A head-mountable device (HMD) is provided for augmenting a contemporaneously viewed “real image” of an object in a real-world environment using a light-field display system that allows for depth and focus discrimination. The HMD may include a light-producing display engine, a viewing location element, and a microlens array. The microlens array may be coupled to the light-producing display engine in a manner such that light emitted from the light-producing display engine is configured to follow an optical path through the microlens array to the viewing location element. The HMD may also include a processor configured to identify a feature of interest in a field-of-view associated with the HMD in an environment, obtain lightfield data, and render, based on the lightfield data, a lightfield that includes a synthetic image related to the feature of interest using depth and focus discrimination. |

1. A head-mountable device (HMD) comprising:
a light-producing display engine; a viewing element; a microlens array coupled to the light-producing display engine in a manner such that light emitted from one or more pixels of the light-producing display engine is configured to follow an optical path through the microlens array to the viewing element; at least one processor coupled to the light-producing display engine; and a storage medium that provides instructions that, when executed by the at least one processor, will cause the HMD to perform operations including:
identifying a first feature of interest in a field-of-view associated with the HMD in an environment, wherein the first feature of interest is associated with a first location and perceived depth to the HMD in the environment, and wherein the first feature of interest is visible at the viewing element;obtaining lightfield data indicative of the environment and the first feature of interest;rendering, based on the lightfield data, a first lightfield comprising a first synthetic image that is related to the first feature of interest at a first focal point that corresponds to the first location and perceived depth for display at the viewing element;identifying a second feature of interest in the field-of-view associated with the HMD in the environment, wherein the second feature of interest is associated with a second location and a second perceived depth to the HMD in the environment, and wherein the second feature of interest is visible at the viewing element;obtaining lightfield data indicative of the environment and the second feature of interest; andrendering, based on the lightfield data, simultaneous to the first lightfield, a second lightfield comprising a second synthetic image that is related to the second feature of interest at a second focal point that corresponds to the second location and perceived depth for display at the viewing element,wherein rendering the first and second lightfields further comprises emitting light from the light-producing display engine along the optical path passing through the microlens array to the viewing element. |
