1. A computer implemented method comprising: obtaining a time series of images of a hand of a user of a computer device, the hand projected with a light structured in a pattern that enables tracking the hand, the pattern of the structured light comprises a continuous feature in a first direction and a non-continuous feature in a second direction; detecting segmentation of the continuous feature based on changes in intensity profiles of light reflected from the hand along the first direction; tracking a movement of the hand using the images by identifying, in the pattern of the structured light, at least one cluster of continuous feature segments created by the segmentation of the continuous feature by at least one part of the hand and tracking the at least one cluster of continuous feature segments; presenting, on a display of the computer device, a first image representative of the hand and a second image representative of an object of a computer application running on the computer device; moving the first image in concert with the tracked movement of the hand; detecting an interaction between the first image and the second image, the interaction represented by the first image with respect to the second image on the display of the computer device; and invoking a functionality of the computer application based on the detected interaction.
