摘要： In an embodiment, a touch sensitive device includes a touch interface having rows and columns and a signal generator for generating unique orthogonal signals on a plurality of the rows, respectively. A touch processor is identifies touch on the touch interface by processing touch signals present on the columns, and outputting a stream of touch events. A decimator receives the stream of touch events, selectively identifies one or more of the touch events in the stream, and outputs a modified stream of touch events for use by the touch sensitive device.

摘要： A frequency division modulated touch detector having row and column conductors arranged such that the path of the row conductors cross the paths of the column conductors, and signal emitters associated with each row, the emitters being adapted to transmit a signal having a specific frequency and initial phase on each row conductor, and a receiver associated with each column to receive signals present on the column conductor. A signal processor is adapted to determine an in-phase and a quadrature component for each of the transmitted signal found in the received signals, and to project a vector representing the transmitted frequencies at their initial phase onto the respective in-phase and quadrature component to determine a measurement for each transmitted signal on each column, and create a heat map reflecting those measurements, the heat map thus containing data reflective of touch.

摘要： A method and system for distinguishing between sources of simultaneous touch events on a touch sensitive device with row conductors and column conductors, the path of each of the row conductors crossing the path of each of the column conductors. Orthogonal signals are simultaneously transmitted on a respective one of the rows. Each column is processed to determine strength of each of the orthogonal signals present thereon. Simultaneous touch locations are associated with a discrete source based on the presence of body-transmitted cross-talk therebetween, as reflected by the determined signal strength corresponding to the touch locations. Alternatively or additionally, a user-coupled signal generator generating another orthogonal signal provides a user-unique signal to the receivers. The signal strength of the user-unique signal is used to associate one or more touch locations with the user coupled to the user-coupled signal generator.

摘要： A system for processing user input includes an input device, an input processing unit, a high-latency subsystem, a low-latency subsystem, input processing unit software for generating signals in response to user inputs, and an output device. The low-latency subsystem processes signals corresponding to at least some events and generates corresponding programmable low-latency output, the programmable output being based, at least in part, on state information being maintained by the high-latency subsystem. The high-latency subsystem processes signals corresponding to at least some events, and generates corresponding output, the output of the high-latency subsystem being higher latency than the output of the low-latency subsystem with respect to a given event.

摘要： In an embodiment, a touch surface, such as a GUI is graphically divided into two or more input regions, and based on this division, input event paths from a single sensor can be integrated within an operating system to provide application developers with the ability to easily and effectively filter there-between. The graphical division allows an application developer to specify which elements of a given GUI take one path, versus another. In an embodiment, low-latency and high-latency event paths are provided; an algorithm takes into consideration input regions and, based on those regions, handles the low- and high-latency input event paths in a computer system, directing the appropriate inputs through the appropriate processing, and directing the output to the appropriate process or queue without creating constraints on the low-latency event processing due to the presence of higher-latency event paths for a given sensor.

摘要： A system and method are disclosed for using a touch sensing system capable of sensing location of a finger or object above a touch surface to inform a touch response system in an electronic device of a predicted future user input event or motion data in advance of an actual touch event. Current user input is sensed via the touch sensing system and data reflecting hover information is created. A model of user interaction with a touch surface is applied to the data representative of the user input to create data reflecting a prediction of a future user input event. In an embodiment, prior to occurrence of the predicted user input event, a predicted location and a predicted time at which the predicted future user input event will occur are provided to a touch response system.

摘要： Disclosed are systems and methods for decreasing latency between an acquisition of touch data and processing of an associated rendering task in a touch sensitive device having a touch sensing system capable of producing touch data at a touch sampling rate and having a display system that displays frames at a refresh rate. In an embodiment, the system estimates at least one of (a) a period of time for sampling touch data from the touch sensing system, (b) a period of time for computing touch event data from sampled touch data, and (c) a period of time for rendering of a frame to a frame buffer. The system determines a period of time Tc for (a) sampling touch data from the touch sensing system, (b) computing touch event data from sampled touch data, and (c) rendering of a frame to a frame buffer, based at least in part on the estimate. The system determines a point in time Tr at which the display system will be refreshed from the frame buffer. A sampling start time is computed based at least in part upon Tr and Tc. Sampling of the touch sensing system is initiated to obtain sampled touch data at the sampling start time. Touch event data is computed from the sampled touch data, and a frame that reflects the touch event data is rendered to the frame buffer prior to the time Tr. The display is then refreshed from the frame buffer.

摘要： In a low-latency touch-sensitive device, post-processing is performed to convert a two-dimensional map of signal strengths into usable touch events. Four such post-processing procedures are disclosed: field flattening, touch point detection, interpolation and touch point matching between frames. The field flattening procedure subtracts an offset to remove crosstalk between rows and columns, and compensates for differences in amplitude between particular row/column combinations due to attenuation. The touch point detection procedure computes coarse touch points by finding local maxima in the flattened signal. The interpolation procedure computes fine touch points from the coarse touch points. In an embodiment, such interpolation is done by fitting the coarse touch points to a paraboloid. The frame matching procedure matches the calculated touch points to each other across frames.
