REDUCING LATENCY IN INK RENDERING |
摘要 |
A reduced-latency ink rendering system and method that reduces latency in rendering ink on a display by bypassing at least some layers of the operating system. “Ink” is any input from a user through a touchscreen device using the user's finger or a pen. Moreover, some embodiments of the system and method avoid the operating system and each central-processing unit (CPU) on a computing device when initially rendering the ink by going directly from the digitizer to the display controller. Any correction or additional processing of the rendered ink is performed after the initial rendering of the ink. Embodiments of the system and method address ink-rendering latency in software embodiments, which include techniques to bypass the typical rendering pipeline and quickly render ink on the display, and hardware embodiments, which use hardware and techniques that locally change display pixels. These embodiments can be mixed and matched in any manner. |
