Augmented reality systems

This augmented reality system makes virtual objects appear more realistic when overlaid onto a real-world image. It works by capturing a real-world scene and then calculating the position of its light sources using the image's location, time, and date. Based on this light information, the system generates a realistic shadow for the virtual object, with the claims specifically describing a version that also tracks the camera's orientation to accurately place the virtual object.

Why it matters: Filed before widespread mobile AR. Modern smartphones now integrate high-quality cameras, GPS, and motion sensors, making the required image capture and pose detection readily available.
