Abstract: A device for processing data from a touch sensitive apparatus is provided. The apparatus comprises 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; a light detection arrangement configured to receive the light after propagation in the panel. A processor unit in the device operates to: obtain (S4) a monitored signal which is functionally dependent on transmitted light detected by the light detection arrangement; reconstruct (S5), based on the monitored signal,a two-dimensional attenuation field representing an attenuation of the transmitted light on the touch surface; calculate (S6) an expected monitored signal based on the reconstructed attenuation field;and compare (S7) the expected monitored signal with the monitored signal in order to determine a reduced performance of the apparatus.

Abstract: A touch-sensitive apparatus comprising a panel defining a touch surface; a first set of opposite and essentially parallel rows of components, and a second set of opposite and essentially parallel rows of components. The second set of opposite and parallel rows being essentially orthogonal to the first set of opposite and parallel rows. The components include emitters and detectors, each emitter being operable for propagating an energy beam across the touch surface inside the panel, and each detector being operable for detecting transmitted energy from at least one emitter. Two of the rows of the first and second set are interleaved rows each having an interleaved distribution of emitters and detectors, and the further two rows of the first and second set are base rows each having a distribution of components comprising at least 70% emitters or detectors.

Abstract: A touch-sensitive apparatus is configured to define a touch surface on a panel by propagating diverging energy beams (e.g. of radiation) across the touch surface inside the panel. Two rows (20A, 20B) of components (2, 3) of a first type that emits energy as a diverging beam and a second type that detects energy are functionally connected to the panel at opposite ends of the touch surface. The rows (20A, 20B) are defined by consecutive component blocks (B) that each contain only components (2, 3) of one type and are defined by type and number of included components. Each row (20A, 20B) comprises a respective sequence (S) of two component blocks (B) of different types and is defined by systematically repeating the sequence (S) along the respective opposite end. To achieve an improved spatial resolution of the touch-sensitive apparatus for a given number of components, at least one of the sequences (S) is selected to consist of two component blocks (B) with different number of components, and the sequences (S) are selected such that at least one component block (B) differs between the sequences (S).

Abstract: A signal processor implements a technique for detecting objects on a panel which transmits signals inside the panel such that the objects are allowed to interact with (e.g. attenuate) the signals by contact with a touch surface of the panel. The signal processor operates to define cells that have a given location on the touch surface and are associated with a respective set of intersecting paths for the signals across the touch surface. The signal processor operates to obtain (70) an output signal from a signal detection arrangement that measures a signal property for each path; process (71) the output signal to obtain an interaction value for each path; and determine (73-75) a touch status of a selected cell among the cells by analyzing the distribution of interaction values for at least part of the intersecting paths. The touch status indicates presence or absence of one of the objects in the selected cell.

Abstract: Multi-touch sensitivity is enabled using a touch system that comprises a panel configured to conduct signals, e.g. by FTIR, from a plurality of incoupling points to a plurality of outcoupling points, thereby defining detection lines across the panel between pairs of incoupling and outcoupling points. A signal processor operates in a repeating sequence of iterations to obtain (50) a current signal value for each detection line, and generate (53, 53′) a first interaction pattern and a second interaction pattern as a function of the current signal values, such that the first and second interaction patterns are reconstructed two-dimensional distributions of local interaction with the conducted signals across the surface portion, and represent changes in interaction on different time scales. Thereby, the movement of an object will affect how it is represented in each of the first and second interaction patterns.

Abstract: A touch-sensitive apparatus is configured to propagate energy inside a panel (1) so as to define a grid of transmission paths across a touch surface (4) of the panel (1). The apparatus comprises a first subset of components on a first end of the touch surface (4), and a second subset of components on a second end which is opposite to and parallel with the first end. The components include emitters and detectors, each emitter being operable for propagating a diverging energy beam (e.g. radiation) across the touch surface (4) inside the panel (1), and each detector being operable for detecting transmitted energy from at least two emitters. The components in at least one of the first and second subsets are systematically arranged in spatially separate groups along at least one of the first and second ends, so as to achieve a reduced spacing and/or an increased uniformity of the transmission paths along a center line between the first and second ends compared to an equidistant arrangement of all components.
