Lecture 23: Virtual Reality (5)

Can apple vision pro be classified as mixed reality?

@yangbright-2001, I believe since Apple Vision Pro is able to use VR for the screens while also showing the immediate environment due to its outward cameras around these screens, we can consider it to be mixed reality to an extent.

One obstacle of current be is it causes headaches and strain on the eyes, meaning that users cannot use it for extended periods of time. However, it seems that augmented reality dampens this problem, opening more doors for productivity solutions

I am a bit confused about passthrough imaging. I understand that what is being perceived is the real world along with some of the augmented features that the headset provides, however what I do not fully understand is that whether the environment image that is perceived is one that is rendered or do we see stuff actually out in the real world?

What is the difference between mixed reality and augmented reality? Or is mixed reality a version of augmented reality

My understanding is that mixed reality systems allow us to see the real world and computer rendered items and have an interactive experience with both. I think augmented reality just visually adjusts your display. The 2nd lecture seems to describe MR as a mix of AR and VR but I think others refer this combination as just AR

I looked into some of the pros and cons of mixed reality as opposed to augmented reality - it seems like overall mixed reality is more computationally expensive than AR, but can provide a more immersive experience since the all images are captured and processed to appear on a digital screen. On the other hand, while AR is less robust than mixed reality, it has a wide range of practical applications and is generally more accessible (it can be used on a smartphone rather than having to buy another device like VR/MR).

@ttalati, Passthrough in VR means that there is a layer allowing the image of the actual environment captured by camera to be visible, i.e. pass through the virtual scene. This is used in mixed reality because it means we can see both virtual objects and the real world in the background.

We go through the uses for VR in lecture but not many uses for AR/MR. I was wondering how useful they actually are? One use for AR/MR headsets, as seen in the image, is to view displays while completing work. I can see the practical application when trying to complete work as you could, for example, be working on the mechanical components of a car while watching a tutorial on youtube. Similarly you can watch a cooking video while cooking the recipe yourself. However, I don't see the use for MR/AR headsets recreationally as much, as most current applications can also be done with a simpler, and much cheaper, phone or computer. Would AR/MR headsets be used solely for work purposes or could some entertainment uses be made that justify its price?

I've seen mixed usages of the words Augmented Reality and Virtual Reality with respect to passthrough imaging, particularly when the Apple Vision Pro was unveiled. It'd be nice to pin down an exact definition, but intuitively, I feel what Apple has with this passthrough imaging should be classified as purely VR. The important difference is that for AR, the light that's being received is directly from the surroundings, rather than a recreation of it. I remember when the Google Glass was released and found it fascinating as the first mainstream example of AR, but it didn't really pick up then.

I believe it is interesting that we simulate all the scenes in the real world in headset!
