Have you ever wondered what it would be like to stand on an asteroid? A rugged terrain of boulders and craters beneath your feed, while the airless sky above you opens onto the star-spangled blackness of space.
It sounds like the opening scene for a science fiction movie. But this month, I met with students on the surface of an asteroid, all without leaving my living room.
The solution to this riddle —as you probably guessed from the title of this article— is virtual reality.
Virtual reality (or VR) allows you to enter a simulated environment. Unlike an image or even a video, VR allows you to look in all directions, move freely and interact with objects to create an immersive experience. An appropriate analogy would be to imagine yourself imported into a computer game.
It is therefore perhaps not surprise that a major application for VR has been the gaming industry. However, interest has recently grown in educational, research and training applications.
The current global pandemic has forced everyone to seek online alternatives for their classes, business meetings and social interactions. But even before this year, the need for alternatives to in-person gatherings was increasing. International conferences are expensive on both the wallet and environment, and susceptible to political friction, all of which undermine the goal of sharing ideas within a field. Meanwhile, experiences such as planetariums and museums are limited in reach to people within comfortable traveling distance.
Standard solutions have included web broadcasts of talks, or interactive meetings via platforms such as Zoom or Google hangouts. But these fail to capture the atmosphere of post-talk discussions that are as productive in a conference as the talks themselves. Similarly, you cannot talk to people individually without arranging a separate meeting.
Virtual reality offers an alternative that is closer to the experience of in-person gatherings, and where disadvantages are off-set with opportunities impossible in a regular meeting.
Imagine teaching a class on the solar system, where you could move your classroom from the baked surface of Mercury, to the sulphuric clouds of Venus and onto the icy moons of Jupiter.… Read more
