This class of problems is of utmost importance for robotic manipulation of fluids, for instance, or, in general, in simulation-assisted decision making. The proposed method infers the (linear or non-linear) constitutive behavior of the fluid from video sequences of the sloshing phenomena. Real-time prediction of the fluid response is obtained from a reduced order model (ROM) constructed by means of thermodynamics-informed data-driven learning. From these data, we aim to predict the future response of a twin fluid reacting to the movement of the real container. The constructed system is able to perform accurate forecasts of its future reactions to the movements of the containers. The system is completed with augmented reality techniques, so as to enable comparisons among the predicted result with the actual response of the same liquid and to provide the user with insightful information about the physics taking place. 000095110 536__ $$9info:eu-repo/grantAgreement/ES/DGA/T88$$9info:eu-repo/grantAgreement/ES/MINECO/DPI2017-85139-C2-1-R 000095110 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000095110 590__ $$a3.24$$b2020 000095110 591__ $$aMULTIDISCIPLINARY SCIENCES$$b26 / 73 = 0.356$$c2020$$dQ2$$eT2 000095110 592__ $$a0.99$$b2020 000095110 593__ $$aMultidisciplinary$$c2020$$dQ1 000095110 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000095110 700__ $$0(orcid)0000-0002-9135-866X$$aAlfaro, Iciar$$uUniversidad de Zaragoza 000095110 700__ $$0(orcid)0000-0003-3003-5856$$aGonzalez, David$$uUniversidad de Zaragoza 000095110 700__ $$aChinesta, Francisco 000095110 700__ $$0(orcid)0000-0003-1017-4381$$aCueto, Elías$$uUniversidad de Zaragoza 000095110 7102_ $$15004$$2605$$aUniversidad de Zaragoza$$bDpto.
