Devices, systems and methods are disclosed for processing stylus interactions with a device and drawing the results of those interactions in a manner that reduces noise and latency. This includes selecting a filter based on a velocity of an input, the velocity determined by comparing coordinates and timestamps associated with the input events. A first filter may be determined using previous input events to reduce latency and a second filter may be determined using previous and subsequent input events to improve accuracy of the filter selection. An output may be generated using the first filter and/or the second filter to combine the benefits of the reduced latency and the increased accuracy.
