BBC: Welcome to the 'metaverse'-2

But while a 'phygital' future sounds like paradise to some, others are more sceptical- they doubt that VR will come true or be useful. 

One such sceptic is technology innovator, Dr. Nicola Millard. For one thing, she doesn't like wearing a VR headset- the heavy helmet and glasses that create virtual reality for the wearer- something she explained to BBC World Service's Tech Tent:

There are some basic things to think about. So, how do we access it? So, the reason, sort of, social networks took off was, we've got mobile technologies that let us it. Now, obviously one of the barriers can be that VR or AR headsests- so VR, I've always been slightly sceptical about. I've called it 'vomity reality' for a while because, frankly, I usually need a bucket somewhere close if you've got a headset on me...and also, do I want to spend vast amounts of time in those rather unwieldy headsets? Now, I know they're talking AR as well and obviously that doesn not necessarily need a headset, but I think we're seeing some quite immersive environments coming out at the moment as well. 

Nicola called VR 'vomity reality' because wearing a headset makes her feel sick, maybe because it's so unwieldy- difficult to move or wear because it's big and heavy. 

She also makes a difference between VR- virtual reality- and AR, which stands for augmented reality- tech which adds to the ordimary physical world by projecting virtual words, pictures and characters, usually by wearing glasses ro with a mobile phone. 

While virtual reality replaces what you hear and see, augmented reality adds to it. Both VR and AR are immersive experiences- they stimulate your senses and surround you so that you feel completely involved in the experience. 

In fact, the experience feels so real that people keep coming back for more. 

Right! In my question I asked, Neil, how many people who try VR for the first time want to try it again. 

I guessed it was about half- 49 percent. Was I right?

You were... wrong, I'm afraid. The correct answer is much higher- 79 percent of people would give VR another try. I suppose because the experience was so immersive- stimulating, surronding and realistic.
