Abstract
Systems and methods are provided for improved visual fiducials and detection. A plurality of high-contrast visual fiducials are disposed within an environment (e.g., a vehicle interior). Each high-contrast visual fiducial comprises a pattern layer disposed on a translucent base, the pattern layer comprising an opaque material with one or more pattern components disposed therein. The high-contrast visual fiducials are configured to enable light to pass through the translucent base and through the one or more pattern components of the pattern layer. One or more wearable devices can be configured to detect light passing through the pattern components, the wearable devices communicatively coupled to a detection system configured to decode the received light pattern.
