Systems and methods for quantifying physiologic tremors for health insights via mobile devices

A system for generating a movement-based biomarker, the system comprising:

• an imaging device configured to generate image data associated with a user;
• and
• a control system communicatively coupled to the imaging device, the control system configured to:
• identify, using the image data, a feature of the user;
• calculate, using the image data associated with the user, locations of the feature of the user over a period of time;
• calculate, using the locations of the feature of the user over the period of time relative to a reference element present in the image data that is separate from the feature, a movement of the feature of the user, wherein the control system utilizes a tracking module configured to estimate micro-distance instability vectors for the movement, and wherein a built-in image stabilizer of the imaging device is disabled during generation of the image data;
• and
• generate, using the movement of the feature of the user, the movement-based biomarker.

A system for generating a movement-based biomarker, the system comprising:

• an imaging device configured to generate image data associated with a user, the image data being reproducible as a series of images;
• and
• a control system communicatively coupled to the imaging device, the control system configured to:
• identify, in each image of the series of images, an eye of the user;
• calculate, for each image of the series of images, a location of the eye of the user;
• calculate, based on the location of the eye of the user relative to a facial landmark reference element in each image of the series of images, a movement of the eye of the user, wherein the control system utilizes a tracking module configured to estimate micro-distance instability vectors for the movement, and wherein a built-in image stabilizer of the imaging device is disabled during generation of the image data;
• and
• generate, based on the movement of the eye of the user, the movement-based biomarker.
