Abstract: A low-latency touch sensitive device provides a method for determining a location of a touch event thereon. The touch sensitive device row conductors and column conductors, the path of each of the row conductors crossing the path of each of the column conductors. Each of a set of orthogonal row signals are simultaneously transmitted on a respective one of at least some of the row conductors and an amount of each of the plurality of orthogonal row signals present on each of the plurality of column conductors is detected. A set of orthogonal column signals are simultaneously transmitted on a respective one of at least some of the column conductors. An amount of each of the orthogonal column signals present on each of the plurality of row conductors is detected. The detected amount of each of the plurality of orthogonal row signals and the detected amount of each of the plurality of orthogonal column signals is used to determine the location of a touch event on the device.

Abstract: Methods are disclosed for dynamic assignment of possible channels in a touch sensitive device having rows and columns. In an embodiment, a method determines a first signal space in which to generate signals for use in the touch sensor. Signals are then generated in the first signal space on separate ones of the rows and a column signal is sensed on a column. The first signal space is replaced with a second signal space, and a second plurality of signals is generated for use in the touch sensor in the second frequency space. The second plurality of signals is sensed to identify a touch event in the touch sensitive device.

Abstract: 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.

Abstract: In an embodiment, a touch sensitive device includes a touch interface having conductors and a signal generator for generating signals on the conductors. A touch processor identifies touch on the touch interface by processing touch signals present on the conductors, and outputting a stream of touch events. A decimator receives the stream of touch events and outputs a modified stream of touch events for use by the touch sensitive device, the modified stream of touch events may include predicted or estimated usable touch events.

Abstract: 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.

Abstract: 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.
