Virtual Reality (VR) is a great tool for revealing this strange and otherworldly foundation of our everyday sensory perceptions.
But you’re seeing your fingers, hearing your fingers, and feeling your fingers-and all of these sensations fully correspond.
Stretch out your hands and snap your fingers. The sense of touch (and indeed, all of our senses) is more or less illusory because no sensation stands alone. 2 pencil, the cool, smooth feel of a chalk-powdered blackboard, the gritty red bricks of the schoolhouse walls. We can all remember the crisply beveled edges of our cheery-yellow No.
