Our journey into virtual worlds or virtual reality research started in Second Life.
In 2007, we started investigating the role of a three-dimensional (3D) virtual world Second Life in education - and particularly, in supporting our university’s (The Open University, UK) students who study part-time and at a distance. We found Second Life to be useful for running tutorials with our students, for one-to-one meetings with our post-graduate students and for socialisation of students who were new to the university. The educators at our university ‘met’ with educators of other institutions/countries in this environment and learned from one another in the weekly meetings of Virtual Worlds Education Roundtable.
Encouraged by our experiences in Second Life, we embarked on developing a virtual geology field trip for our second level undergraduate students as a part of their Earth Sciences module.
Virtual Skiddaw - a virtual geology field trip
Our students are sometimes unable to participate in field trips due to family constraints or due to health or time constraints. So, we were keen to provide an experience to students as if they have visited Skiddaw mountains in the Lake District. So, with the help of digital photogrammetry and 3D modelling, we have simulated the six sites of the field trip to Skiddaw mountains in this 3D environment. It is an avatar-based environment - it is multi-user - so, students can come together to carry out activities together or the tutor can come in and take them on to a field trip just as our Geologist colleague does in real life. Each avatar has a name that you enter when you log in. You can find out from here where in the six sites each of the avatars are. You can text to one another. So, the tutor can send our messages to students. This environment support individual learning, peer-to-peer learning collaborative learning and tutor-led teaching and learning.
We have not only replicated the six sites of the Skiddaw mountains but we have added features and functionality that may not be possible to experience in real life: for example, draping the maps over mountains - geological map gives an insight into the different rock structures and how they are spread over the land, or bringing up a cross-section to see the geology underneath, or being able to fly and to have a helicopter view of the whole terrain, or being able to teleport to different sites. Each site has activities - so, you can pick up a rock and look at it under the virtual microscope. Virtual microscope is an OU application which is integrated within this Skiddaw app. So, you would normally pick up a rock and take it back to the field centre to study it whereas here our students can look at the rock while they are in the field and on a particular site - so, they learn within the context itself.

Colleagues: Brian Richardson led the production of this app. Tom Argles was our Geologist expert who guided us on how the physical field trip experience could be replicated in a virtual environment.
Smartphone-driven Virtual Reality via 360-degree photospheres and 360-degree videos
We will discuss the next two initiatives of Google Expeditions (360 degree photospheres) and VR via 360 degree videos in our journey of virtual reality in the next blog-post.
