The Workshop

The Latin American research community has been working on proposals for the evolution of audio, video and television services, including interactive media experiences (IMX), mulsemedia, usability, user experience evaluation of IMX, under different service modalities, such as Terrestrial Digital TV, Internet Protocol Television (IPTV), Integrated Broadcast-Broadband systems (IBB), World Wide Web (WWW), Over-the-top services (OTT) and beyond.

Prominent researchers, authors and invited speakers from Latina America will gather during the next ACM IMX 2020 in this special workshop called IMX in Latin America (IMX-LATAM 2020). It will be indeed an excellent opportunity for a joint discussion and for establishing closer relationships that can positively impact the comprehensiveness and diversity of the ACM IMX community.

Come and join us!

IMPORTANT UPDATE: Given the COVID-19 situation, the conference and the workshop will take place in Barcelona (Spain) CYBERSPACE (fully online).
