Abstract: According to the invention, there is disclosed a system, method, device and computer readable medium for a user to interact with objects in a virtual environment. The invention includes a gesture controller, associated with an aspect of the user, and operative to generate spatial data corresponding to the position of the aspect of the user. A mobile device processor is operative to receive the spatial data of the gesture controller and to automatically process the spatial data to generate a spatial representation in the virtual environment corresponding to the position of the aspect of the user. Thus, the invention is operative to facilitate the user interacting with the objects in the virtual environment using the spatial representation of the gesture controller based on the position of the aspect of the user.
