    Introduction to Immersive Realities for Educators Contents 1. Introduction 2. Resources & Examples 3. Recommendations 4. Getting Started 5. VR Applications 6. Recording in VR 7. Using Wander 8. VR Champions 9. FAQs 10. References Introduction How VR In Education Will Change How We Learn And Teach The ever-evolving nature of technology continues to influence teaching and learning. One area where advances have impacted educational settings is immersive technology. Virtual reality (VR) immersive technologies “support the creation of synthetic, highly interactive three dimensional (3D) spatial environments that represent real or non-real situations” (Mikropoulos and Natsis, 2010, p. 769). The usage of virtual reality can be traced to the 1960s when cinematographer and inventor Morton Heiling developed the Sensorama, a machine in which individuals watched a film while experiencing a variety of multi-sensory effects, such as wind and various smells related to the scenery. In the 1980’s VR moved into professional education and training. The integration of VR in higher education became apparent in the 1990’s, and continues to be explored within colleges and universities in the 21st century. Why does it all mean? VR, AR, MR and What Does Immersion Actually Mean? Terms such as "Virtual Reality"(VR), "Augmented Reality" (AR), "Mixed Reality" (MR), and "Immersive Content" are becoming increasingly common in education and are more user-friendly and affordable than ever. Like any other technology, IR is used to introduce, support, or reinforce course learning objectives not unlike a text, film, or field trip to a museum. The major difference is that learning can be much more immersive, interactive and engaging.

  • Using Virtual Reality to Engage and Instruct: a Novel Tool for Outreach and Extension Age Group: All Ages! Dr. Geoffrey Attardo
    Using Virtual Reality to Engage and Instruct: A novel tool for Outreach and Extension Age Group: All Ages! Dr. Geoffrey Attardo Email: [email protected] Assistant Professor Room 37 Briggs Hall Department of Entomology and Nematology University of California, Davis Davis, California 95616 Recent developments in computer and display technologies are providing novel ways to interact with information. One of these innovations is the development of Virtual Reality (VR) hardware. Innovations in hardware and software have made this technology broadly accessible with options ranging from cell phone based VR kits made of cardboard to dedicated headsets driven by computers using powerful graphical hardware. VR based educational experiences provide opportunities to present content in a form where they are experienced in 3 dimensions and are interactive. This is accomplished by placing users in virtual spaces with content of interest and allows for natural interactions where users can physically move within the space and use their hands to directly manipulate/experience content. VR also reduces the impact of external sensory distractions by completely immersing the user in the experience. These interactions are particularly compelling when content that is only observable through a microscope (or not at all) can be made large allowing the user to experience these things at scale. This has great potential for entomological education and outreach as students can experience animated models of insects and arthropods at impossible scales. VR has great potential as a new way to present entomological content including aspects of morphology, physiology, behavior and other aspects of insect biology. This demonstration allows users of all ages to view static and animated 3D models of insects and arthropods in virtual reality.
