REDUCING CONTROL RESPONSE LATENCY WITH DEFINED CROSS-CONTROL BEHAVIOR

摘要

A system for processing user input with reduced control response latency includes an input device, an input processing unit, a high-latency subsystem, a low-latency subsystem, input processing unit software for generating signals, and an output device. The low-latency subsystem receives the signals and generates low-latency output and the high-latency subsystem processes the signals and generates high-latency output. In an embodiment, the signals comprise an identification of a defined cross-control behavior.

1. A system for processing user input, comprising:
display comprising a visualization of a user interface; user input device comprising at least one selected from the group consisting of touch input and pen input, the user input device adapted to output signals corresponding to user input; input processing system operatively connected to the user input device, the input processing system adapted to receive the signals corresponding to user input and to emit signals corresponding to the received signals; first graphical processing and output system comprising software running in a software stack, the first graphical processing and output system adapted to receive at least some of the emitted signals and to generate high-latency data that can affect the visualization of the user interface on the display and to output the high-latency data for use by the display in response to the at least some of the emitted signals; second graphical processing and output system implemented at least partially in hardware, the second graphical processing and output system adapted to substantially simultaneously receive at least some of the emitted signals and to generate low-latency data that can affect the visualization of the user interface on the display and to output the generated low-latency data for use by the display in response to the at least some of the emitted signals; wherein the at least some of the emitted signals received by the second graphical processing and output system comprise an identification of a cross-control behavior, the second graphical processing and output system comprises hardware configured to implement the cross-control behavior, and the generated low-latency data comprises data reflecting the cross-control behavior; wherein, with respect to the response to the at least some of the emitted signals, the second graphical processing and output system is adapted to output the generated low-latency data with low latency relative to the output of the high-latency data by the first graphical processing and output system; and the display being configured to display at least some of the low-latency data and at least some of the high-latency data on the visualization of the user interface.
