Reducing Latency by Eliminating Synchrony
Min Hong Yun, Songtao He, Lin Zhong · 2017
Drawing or dragging an object on a mobile device is annoying today because the latency is manifested spatially with an obvious gap between the touch point and the line head or dragged object. This work identifies the multiple synchronization points in the input to display path of modern mobile systems as a major source of latency, contributing about 30 ms to the overall latency.
