Preface
Thisvolumecontainsthepaperspresentedduringthe2022SymposiumoftheNorwegian
AI Society (NAIS 2022) that was held at Oslo Metropolitan University (OsloMet), in
Oslo, during May 31 – June 1, 2022, and organized jointly by OsloMet and Simula
Metropolitan(SimulaMet).TheNAISSymposiumwasheldforthefourthtime,andthe
second time since 2010. The previous symposium was held in Trondheim in 2019 as

bringingtogetherresearchersandpractitionersinthefieldofartificialintelligence(AI)
from Norway and Scandinavia to present ongoing work and discuss the future of AI.

co-chair Evi Zouganeli. The first part of the symposium was dedicated to applied AI
and robotics for real-life applications. The first keynote was given by Filippo Sanfil-
ippo, University of Agder, who discussed different technologies, types of robots, and
theirapplicationsincludinginIndustry5.0,wearablerobotics,intelligenthealth,human-
robotinteractionandcollaboration,andsearch-and-rescuescenarios.Thiskeynotewas
theperfectintroductiontothefollowingpitchandpaneldiscussionon“AI-androbotics-
enabled systems – status, barriers, and timeline for deployment in real-life systems”.
The session was introduced by Evi Zouganeli and included three pitch presentations.

discussed having underestimated various technical challenges that may appear trivial
but can delay or even hamper real deployments. Aspects that are trivial for humans
are extremely challenging in artificial systems, where a reliable and safe operation is
requiredinthevicinityofhumans.Explainability,trustworthiness,safety,andregulation
were mentioned as important stepstones. In addition, the discussion touched upon the
effectofAI-uptakeonthejobmarket–ourpanelistsseemedtoagreethatrobotswill

WearegratefultotheNorwegianResearchCouncilforfundingtheevent,whichdid

thehelpofmanycolleagues.WewouldliketothanktheTechnicalProgramCommittee
forreviewingthepapersandgivingfeedbacktotheauthors.TheOrganizingCommittee
from OsloMet and SimulaMet acted, in effect, as the event Program Committee, and
we would like to thank all colleagues for their commitment. We are grateful to the
ArtificialIntelligenceLab,theDepartmentofComputerScience,andtheDepartmentof
Mechanical,Electronics,andChemicalEngineeringatOsloMetforsupportingtheevent.
WealsothanktheCourseandConferenceCentre(KK-senter)andTechnicalSupportat
OsloMetfortheirvaluableassistance.
Lastbutnotleast,wewouldliketothankallparticipantsatthesymposium,including
authors,speakers,keynotespeakers,panelists,andsessionchairs–forpresentingtheir
