Welcome to PETRA 2021

Coronavirus COVID-19 advisory notice

Dear authors and participants,
Thank you for your interest in the Petra 2021 conference, from June 29 to July 1.
The conference organizing committee is still watching the evolution of the COVID-19 pandemic on a daily basis. We would like to thank the authors for the high volume and the high quality of submissions, despite the significant challenges you face.

As you all know, COVID-19 progression has taken a lot of twists and turns and is continuing to mutate and infect many people. In light of the current events around the world, uncertainty around international travel, and many other factors, PETRA 2021 will be completely virtual. We will be using the online platform Underline, where authors can present their work and discuss their results in real-time. We will update you about the platform as soon as we confirm and set it up.


The PErvasive Technologies Related to Assistive Environments (PETRA) conference is a highly interdisciplinary conference that focuses on computational and engineering approaches to improve the quality of life and enhance human performance in a wide range of settings, in the workplace, at home, in public spaces, urban environments, and other. Outcomes of this conference have a broad impact in application areas that include, manufacturing, transportation, healthcare, energy systems, security and safety, robotics, biomedicine, environment and conservation, and many others. PETRA brings together very different types of technologies to also address important social and healthcare issues for sensitive populations, such as the elderly, persons suffering from chronic conditions such as Alzheimer’s, Parkinson’s, Cerebral Palsy, and other disabilities or traumas.

PETRA (which means “stone” in Greek) addresses important human living needs. From a technological perspective, PETRA motivates and inspires new scientific thrusts, innovations and discoveries to improve living environments, a particularly important issue, in an increasingly crowded and complex world where the need for inclusiveness and connectivity with the rest of the world is key. For the elderly in particular, PETRA addresses the fact that, as people grow older; they will increasingly rely on technology to be able to prolong staying in their homes and enjoy an independent life.

The PETRA 2021 proceedings will be published in the ACM Digital Library as part of the ACM ICPS program. The ISBN number assigned to PETRA '21 is 978-1-4503-8792-7
