This exposition presents the analysis of the successful attempt to apply sensor and control techniques on 3D human computer interfacing for changing 2D visual to 3D visual. The 3D input device virtual reality data glove is used to provide interactivity for handling and manipulating various 3D icons and 3D graphical objects on the computer screen. IT successfully handles the issue related to six degrees of tracking since manipulating 3D objects requires the handling of Six degrees of freedom (DOFs), i.e. three independent axes of movement and three axes of rotation for every object. In the situation of a 2D, the surface limitation does not allow large no of windows and icons to be positioned on the screen whereas in 3D ,the number of windows and icons can be situated top, down, left, right, and even in back surface since the windows are pushed back their appearance is smaller due to perceptive vision. The benefit from the users perspective is that the entire scenario appears to be like a tunnel in which the icons and windows glide in the space as the windows are dragged to for front they turn in to bigger and they pushed back they turn in to smaller. The tunnel shaped desktop generation is elaborated as a two step procedure wherein the data glove captures the data and a 3D WIMP generation takes place. Also a comparative analysis with Compiz Linux, Aero Microsoft vista, Mac Os x Apple, Glass project sun micro, cubic eye and MAW3 is elaborated as a component of the project. Keywords—3 Dimensional Graphical User Interface, WIMP, Perspective Projection, Projection Reference Point, Center of Projection I. INTRODUCTION The research paper works on 3D HCI for changing 2D visual to 3D visual. To provide ―Three Dimensional Interactive Graphical User Interface‖ for Windows Operating System the 5 tunnel desktop interface is very natural and provides more room for placing windows and other graphical objects like icons on the computer screen. The 3D input device virtual reality data glove is used to provide interactivity for handling and manipulating various 3D icons and 3D graphical objects on the computer screen. The mouse is the critical interface to handle 3D graphical objects. Using data glove it‘s possible to put it on like a normal glove and it then acts as an input device that senses finger movements and hand position and orientation (3 coordinates) in real time. II. DESKTOP METAPHOR A desktop environment typically consists of icons, windows, toolbars, folders, wallpapers and desktop widgets A desktop environment aims to be an intuitive way for the user to interact with the computer using concepts which are similar to those used when interacting with the physical world, such as buttons and windows. Perspective projection is a method of representing a 3D object in a 2D image, as it appears from the point of view of an observer. The idea is illustrated in Figure I. To project a 3D object onto a 2D plane, we draw a dotted line between each point on the object and the observer. The location at which the line crosses the projection plane is the position on the plane where the observer perceives the point to be. Figure I: 3D Desktop Manager Generation A. Rationale to prefer Perspective Projection Perspective projection is seeing things larger when they are up close and smaller at a distance. It is a three- dimensional projection of objects on a two-dimensional medium such as paper. The center of projection in a perspective projection is a point which is at a distance from the viewer.
