Acceptance of an augmented reality system as a visualization tool for computer-aided design classes

This paper presents a study conducted with nineteen students from the Technical University of Catalonia. The study examines user experience and acceptance of an Augmented Reality (AR) system as a visualization tool for Computer-Aided Design (CAD) classes. Although results showed that AR does not improve the learning of CAD techniques, students mentioned that they would find it useful and interesting to continue using AR in CAD lectures. They said that AR helps them to easily understand the forms and volumes of objects and better comprehend the location of objects in the space and its relations with others.Postprint (published version

Using Haar-like feature classifiers for hand tracking in tabletop augmented reality

We propose in this paper a hand interaction approach to Augmented Reality Tabletop applications. We detect the user’s hands using haar-like feature classifiers and correlate its positions with the fixed markers on the table. This gives the user the possibility to move, rotate and resize the virtual objects located over the table with their bare hands.Postprint (published version

Search for a heavy resonance decaying to a pair of vector bosons in the lepton plus merged jet final state root s=13 TeV

A search for a new heavy particle decaying to a pair of vector bosons (WW or WZ) is presented using data from the CMS detector corresponding to an integrated luminosity of 35.9 fb(-1) collected in proton-proton collisions at a centre-of-mass energy of 13 TeV in 2016. One of the bosons is required to be a W boson decaying to e nu or mu nu, while the other boson is required to be reconstructed as a single massive jet with substructure compatible with that of a highly-energetic quark pair from a W or Z boson decay. The search is performed in the resonance mass range between 1.0 and 4.4 TeV. The largest deviation from the background-only hypothesis is observed for a mass near 1.4 TeV and corresponds to a local significance of 2.5 standard deviations. The result is interpreted as an upper bound on the resonance production cross section. Comparing the excluded cross section values and the expectations from theoretical calculations in the bulk graviton and heavy vector triplet models, spin-2 WW resonances with mass smaller than 1.07 TeV and spin-1 WZ resonances lighter than 3.05 TeV, respectively, are excluded at 95% confidence level.Peer reviewe
