*****IUI Dyadic IMPRESSION Recognition Challenge (virtual event)*****



The Dyadic IMPRESSION Recognition Challenge, to be held in March 2022 in conjunction with IUI 2022 in Helsinki, Finland, will be devoted to all aspects of artificial intelligence and behavorial science for the analysis of human-human interaction from multimodal data. 

To advance and motivate the research on human bodily responses in dyadic interactions, we organize the challenge which uses the open and accessible multimodal IMPRESSION dataset. It addresses multimodal recognition as well as dynamic multi-user recognition, where both interlocutors’ information can be exploited.


The challenge aims at automatic impression recognition. This challenge will focus on automatic impression recognition of multiple individuals (i.e., the Receiver, that is, the person who forms an impression of the other, i.e., the Emitter) during a dyadic interaction. Self-reported impressions in the warmth and competence dimensions are given, associated with synchronized face videos, eye movements and physiological signals (including ECG, BVP and GSR) of both Emitters and Receivers.

The challenge is composed of two phases: 

The evaluation consists of computing the average concordance correlation coefficient (CCC) among the participants tested for the warmth and competence between the predicted continuous values and the continuous ground truth values. 

All participants are invited to submit papers describing their solution to the challenge and following the workshop submission guidelines of the IUI conference.

Examples of potential submissions include (but are not limited to):


The IMPRESSION dataset aims to focus on the development of automatic approaches to study and understand the mechanisms of perception and adaptation to verbal and nonverbal social signals in dyadic interactions, taking into account individual and dyad characteristics. To the best of our knowledge, there is no similar publicly available, nonacted face-to-face dyadic dataset in the research field in terms of participants, recorded sessions, and continuous impression labels in warmth and competence. Detailed information about the IMPRESSION dataset is provided on the challenge website and in the following paper:
