Abstract
Systems and methods are provided for physiological measurement using: a light emitter, a camera, and one or more processors programmed by executable instructions. The system may access image data from the camera. The image data may represent an eye of a patient. The system may further determine a position at which a sensor should be placed based on the image data, the position determined so as to align the sensor for measuring a signal from the eye. The system may further generate a visual guide regarding positioning of the sensor, the visual guide including an alignment zone that includes the determined position. The system may further cause the light emitter to emit light into the eye and take a physiological measurement using the sensor.
Claims22
A device comprising:
- a light emitter;
- a camera;
- and
- one or more processors programmed by executable instructions to:
- access image data from the camera, the image data representing an eye of a patient;
- determine a position at which a sensor should be placed based on the image data, the position determined so as to align the sensor for measuring a signal from the eye;
- generate a visual guide regarding positioning of the sensor, the visual guide comprising an alignment zone that includes the determined position;
- cause the light emitter to emit light that reaches the eye;
- and
- take measurements using the sensor, the measurements providing a physiological measurement.
