In Hamlet on the Holodek Janet Murray states, "The enchantment of the computer creates for us a public space that also feels very private and intimate. In psychological terms, computers are liminal objects, located on the threshold between external reality and our own minds." She further states, "Immersive experiences possess the sensation of being surrounded by a completely other reality, that takes over all of our attention, our whole perceptual apparatus."

With these statements in mind, below are three qualities of liminal or immersive objects/experiences and examples from the web that illustrate these qualities:

ENCYCLOPEDIC
