I read that and it is very informative and well written. (I browsed a few more articles and the most hilarious one was 'people who look EXACTLY the same in every photo)
But back to senses. In my layman's terms I noted to myself that we have external and internal senses. So I am right about that. And any device that would simulate a virtual reality as real as this one would need to trigger all those.
In most of my lucid dreams I don't have a sense of body as I put it. They are mostly visual and audio only, with perhaps a little taste and touch and that is it. However, I did have a very vivid dream once, in which I had propioception and had a full sense of a body, a dream body if you will. When I moved my arms, I knew where they were relative to the rest of my body and even felt like I was straining my muscles with physical effort and things had weight to them when I held them in my hand. Even in the dream I thought to myself, if someone took a brain scan of me right now, it would show the exact same centers of the brain firing and illuminating as if I were doing it in real life. The illusion of the dream was real. (It really makes you think....)
And as for the sense of taste. I've heard other say that dream-food is not the same are real food. You seldom chew it and feel it go down your esophagus. Taste is actually very complex and I am a bit of a foodie and amateur chef. What people forget is that our tongues act like a giant thumb. They detect texture and temperature, and even pain when it comes to spicy food. You can even detect the ph level of food, (acidity). Taste is very complex and the best foods tantalize ALL our senses! (even the internal ones after you eat it). I guess it's no surprise that our bodies would be so focused on food, since it is most basic to our survival.
