Like many technologies, (visually) augmented reality is moving from the environment, into the hands, on- & into the bodies of end-users. From pilots’ head-up displays, to BMW’s augmented reality windshield and Corning’s augmented windows and glass surfaces, to smartphone apps such as Layar, future envisionings of the technology become increasingly intimate.
Researchers at Washington State University (USA) and Aalto University in Helsinki (Finland) are making headway with the development of active contact lenses with embedded LED microarrays that allow pixels to be superimposed on natural vision. The lenses are powered by gigahertz-range radio-frequency energy from a transmitter nearby.
First experiments with rabbit’s eyes, showed apparently no side-effects. While current models of the lenses been limited to a few pixels, they might not immediately give you “contact lens TV” or Terminator vision, but they could already be used for example to warn the hearing-impaired of certain obstacles. Other possible uses for active lenses include biosensing (e.g. Swiss Sensimed uses them to monitor fluctuations in intraoccular pressure) and drug delivery … perhaps even a fake biometric ID of course.
Browsing the world around you like an IKEA catalog might be a vintage design groupie’s wet dream, but fast-forward and we might just as well see today’s streets filled with individuals texting away at their mobilephones replaced by streetviews of people apathically staring into the void or smiling as they see the ugliness of their surroundings superimposed by surrogate imagery (your own personal visual antidepressives).
A more direct approach, bypassing lenses altogether, is to plug into one’s visual cortex directly. More information passes there than meets the eye. Just imagine …
