20 Claims

1. An electronic device comprising:

one or more distance sensors;

one or more imaging devices;

a display;

one or more network interfaces;

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:

detecting, at a first time and using the one or more distance sensors, a hand located over the electronic device;

causing the display to present a first graphical element indicating a target vertical location and a target horizontal location for positioning the hand over the electronic device;

generating, at a second time and using the one or more distance sensors, first distance data based on a first distance to the hand;

determining, based at least in part on the first distance data, a first vertical location of the hand above the electronic device;

generating, at a third time and using the one or more imaging devices, first image data representing the hand;

analyzing first feature data corresponding to the first image data to determine one or more first attributes associated with the hand;

determining, based at least in part on the one or more first attributes, a first horizontal location of the hand over the electronic device;

determining the first vertical location is more than a first threshold distance to the target vertical location;

determining that the first horizontal location is more than a second threshold distance to the target horizontal location;

causing the display to present, along with the first graphical element, a second graphical element indicating the first vertical location and the first horizontal location;

generating, at a fourth time and using the one or more distance sensors, second distance data based on a second distance to the hand;

determining, based at least in part on the second distance data, a second vertical location of the hand above the electronic device;

generating, at a fourth time and using the one or more imaging devices, second image data representing the hand;

analyzing second feature data corresponding to the second image data to determine one or more second attributes associated with the hand;

determining, based at least in part on the one or more second attributes, a second horizontal location of the hand over the electronic device;

determining that the second vertical location is less than the first threshold distance to the target vertical location;

determining that the second horizontal location is less than the second threshold distance to the target horizontal location; and

authenticating a payment transaction by sending, using the one or more network interfaces, at least one of the second image data or the second feature data to a remote system.
