INPUT is an associate team between the Loki team at the Inria centre at the University of Lille and the Cheriton School of Computer Science at the University of Waterloo in Canada. It involves Géry Casiez (PI), Mathieu Nancel and Sylvain Malacria for Loki, and Daniel Vogel (co-PI) for the University of Waterloo. It also involves two PhD students and two Master's students, currently being recruited or to be recruited.
The associate team is funded by Inria and the University of Waterloo. It started in March 2024 and will last for 3 years. It follows the International Associate Lab (LAI) Reapp (2019 - 2023) funded by the University of Lille and the University of Waterloo.
The objective of the team is to redesign the input pipeline in interactive systems, from the capture of user motion by a sensor, its filtering, transformation and interpretation by the system, to the production of feedback to the user. Routine tasks such as controlling a system cursor or moving a virtual camera involve continuous visuo-motor control, to which the system has to respond accurately and with minimal latency.
The objective for the first year is to focus on the input filtering and signal processing with the primary goal to create an improved version of the 1€ filter, published by Géry Casiez and Daniel Vogel in 2012, which is widely used in research and industry, and remains the benchmark for filtering noisy signals in interactive systems. Other objectives include further work on latency and transfer functions in interactive systems.
