Phys.org September 28, 2022 Augmented reality (AR) glass needs to be highly transparent over almost the entire visible spectrum. In traditional AR there is a tradeoff in terms of quality and brightness between the external scene and the contextual information you want to visualize. A team of researchers in the US (Columbia University, City University of New York) has demonstrated nonlocal dielectric metasurfaces in the near-infrared that offer both spatial and spectral control of light, realizing metalenses focusing light exclusively over a narrowband resonance while leaving off-resonant frequencies unaffected. This is made possible by quasi-bound state in the continuum encoded […]

Transhumanism: Where Physical and Digital Worlds Meld
IEEE Spectrum October 3, 2019 According to IEEE Digital Reality Initiative human augmentation and machine augmentation are converging, creating a new symbiotic creature. Some of the indicators are: Digital twins – can be created from anything physical that is wired for data with sensors, including you and me; Smart machines can be made by four types of intelligence – embedded, shared, collective, and emerging; Augmenting humans – physical performance with exoskeletons and smart glasses, advances in prosthetics, are further extensions of our physical and mental abilities. Ethical concerns are likely to arise. It is important to consider the consequences…read more. […]
