  ACII is the premier international forum for presenting the latest research on
affective computing. In this work, we monitor, quantify and reflect on the
diversity in ACII conference across time by computing a set of indexes. We
measure diversity in terms of gender, geographic location and academia vs
research centres vs industry, and consider three different actors: authors,
keynote speakers and organizers. Results raise awareness on the limited
diversity in the field, in all studied facets, and compared to other AI
conferences. While gender diversity is relatively high, equality is far from
being reached. The community is dominated by European, Asian and North American
researchers, leading the rest of continents under-represented. There is also a
strong absence of companies and research centres focusing on applied research
and products. This study fosters discussion in the community on the need for
diversity and related challenges in terms of minimizing potential biases of the
developed systems to the represented groups. We intend our paper to contribute
with a first analysis to consider as a monitoring tool when implementing
diversity initiatives. The data collected for this study are publicly released
through the European divinAI initiative.
