Classification: CPC G | IPC G

Claim 14:
15. An electronic device comprising:
one or more distance sensors;
one or more imaging devices;
a display;
one or more processors; and
one or more computer-readable media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
causing the display to present a first graphical element, the first graphical element representing a target location relative to the electronic device;
determining, using the one or more distance sensors, a vertical location of a portion of a user with respect to the electronic device;
generating, using the one or more imaging devices, image data representing the portion of the user;
analyzing feature data corresponding to the image data to determine a horizontal location of the portion of the user with respect to the electronic device;
causing the display to present a second graphical element along with the first graphical element, the second graphical element representative of the vertical location and the horizontal location;

generating, using the one or more imaging devices, additional image data representing the portion of the user;
analyzing additional feature data corresponding to the additional image data to determine an additional vertical location of the portion of the user relative to the electronic device;
determining that the additional vertical location is less than a threshold distance to the target location; and
authenticating a payment transaction by sending at least one of the second sensor data or feature data to a remote system.
