What is i-Spy?
i-Spy is an invisible screen for retina of the human eye. You can see the screen normally only by the aid of polarized film. We have initially developed this technology for medical application in ophthalmology in 2011, and have accumulated various experiences at international events such as science workshop, projection mapping and digital signage, since 2012. Now we are going to develop mass production line in our factory to fabricate i-Spy tablets to establish its new market of privacy enhancement for consumers."
