Abstract

A first computing device is provided for interacting with an input device across a network The computing device includes processors configured to run an executable, acquire device information, determine network latency, determine a data buffer queue size, provide the data buffer queue size to a second computing device, request device data from the second computing device, acquire data from the second computing device, and provide that data to the executable.
