1. An apparatus for remote hand control of a computer device, the apparatus comprising: a hand tracker, configured to track movement of a hand of a user of the computer device; an image presenter, associated with said hand tracker, configured to present a first image representative of the hand and a second image to the user, and to move the first image in concert with the tracked movement; and a computer controller, associated with said image presenter and configured to control the computer device in accordance with an interaction between the first image and the second image, thereby allowing the user to control the computer device, by moving the hand for bringing the first image and the second image into said interaction, wherein said hand tracker is further configured to track the movement by detecting a segmentation of a continuous feature in a light pattern projected onto the hand, the light pattern as projected onto a flat surface having said continuous feature in a first direction and being non-continuous in a direction substantially perpendicular to the first direction; and said hand tracker detects segmentation of said continuous feature based on changes in light intensity profiles of reflected light along said continuous feature.
