23rd ACM International Conference on Multimodal Interaction


It is official, ICMI will be hybrid. We are so excited to hold the meeting in Montreal with an in-person component. So far we are 315 registrations: 59 In-person, 193 Virtual participants and 63 Workshop only!

Download the ICMI 2021 Booklet (PDF) to learn more about the conference.


We are thrilled to have the opportunity to see you in Montreal. After a survey that most of you have completed, you expressed your desire to meet in-person in Montreal. To accommodate our large community, we are planning for a hybrid conference provided that we have enough registrations from the community for an in-person event. The conference will happen both physically in Montreal in the beautiful Old Port and virtually, giving the opportunity to connect to all of you that won’t be able to make it to Montreal. Please register as soon as possible to help us confirm our in-person plans. The deadline for early registration is September 20. We will confirm our hybrid approach after the early registration after knowing how many people have registered to participate in person. We expect to communicate the final decision on September 21 or before if we reach enough in person registrations before that date. The conference hotel will reimburse any cancelled reservation 72h before the reservation/arrival date without penalty.

The 23rd ACM International Conference on Multimodal Interaction (ICMI 2021) will be held in Montreal, Canada. ICMI is the premier international forum for multidisciplinary research on multimodal human-human and human-computer interaction, interfaces, and system development. The conference focuses on theoretical and empirical foundations, component technologies, and combined multimodal processing techniques that define the field of multimodal interaction analysis, interface design, and system development. ICMI 2021 will feature a single-track main conference which includes: keynote speakers, technical full and short papers (including oral and poster presentations), special sessions, demonstrations, exhibits and doctoral spotlight papers.


Good news! Canada is now open for all non-essential travel, see https://travel.gc.ca/travel-covid/travel-restrictions/wizard-start. We are looking forward to seeing everyone in Montreal this October for ICMI-2021.
