Hello all,
We are hosting Prof. Géry Casiez in our next HCI meeting on Tuesday, November 27, 2018, at 12:30 pm at DGP Seminar room. Details about the talk are below. Lunch will be provided during the meeting.
Title: The measure and compensation of latency in touch and mouse-based systems Abstract: Any interactive system exhibits some delay between a user’s action and the corresponding system response, known as the end-to-end latency. Users can perceive touchscreen latency as low as 2 ms and performance degrades above 25 ms. In indirect interaction, it has been shown that latencies above 50 ms affect performance. Yet, the latency of current systems is above these thresholds of perception and performance. How can we simply measure the latency of current touch systems and mouse-based interfaces to know how performance is affected? How can we determine where it comes from to try to reduce it? Can we compensate some of the latency using trajectory prediction without introducing side-effects caused by next-point prediction techniques?
Bio: Géry Casiez is a Professor of Computer Science at the University of Lille (Science and Technology) and member of Inria Lille. In 2018, he has been appointed junior member of the Institut Universitaire de France for 5 years. His research interests include input devices and interaction techniques, transfer functions, system responsiveness, and hardware fabrication. He is the co-author of more than 30 papers published at CHI and UIST and he regularly serves in the program committees of these conferences. Géry Casiez was president of the Association Franco-phone de l’Interaction Homme-Machine (AFIHM) from 2014 to 2017. He received his Ph.D. degree at the University of Lille in 2004.
