A '''3D pen''' is a computer input gadget that has [[6DOF]] input and is in the shape of a pen. It has finer control than a typical VR game controller, simply because of the shape. It is also called a '''3D stylus'''.

3D styluses are either mechanically mounted, like gadgets from [[SensAble]], or they are tracked using a tracking system like electromagnetic tracking or SteamVR.

Some 3D stylus systems track the pen mechanically. The pen is connected to a base. These systems have been used in medicine. An example of an application of a mechanically tracked system is the VBLaST virtual surgery simulator.<ref>VBLaST - virtual surgery simulator. HowTechTV.
