This page provides additional material to our UIST 2015 paper (PDF).

Our method consists in positioning an unmodified optical mouse on the screen while displaying and translating a particular texture to fake mouse displacements resulting in controlled mouse events. The method works with most optical mice and allows accurate and real time latency measures up to 5 times per second.
