Traditionally direct 3D interaction has always been limited to true 3D devices whereas 2D devices have always been used to achieve indirect 3D interaction. Till date no proper research has been done to try and extend the use of mouse to direct 3D interaction. In this research we explore the issues involved with using the mouse to accommodate the additional degrees of freedom required for 3D interaction. We put forth a unique and innovative design to achieve this objective and show that even a device as simple as the mouse can be highly effective for 3D interaction when supported by an appropriate underlying design. We also discuss in detail a software prototype "Direct3D" that we have developed based on our design and hope to take a step towards making direct 3D interaction easy, inexpensive and available to all computer users.
