1. An apparatus comprising: a plurality of separate image sensors to capture a plurality of images of a user of a display of a computing device from an array of viewpoints included on the display of the computing device, each of the plurality of separate image sensors to capture images of the user from a different viewpoint of the array of viewpoints on the display; a deflector comprising: a first side to deflect light away from each of the array of viewpoints included on the display towards a respective image sensor of the plurality of image sensors, and a second transmissive side, opposite the first side, to allow light from the display to pass through to the user; and logic to: identify an eye of the user in each of the plurality of images captured from the viewpoint associated with each of the plurality of image sensors, determine a gaze direction of the user with respect to the display based, at least in part, on comparison of the identified eye of the user captured in each of the plurality of images, wherein determining the gaze direction of the user includes comparing iris eccentricity of the identified eye of the user captured in each of the plurality of the images of the user to analyze roundness of the iris in each of the plurality of images of the user to determine an image in the plurality of images with less distortion than any other images in the plurality of images as being a viewpoint closest to the gaze direction of the user; determine a target area of the user's gaze on the display based, at least in part, on the determined gaze direction of the user, and execute an application operation in response to determining the target area of the user's gaze.
