A slipstream Revolution augmented reality glasses, led by Google Glass, another possibility has emerged in prototype phase, to see the detail and 3D objects scheduled for QR codes: augmented reality contact lenses.

AR lenses Sensimed

Among the recent developments around glasses that use technology augmented reality (AR), a new market that to date lead the Google Glass, some research teams have gone beyond prototype lens or lenses augmented reality, an experimental field but continuous progress.

AR LentillèreOne of these developments lenses AR is Imageware, a Japanese prototype that converts the field of eyesight of a user on a screen to see the detail and three-dimensional objects and information programmed with QR codes, which incorporates a sensor within the lens It allows viewing from any angle and in real time.

AR lenses Imageware arise from the collaboration and research of a group of researchers from Japanese, Korean and American universities backed by technology companies like Canon and Samsung, in the first cases.

The prototype incorporates an LED (light emitting diode) in each lens, although the main challenge is the material used, due to the constant contact with the eye, so for your design using a conductive material soft, elastic and of course transparent formed by microwires that are placed between layers of graphene.

AR LentillèreThe results of tests conducted by the multidisciplinary team of researchers is that these types of lenses can be used for about five hours without discomfort to the eye, so far tested only in rabbits.

Otro de los desarrollos punteros en lentes inteligentes es el de la compañía suiza de biotecnología Sensimed, en cuyo grupo de investigación se encuentra Babak Parviz, uno de los referentes del proyecto Google Glass. Estas lentes incorporan sistemas microelectromecánicos (Mems) con sensores, procesadores, fuentes de alimentación, antena inalámbrica, etc.

AR LentillèreSimilarly, the main challenge of this prototype is to eliminate the rigidity of the lenses and discover biocompatible and transparent, able to be sterilized and low cost for future marketing components. This development, whose advances have been published in the scientific journal Journal of Micromechanics and Microengineering, is based on the design of a circuit from a film (first metal and then plastic) of just a few nanometers thick, on which light emitting diodes of a third of a millimeter wide and an electronic circuit are inserted.

lens ARIntegrated in the lens of this prototype, called Contact Lens Display (CLD), multilayer system composed of a liquid crystal layer, polarizing filters to form pixels and a microchip that converts the pixels in letters or signs while another obstacles they have not been able to use the entire surface of the lens as a screen and controlled individually projected pixels.

All these prototypes continue to evolve to mainly achieve a suitable system for the human eye does not suffer and have a complete view of the smart as minimum distance from the cornea image.
