Digital interaction: where are we going?
In the framework of the AVI 2018 Conference, the interuniversity center ECONA has organized a thematic workshop on "Digital Interaction: where are we going?". Six contributions from the ECONA members investigate different perspectives around this thematic
Multimodal Observation and Interpretation of Subjects Engaged in Problem Solving
In this paper we present the first results of a pilot experiment in the
capture and interpretation of multimodal signals of human experts engaged in
solving challenging chess problems. Our goal is to investigate the extent to
which observations of eye-gaze, posture, emotion and other physiological
signals can be used to model the cognitive state of subjects, and to explore
the integration of multiple sensor modalities to improve the reliability of
detection of human displays of awareness and emotion. We observed chess players
engaged in problems of increasing difficulty while recording their behavior.
Such recordings can be used to estimate a participant's awareness of the
current situation and to predict ability to respond effectively to challenging
situations. Results show that a multimodal approach is more accurate than a
unimodal one. By combining body posture, visual attention and emotion, the
multimodal approach can reach up to 93% of accuracy when determining player's
chess expertise while unimodal approach reaches 86%. Finally this experiment
validates the use of our equipment as a general and reproducible tool for the
study of participants engaged in screen-based interaction and/or problem
solving
