  • Patent number: 10354449
    Abstract: The present invention embraces a system, device, and method for adding lighting effects to augmented reality (AR) content (i.e., virtual objects). Light sensors in an augmented reality (AR) system monitor an environment's lighting conditions to acquire lighting data that can be used to create (or update) virtual light sources. Depth sensors in the AR system sense the environment to acquire mapping data that can be used to create a 3D model of the environment while tracking the system's location within the environment. Algorithms running on a processor may then add the virtual light sources to the 3D model of the environment so that, when AR content is created, lighting effects corresponding to the virtual light sources can be added. The resulting AR content with virtual lighting effects appear more realistic to a user.

    Abstract: A path light that utilizes an ambient light sensor to determine the lighting conditions may experience feedback from its light source if it determines that the lighting conditions are appropriate to illuminate the path light's light source. The path light, as disclosed herein, may compute an offset value to ascertain the amount of feedback from the light source. Upon learning the offset value, the path light may subtract the offset value from a detected amount of light to determine whether the lighting conditions of its surroundings still meet a threshold level of darkness for the path light to illuminate.
