame comprises the steps of: obtaining (300) the signal; processing (301) the signal for identifying touches; determining (302) a set of identified touches and touch data for the set of identified touches; and outputting (303) the touch data. At least one of the steps of processing (301) and determining (302) includes a prioritization that actively favors certain touches to be identified and included in the set of identified touches, respectively. Temporal prioritization favors a touch that corresponds to a previous touch, which is identified in one or more preceding detection frames. Spatial prioritization favors a touch that is located within at least one predefined subarea on the touch surface. The and prioritization enables the touch data to be generated in way that is predictable, consistent and in accordance with user expectations within a general or specific context.
