  • Gaze detection method and apparatus
    Patent number: 11709545
    Abstract: A method for determining if a user's gaze is directed in the direction of a zone of interest in a 3D scene comprises: providing a 3D scene containing a zone of interest; associating a property with the zone of interest; creating a bitmap representing the location of the zone of interest in a projected view of the 3D scene, each pixel of the bitmap to which the zone of interest is projected storing the property of the zone of interest; detecting the direction of the user's gaze; using the bitmap to determine if the detected user's gaze is directed in the direction of the zone of interest.

  • Identification, authentication, and/or guiding of a user using gaze information
    Patent number: 10678897
    Abstract: According to the invention a system for authenticating a user of a device is disclosed. The system may include a first image sensor, a determination unit, and an authentication unit. The first image sensor may be for capturing at least one image of at least part of a user. The determination unit may be for determining information relating to the user's eye based at least in part on at least one image captured by the first image sensor. The authentication unit may be for authenticating the user using the information relating to the user's eye.
