1. An object tracking device, comprising: a camera with a field of view oriented in a first direction; a mirror with a field of reflection oriented in a second direction, such that when an object is in a first region in the field of view of the camera, the camera has a direct view of the object and a reflected view of the object from the mirror; and a processor configured to: receive a first image data set and a second image data set from the camera, wherein the first image data set includes the direct view of the object and the reflected view of the object from the mirror, and wherein the second image data set includes the direct view of the object and the reflected view of the object from the mirror; create a three dimensional representation of the object using at least the first image data set; track motion in three dimensions by tracking allocation on a fingertip of a human hand using at least the second image data set; and attempt to locate the fingertip using the first image data set by calculating at least one of an intersection and a closest approach of a first ray from the camera and a second ray from the mirror, and if an intersection of the first ray and the second ray exist, use the intersection as the location of the fingertip, and if no intersection between the first ray and the second ray exists, estimate the location of the fingertip to be at the center of the shortest straight line connecting the first ray to the second ray.
