Safety using AR (Augmented Reality) and VR (Virtual Reality) in school.

In view of the growth of the virtual reality and augmented reality, consideration needs to be given to the safety of its use with children, especially within the school environment.

However, before you decide to brand me a 'Luddite' and form a mob to obliterate every piece of electrical gadgetry I have, let me profess that I love technology... the freedoms it allows, the potential for learning, how it can inspire, and how it can allow us to shape our world according to our needs and desires. Despite it having the power to liberate an individual, it also has the ability to confuse, disorientate and, unsupervised, give access to worryingly inappropriate material. I am amazed with the rapid development of AR and VR from competing technologies such as the Microsoft Hololens, Oculus Rift and the Samsung Gear VR, and genuinely believe that they will have a place in revolutionizing the way children are educated in the near future.

Luckey Palmer (creator of the Oculus Rift) said in an article by Johnson (2015) that VR would predominantly be used in gaming in the next two years, and would then expand to become integrated into the mainstream. In a previous post, I indicate the potential benefits of this technology as being a powerful tool for learning within schools. I still do. Although, if Palmer is to be believed, there is a fair amount of time before sophisticated AR and VR enters our schools; before it reaches the classroom, consideration should be given to its effect on the individual user.

Piaget in 1929, believed that very young children find it difficult to distinguish between fantasy and reality, claiming that they do not have this distinction firmly in place until the age of 12. Morison & Gardner, (1978), Flavell, Green & Flavell, (1986) and Sharon & Woolley, (2004) also agree that:

 "children often err in mistaking non-reality, such as fantasy, appearance, and illusion, for reality" (Woolley & Ghossainy, 2013)

If  this is the case then it could be argued that children between the ages of beginning school and the start of secondary education, may have difficulties in their semantic understanding of AR and VR, If a child cannot understand the difference between reality and alternative realities, then is the use of this technology appropriate? The media in recent years, has been quick to judge (often without evidence) the negative affect that violent computer games and films have on the impressionable, however this technology offers its own set of complications. Films and computer games, although can draw the user in, are not designed to alter the perception of reality: a person playing a computer game, is still aware that they are in their own room, whereas VR and AR are designed to encompass the user in a world which does not exist, or to skew reality. A logical assumption could be that as the user is more intimate with the virtual experience than they are with any other media, then the problems caused by the content (if any) would be greater. Although this theory is flimsy, I am sure it will be tested rigorously by psychologists as the technology becomes more readily available.

In addition, consideration also needs to be given to how children with Special Educational Needs and Disabilities (SEND) interact with AR and VR. For example, those who are on the autistic spectrum, may have difficulty with not only understanding what they perceive to be true but may be distressed due to being overwhelmed by tactile and sensory information, from the mere presence of wearing a headset or having their eyes covered, to sounds that are too loud or are layered over those from the surrounding environment. Equally, the technology should be assessed to see if those with epilepsy can use the equipment safely, without increasing the risk of seizure.

Despite all the concerns surrounding AR and VR, I believe that we should not worry to the extent which Jeff Goldblum's character does in Jurassic Park, prompting thoughts such as:

"Your scientists were so preoccupied with whether they could, that they didn't stop to think if they should."

Woolley & Ghossainy (2013) believe that a  "disproportionate amount of time" has been given to underestimating the accuracy of children to distinguish between the real and the unreal. They believe that children, from the age of 3 can recognise the difference between pretend actions and real ones: eg. pretending to cook using a toy kitchen, or nursing a baby doll. Harris, Pasquini, Duke, Asscher, & Pons, 2006 also argue that most children understand not only tahat physical objects are real, such as a chair or a ball, but things which they cannot see e.g: germs are also real. If this is the case, then the context in which a child learns about their world and the guidance given from adults, is key to their interpretation and cognition. With regards to teaching, educators will require training in how to teach with this new technology and how best to tackle misconceptions incurred from it.

Whereas earlier I have noted potential problems of the use of AR and VR with children with SEND, this technology can be used to allow someone who experiences physical disability, to use an avatar to represent them in a virtual world, who has the same physical capabilities as any other player, regardless of their real world condition. Furthermore, this technology, combined with the right software, could help children who would benefit from sensory integration therapy, as it can let the user experience lights, sound and different visual imagery.

In summary, I believe that AR and VR will be, as Luckey states, integrated into the mainstream, and thus will find a way into education. When it does, as long as it is supported by genuinely inspiring software which motivates students to learn through exploration and creation as well as demonstration, it will be a powerful teaching tool. This article was designed to briefly highlight some unanswered questions regarding potential difficulties with AR and VR being used by children, which during the course of time and the development of the technology, will allow us to better analyse and assess how they react to their use in school.

We exist in a world of technological marvels, where almost anything is possible. We just need to consider how this technology can best support and enrich the life of the user, finding the best way to respond to their needs.

The exciting potential of the Xbox One, Hololens and Minecraft in teaching. Part 1.

I remember when I saw Star Wars (IV A New Hope)  for the first time. I was wide-eyed, young and mesmerised by George Lucas' world of bizarre creatures, Jedi Knights and X-wings. In amongst this iconic cinematography was a scene which was fundamental in shaping my passion for technology and taught a valuable life lesson. It was not the shooting of Greedo the bounty hunter, nor the exploding Death Star but the Holochess game which was played between the meticulously groomed and conditioned: Chewbacca and the bleeping, whistling, childlike droid: R2D2. The game was played on a circular chessboard with the pieces being represented by holograms of animated aliens, which brawled each other when a piece was taken. I thought that this technology was amazing and could only be achieved in a future far, far away. Little did I know, I was witnessing for the first time, what we refer to now as 'augmented reality'; a technology which superimposes a computer generated image on a user's view of the real world, creating a new composite view. However, overshadowing the magic of the special effects was the warning from Han Solo, which still rings as true as it ever did: 'Let the wookie win'.

Today I experienced the same rush of inspiration and wonder which Star Wars had initially conjoured, when I viewed YouTube footage of a particular presentation from E3: the most prestigious gaming expo of the year.

The console: Xbox One.

   The game: Minecraft.

      The new hardware: The Hololens.

After Lydia Winters enthusiastic introduction, the film shows the user wearing the Hololens headset and playing Minecraft on the Xbox One. Instead of playing the game on a traditional monitor, the player, when wearing the device, experiences the game on a virtual screen which appears to be projected on to thin air, in front of them. Impressive? Certainly. Although, as genuinely exciting as this is, it was hard to see beyond the gimmick. Why, when the nation has been conditioned over years to own televisions, would they favour wearing costly cyber specs over the technology they already own?

Arthur C. Clarke once said: 'Any technology that is sufficiently advanced is indistinguishable from magic'. This magic occurred shortly afterwards, when the player stood in front of a square table and cast his spell by saying 'Create World'. Instantly the surface of the table was covered in sand blocks -from within the game- and a fence running around the perimeter. The sand then fell away into a virtual hole, revealing  a 3d, Minecraft world which rose up, out of the tabletop, appearing as though it were a physical model. However this model was animated. Lava flowed, minecarts whizzed around the rails and the player's avatar could be seen jumping and running through the cubic landscape. Equally as impressive, was the ability to see through the walls of built structures, as though the user was a giant peeking through a window, or the way they could see the subterranean chasms underneath the green hills.

Augmented reality, which has been exhibited through silver screen trickery for years (Minority Report, Who Framed Roger Rabbit, Iron man, Avatar etc.) is finally emerging and becoming available to the masses to manipulate and explore games in a new way. It is my opinion this technology could change the way that future generations of pupils access learning, offering exciting possibilities for them to engage with the subject matter. Such as handling virtual artifacts from museums to aid history lessons, exploring a tabletop rainforest to learn about ecosystems or understanding geometry by experimenting within a 3d augmented reality space.  Despite the opportunities this technology offers, it is not without its problems. Although it has been demonstrated at E3, I expect that it, like other devices (Microsoft Kinect, wii  controllers and Playstation's Eye Toy), is not as responsive or as polished as we are led to believe. Equally, as Wheeler (2015) implies in his book: Learning with 'e's, that it would be foolish to suggest that we can educate with these new tools, without adapting the method and practice of teaching. As he states that students are:

'demanding - and expecting - new approaches to learning, approaches that incorporate technology' p.5

Another consideration would be that teachers and children alike, will require training on how to use augmented/virtual reality equipment. This will take a considerable amount of time, time which overworked and overburdened teachers, and over assessed pupils faced with a tightly packed curriculum, do not currently have within the United Kingdom. The final drawback would be the cost of both the hardware and software needed to implement these changes. Luckily, the heavy competition in similar devices to the Hololens could drive the prices down, but thus far, there has been no indication of how much they will sell for. Traditionally, educational software has often been expensive and in my opinion has wildly, varying levels of quality and learning potential; only time will tell whether developers emerge that can create meaningful learning opportunities for students which are also value for money.

The video from the E3 show is available at: https://www.youtube.com/watch?v=xgakdcEzVwg

In my next blog, I shall discuss how the Hololens works in more detail, and in subsequent posts explore and critically analyse the potential for using virtual reality and augmented reality within the classroom.
