Hi Gang,
This week we will have a tea talk by Christopher Pal and Pascal Vincent about their recent vision work. Note the change in time and day. Hope to see you all there.
Date & Time: Friday Sept 9th. 15h30
Place: TBA (likely the LISA lab)
Title: "Monitoring user states during gameplay"
Cameras, microphones, and heart-rate monitors have been installed to
record a player's attitude during Ubisoft gametests. We will describe
the computer vision processing pipeline and various machine learning
approaches that we have so far explored for the sake of analysing the
face-facing camera data. One goal of this work was to allow automatic
detection of interesting events (that is, mainly to detect when the
user's facial expression displays a state other than neutral). This is
achieved with clustering and outlier detection techniques and has been
implemented in a Playtest data browser, which will, among other things,
greatly facilitate any future state/emotion labeling efforts on this
data. We will also give a brief account of the various approaches that
we explored for learning to classifiy facial emotions based on publicly
available labeled datasets. Finally the presentation will open to a
broader reflection on the potential for such technologies to be
incorporated in the future, not only to facilitate playtest analysis,
but also in original live game ideas.
Note: this is a practice for a presentation that will be given at Ubisoft.
Cheers,
Aaron
