1. A method comprising: controlling, at an eye tracking device, one or more light sources located within the eye tracking device to synchronize emission of light from the one or more light sources with a timing of image capture by a camera, wherein the controlling further includes filtering the light from the light sources using an infrared (IR) pass filter having an IR passband that prevents IR light outside of the IR passband from entering the camera, and wherein the camera has a field of view that overlaps with a field of emission of the one or more light sources; receiving, at the eye tracking device, an image of a portion of a user captured by the camera, the image including reflections caused by light emitted on the user from the one or more light sources located within the eye tracking device; detecting one or more eye features associated with an eye of the user using the reflections; determining point of regard information using the one or more eye features, the point of regard information indicating a location on a display of a computing device coupled to the eye tracking device at which the user was looking when the image of the portion of the user was taken; and sending the point of regard information to an application capable of performing a subsequent operation using the point of regard information.
