In this article, we have given a detailed survey of the conventional as well as the recent progress on 3D hand tracking. We discussed a variety of methods that were used to track the human hand and their advantages with disadvantages. The survey included progress made by the different type of sensors used, model types and the vision-based algorithms used. The major problem at hand is to track the hand in real time with efficient algorithms that do not require heavy computations and expensive resources. Two of the recent papers were seen in detail and both of them do not provide clear answers as to how to solve the occlusion problem or changing backgrounds. The output of these models also do not take the human psychology into account when devising or implementing. In the future, the psychophysical parameters related to human acuity and hand movements could be taken into account and a clear algorithm that can enable one to track the human at a level in which the human perceives their hand in a virtual environment.
