Place: Puebla, Mexico

Dear Colleagues,

We are excited to announce the challenge track for the 2nd Workshop on Multilingual and Multimodal Affective Computing (MMAC 2026), held in conjunction with ACII 2026. Participating teams will have access to the DIEM-A dataset, a unique collection of bodily expressions capturing 12 distinct emotions enacted by 92 performers.

This year's challenge invites you to tackle two exciting tracks:

• Performance Task: Can your model accurately detect which of the 12 specific emotions the performer intended to portray using only their body movements?
• Explainability Task: Show us how your model thinks! We highly encourage teams to analyze and visualize exactly how their models derive specific emotions from body movements.

Accepted system description papers will be published in the ACII 2026 companion proceedings. Furthermore, teams will compete for our Best Performance Award and Best Explainability Award, which will be presented at the concluding workshop.

The challenge is now open for registration, allowing approved teams to access the DIEM-A training data and textual context scenarios. Registration information and more details about the challenge are provided at the workshop website. 

We would appreciate it if you could share this information with contacts and students who may be interested in this challenge.

Best regards,

The MMAC 2026 Organizing Committee
