    Abstract: Systems and methods for blue light adjustment with a wearable display system are provided. Embodiments of the systems and methods for blue light adjustment can include receiving an eye image of an eye exposed to an adjusted level of blue light; detecting a change in a pupillary response by comparison of the received eye image to a first image; determining that the pupillary response corresponds to a biometric characteristic of a human individual; and allowing access to a biometric application based on the pupillary response determination.

    Abstract: A method of synthetic content detection in real-time, from a video input source (100) providing images containing at least one human's body part (comprising the head), implemented as a lightweight deepfake detector with a user interface (10) comprising:
    - obtaining 3D points corresponding to the at least one body part and collecting information of the obtained 3D points (1000, 5000);
    - calculating 3D vectors comprising information of position and movement of the points to detect spatial positions of the body part (1010, 5010);
    - detecting anomalies by comparing the calculated vectors with reference information of the body part stored in matrices and verifying at least one criterion: eye blink from eye detection (500) and/or head pose from 3D projection (1000) of the body part comprising the head;
    - providing in real-time a result (1100, 5100) indicating whether synthetic content is detected in the video based on the detected anomalies and each verified criterion.
