Abstract

High latency in an interactive system limits its usability. In order to reduce end-to-end latency of such systems, it is necessary to analyze and optimize the latency of individual contributors, such as input devices, applica-tions, or displays. We present a simple tool for measur-ing the latency of USB-connected input devices with sub-millisecond accuracy. The tool, based on a Rasp-berry Pi 2 ...
