An apparatus for remote hand control of a computer device, the apparatus comprising: a hand tracker, configured to track movement of a hand (410;610;710;810) of a user of the computer device; an image presenter, associated with the hand tracker, configured to present a first image representative of the hand (410;610;710;810) 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 the 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 the interaction, wherein the hand tracker is further configured to track the movement of the hand by detecting a segmentation of a continuous feature in a light pattern after reflection from the hand (410;610;710;810), the light pattern projected onto the hand (410;610;710;810) having the continuous feature in a first direction and a non-continuous feature in a direction substantially perpendicular to the first direction, the hand tracker is further configured to track the movement of the hand (410;610;710;810) based on a change in an intensity profile of the light pattern after reflection from the hand (410;610;710;810) along the first direction, and wherein the light pattern projected onto the hand (410;610;710;810) comprises a plurality of stripes arranged substantially in parallel to each other, the hand tracker is further configured to identify in the light pattern after reflection from the hand (410;610;710;810) a cluster of stripe segments created by segmentation of stripes by a palm of the hand (410;610;710;810), and the hand tracker is further configured to track the movement of the hand (410;610;710;810) by tracking the cluster of stripe segments. a hand tracker, configured to track movement of a hand (410;610;710;810) of a user of the computer device; an image presenter, associated with the hand tracker, configured to present a first image representative of the hand (410;610;710;810) 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 the 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 the interaction, wherein the hand tracker is further configured to track the movement of the hand by detecting a segmentation of a continuous feature in a light pattern after reflection from the hand (410;610;710;810), the light pattern projected onto the hand (410;610;710;810) having the continuous feature in a first direction and a non-continuous feature in a direction substantially perpendicular to the first direction, the hand tracker is further configured to track the movement of the hand (410;610;710;810) based on a change in an intensity profile of the light pattern after reflection from the hand (410;610;710;810) along the first direction, and wherein the light pattern projected onto the hand (410;610;710;810) comprises a plurality of stripes arranged substantially in parallel to each other, the hand tracker is further configured to identify in the light pattern after reflection from the hand (410;610;710;810) a cluster of stripe segments created by segmentation of stripes by a palm of the hand (410;610;710;810), and the hand tracker is further configured to track the movement of the hand (410;610;710;810) by tracking the cluster of stripe segments.
