Designing Virtual Reality for EducationDesigning Virtual Reality for EducationFarzana LatifUniversity of Sheffield, United KingdomMy name is Farzana Latif and my role if Technology Enhanced Learning Manager at the University of Sheffield.OutlineWhat is VREducational valueDesigning VRExamplesEnabling technologies and their limitationsHorizonWhat is Virtual Reality?A high-end user interface that involves real time simulation and interaction through multiple sensorial channels (vision, taste, smell, touch)Girgorie and Phillipe (2003)Around since the 60sNow, more achievableMany of you will aware of what Virtual Reality is. Girgorie and Phillipe describe it as a real time simulation which allows integration through different sensorial channels. VR is defiantly not a new phenomom, it has been around since the 1960s. Arguably over the last 20 years becoming a more achievable option and thanks to powerful mobile devices, with the supplement of a google cardboard and some headphones most of us can experience VR with technology we already have. In Virtual Reality you are completely immersed in a digital environment. This is different to Augmented Reality where digital media is imposed on the world around you. This is shown on this mixed reality continuum. I think its important to make this distinction as in some of the literature I have read the two terms sometime get merged. Examplecombines external devicescollaborativeLooking at some modern examples, we can see how some of the more high end virtual reality combine external devices and enable collaboration. The first picture shows someone experiencing a VR fitness game. Supported by the machines that she is standing on, she feels like she is flying and she is improving her fitness levels at the same time. The next image. The two learners can explore and interact with this 3D model together. (Case Western Reserve, Cleveland Clinic).http://mashable.com/2017/01/12/fitness-vr-gaming-flying/#9_pqMkNyOaq9https://www.youtube.com/watch?v=M4isrqqTlQA ImmersiveHe thought there was a table thereso immersive you can forget where you are VR can be an extremely immersive expereience, Ronnie O Suullival - world snooker champion trying VR snooker, shows just how immersive it can be as he plays VR snooker. The experience is so real that he forgets he is in a Virtual World.https://www.youtube.com/watch?v=OMceVbo3Tm4Educational ValueExperience the Un-ExperienceableHistorical, Scientific, MedicalInaccessible placesView from a different perspectiveOrientationsEnvironmental ObservationsImmersive StorytellingSimulated Practice Training to operate complex machinery Dalgarno and Lee (2010)inside the human bodyDesigning for LearningIntended Learning OutcomesAchieved Learning OutcomesEmpathyReificationIdentificationConceptualisation ConstructionDialoguePresenceIdentityCo-PresenceRepresentational Fidelity Learner InteractionLearning RequirementTaskAffordancesLearning Specificationadapted from Fowler 2014pedagogical benefitstechnology benefitslearning experiencepsychological experienceThis model is developed by Fowler and is focused on designing 3D Virtual Learning Environments and is derived from the work of others. outlines the importance of learning valuesleft hand side helps us think about the pedagogical benefitsthese map onto the learning and psychological immersive experiences the right hand side focuses on what the technology itself can offer and enables us to think about how we can achieve this. Representational fidelity - how realistic the scene is, not just how real. One risk with high-fidelity 3-D VLEs is that they will be used to create virtual classrooms that feel and look like real classrooms but lose the opportunity to create pedagogically new and innovative learning environments. Accessible for AllCreating Simple VR experiences. Easier (in terms of time) to create, inexpensive. More accessible option. Can be created and viewed by all. Capturing real world. Creating advanced VR experiences can take time, requires expert skills (e.g. 3D modelling, coding), costly, inaccessible.focusReusable VR experiences, (e.g. Google Expeditions)A number of out of the box VR solutions exist, examples include Google expeditions, which allows you to be immersed in places all over the world and some educators are sharing the VR experiences, the University of Liverpool in the UK have created VR simulations that take you inside the human body. But the problem with using tools like this is that they aresnt necessarily going to be aligned to your educational scenario. On the other hand to create some of the experiences I have showed so far, takes a lot of skills and require high cost devices. So its not always achievable for everyone. As I mentioned I am going to focus on simple VR experiences. To create our VR experience we will be relying on a 360 camera and web based software to edit and share them. These experiences can be viewed with higher end smart phones (that have a gyroscope and now what direction you are looking) and the relatively cheap Google cardboard. There are many camera, how do they compare: http://www.vrjournalism.io/2016/11/01/360-shootout-camera-comparison/If you cant get access to a 360 camera, try Google Cardboard Camera on your mobile, it stiches photos togetherGoogle cardboard viewersGoing to focus on creating simpler experiences, that offer pedagogic value and will outline tools that can be used to create these experiences.
