What transitions are there in virtual reality?
As a whole, virtual reality is still a new and emerging medium. There are two main forms of transitions when moving:
- Fly-through transitions (watching the environment move around you) amazes some users but causes motion sickness for others.
- Instant transitions (fade to black) is a new industry trend for movement in VR. Furthermore, instant transitions are available on a wider variety of spaces and perform better on a wider range of hardware.
Matterport's CoreVR system uses instant transitions because they are less likely to cause motion sickness and they are a strong industry trend.
How does virtual reality portray depth?
Similarly, there are two main ways to portray depth in virtual reality:
- Gaze cursor — A grey circle in the middle of the screen that grows when looking at nearby objects and shrinks when looking at distant objects.
- Stereoscopic mode — Two slightly different images for each eye. This is different from monoscopic (the same image for both eyes).
Matterport's CoreVR system uses the gaze cursor because this is usually enough to show depth. Similarly, we use monoscopic views because stereoscopic views require a lot of manual cleanup and can cause motion sickness.
