Continuous miniaturization in electronics resulted in portable technologies such as tablets and smart phones which have greatly enhanced the life quality of the modern society. However, the discomfort associated with the small display screens of such devices remains. The recently emerging near-to eye (N2E) or head worn displays (HWD), with their potential for providing a large field of view (FOV) while preserving mobility, shine as one of the most promising technologies for the future of human-computer interfaces. However, traditional designs suffer from fundamental optical limitations that mandate a compromise among the most important performance metrics: FOV, resolution and form-factor. The ERC funded Wear3D project conducted in OML precisely targets to overcome those limitations and bring the technology to its ultimate form.  

         Wear3D project identifies holography as the unique technique that will simultaneously enable wide FOV, retinal resolution, natural 3D and eye-glasses form factor. Making use of coherent nature of light, we have been able to develop proof-of-concept demonstrations where the optical architecture merely consists of a point light source and a spatial light modulator placed in front of the eye, providing a wide FOV of 80 degrees, retinal resolution, and natural 3D experience with proper focus cues free of accommodation convergence conflict. Research is ongoing with all pace on spatial light modulators, sensors, CGH computation algorithms, micro-optics and novel optical designs with the goal of bringing the technology into human lives as quickly as possible
