INCORPORATING COMPONENTS INSIDE OPTICAL STACKS OF HEAD-MOUNTED DEVICES

摘要: A wearable device includes circuitry on substrate. The substrate is coupled to an optical element in stack. refractive index of the perceptually matches a component. imperceptible viewer wearing device, despite that has view (or, as example, unobstructed line sight to) viewer's eye. can include camera or emitter, both. captures one more reflections emitter from In specific embodiment, waveguide, Fresnel lenses, lens bend light rays around achieve imperceptibility. alternative be piezoelectric liquid crystal controller, any electronic relevant for device.
