1. A computerized method for detecting seizure symptoms, the method implemented by one or more processors and comprising:

  • receiving, from one or more 3D motion sensors, image data capturing a person;

    establishing a detection zone defining an area or volume around the person, the detection zone being less than an entire area or an entire volume of view of the one or more 3D motion sensors;

    detecting the person has moved based on the image data from one or more 3D motion sensors;

    automatically adjusting the detection zone to maintain the detection zone around the person as the person moves;

    based on the image data from within the detection zone, determining that movement for at least a portion of the person is consistent with a seizure, wherein determining that movement for the at least a portion of the person is consistent with the seizure comprises determining a rate of movement and a duration of movement based on at least two images from the image data received from the one or more 3D motion sensors, and determining a variability of velocity of one or more reference points of the person; and

    communicating a determination that movement of the person is consistent with the seizure.
