“…Nogle studier gør brug af 360°optagelser af autentisk interaktion, som efterfølgende er blevet redigeret, herunder tilføjelsen af ekstra 2D vinkler (Arents et al, 2021;Harrington et al, 2018) og ekstra billeder (Lanzieri et al, 2021). Et af studierne giver brugeren mulighed for at teleportere mellem de enkelte 360°optagelser, samt tegne i sfaeren (Kalkofen et al, 2020). Afslutningsvis kombinerer Kittel et al (2020) indhold og aktivitet ved at indlejre reflektionsprompte i materialet.…”

“…For langt de fleste studier er der tale om en passiv aktivitet i 360VR, hvor aktive handlinger udføres før og/eller efter 360VR. Kalkofen et al (2020) gør brug af 360VR som del af en forelaesning, hvor underviseren befinder sig i 360VR og de studerende følger med på en flad skaerm. Der er dermed tale om en passiv oplevelse for de studerende.…”

“…4 studier rapporterer at 360VR giver adgang til en praksis, som ellers ville vaere svaer at få adgang til (Curran et al, 2022;Kalkofen et al, 2020;Lanzieri et al, 2021;Shojaei et al, 2021). Modsat 2D-video, giver 360°video mulighed for at deltagerne selv kan rette fokus i 360°sfaeren (Curran et al, 2022;Kosko et al, 2021).…”

Virtual Reality (VR) vinder større og større indpas på tværs af uddannelsesniveauer. De seneste års teknologiske udvikling har endvidere gjort VR mere tilgængelig for uddannelsesinstitutioner – særligt foranlediget af udviklingen af 360°VR (360VR). Med 360VR kan undervisere designe aktiviteter, hvor studerende får adgang til at arbejde med autentisk videomateriale fra praksis – det kunne være pædagoger, lærere, sygeplejersker og læger. Gennem et systematisk review viser vi at særligt kollaborativ læring i 360VR er tæt på ikke eksisterende. Med udgangspunkt i tre pilotforsøg, viser vi hvordan man kan arbejde med at designe for kollaborativ læring i social 360VR. Vores resultater peger på, at kollaborativ læring i social 360VR skal forstås ud fra en anden begrebsramme end traditionel VR. I skiftet fra individuel VR til social VR opstår et behov for andre begreber end ”immersion”, ”interactivity” og ”presence” – og vi forslår at udviklingen tager afsæt i begreber som interaktionelle ressourcer og perspektivtagning.

“…One such method is the use of virtual field trips (VFTs) or virtual laboratories, which have previously been implemented with good results in engineering courses 15–18. In 1,6 engineering students participated in a VFT and a real field trip (RFT) of the same plant successively and answered a survey to see to what extent VFTs could replace RFTs.…”

Technical visits of installations related to course content can support learning, engagement and motivation of engineering students. However, the COVID-19 lockdown has prevented many in-person activities on campuses. In this work, we propose a framework for developing virtual tours, which we applied to replace in-person visits of heating, ventilating and air-conditioning (HVAC) rooms of buildings located on the campus in an HVAC undergraduate course. The virtual tours rely on many pictures taken in the mechanical rooms, as well as on technical drawings and information integrated in the visits. Students were provided in advance with a series of questions which they had to answer by navigating through the virtual tours. A survey allowed to assess what students appreciated and the difficulties that they encountered during the virtual visits. We found that the virtual visits had several advantages compared to in-person visits, such as allowing students to take the tour at their own pace and extending the learning experience to include other features (e.g. reading technical drawings). Different examples and suggestions of improvement are presented in the paper. The tours had a positive impact on students’ learning and engagement, with overall positive feedbacks from the students. The main hurdle encountered by students was the difficulty to locate themselves in the rooms, which we addressed by adding room layouts in the visits.

“…MiReBooks aims to produce a series of Virtual Reality (VR) and Augmented Reality (AR) based interactive mining handbooks as a new digital standard for higher mining education across Europe. Current challenges in mining education are met in an innovative new way, combining classical paper-based teaching materials with MR materials and their transformation into pedagogically and didactically coherent MR handbooks for integrative classroom use [11].…”

Object Pose Detection to Enable 3D Interaction from 2D Equirectangular Images in Mixed Reality Educational Settings

In this paper, we address the challenge of estimating the 6DoF pose of objects in 2D equirectangular images. This solution allows the transition to the objects’ 3D model from their current pose. In particular, it finds application in the educational use of 360° videos, where it enhances the learning experience of students by making it more engaging and immersive due to the possible interaction with 3D virtual models. We developed a general approach usable for any object and shape. The only requirement is to have an accurate CAD model, even without textures of the item, whose pose must be estimated. The developed pipeline has two main steps: vehicle segmentation from the image background and estimation of the vehicle pose. To accomplish the first task, we used deep learning methods, while for the second, we developed a 360° camera simulator in Unity to generate synthetic equirectangular images used for comparison. We conducted our tests using a miniature truck model whose CAD was at our disposal. The developed algorithm was tested using a metrological analysis applied to real data. The results showed a mean difference of 1.5 with a standard deviation of 1 from the ground truth data for rotations, and 1.4 cm with a standard deviation of 1.5 cm for translations over a research range of ±20 and ±20 cm, respectively.
