Query: Augmenting reality: On the shared history of perceptual illusion and
  video projection mapping   Perceptual illusions based on the spatial correspondence between objects and
displayed images have been pursued by artists and scientists since the 15th
century, mastering optics to create crucial techniques as the linear
perspective and devices as the Magic Lantern. Contemporary video projection
mapping inherits and further extends this drive to produce perceptual illusions
in space by incorporating the required real time capabilities for dynamically
superposing the imaginary onto physical objects under fluid real world
conditions. A critical milestone has been reached in the creation of the
technical possibilities for all encompassing, untethered synthetic reality
experiences available to the plain senses, where every surface may act as a
screen and the relation to everyday objects is open to alterations.
