Special opportunity to attend two back to back conferences June 25-July 2nd 2021 in Greece

We would like to bring to your attention a special opportunity to attend two back to back computer science conferences taking place in two beautiful islands in Greece in June 2021.

  • The 17th International Conference on Artificial Intelligence Applications and Innovations ( AIAI ) on the island of CRETE (June 25-27, 2021) and
  • The 14th International Conference on The PErvasive Technologies Related to Assistive Environments (PETRA ) on the island of CORFU (June 29-July 2nd).
Thus, one could attend both conferences in a period of one week, by flying first to Crete for AIAI and then flying from Crete to Corfu for PETRA, perhaps with a short stopover in Athens!

Coronavirus COVID-19 advisory notices

Dear authors and participants,
We thank you for your interest in Petra 2021, Corfu Island, Greece,  from June 29 to July 2.
While we are excited to hold this year's conference at the beautiful Island of Corfu at the 5-star Hotel Corfu Holiday Palace, we are closely monitoring the disease progression. The conference organizers still plan to hold the conference in hybrid mode and all participants are advised to not book tickets until a final decision will be made by the National Health Organization in Greece as to whether gatherings are allowed in conference rooms due to Covid.

Furthermore, we urge you to proceed with the registration which is the same for virtual and physical presence because the cost of running the conference in hybrid mode is high due to arranging for both physical and virtual conference access. A final decision will be made on April 27.
