Abstract: An augmented reality system for viewing a static physical object includes a movable unit receiving signals from, a static tracking base station for obtaining the six-dimensional absolute position of the movable unit. The relative position of the movable unit relatively to the static physical object is calculated from the absolute positions of the movable unit and the static physical object. The relative unit-object position is then used for rendering and displaying an augmented image or projecting a virtual object on the static physical object.

Abstract: A user wearing a virtual reality headset and holding a real-world input device, uses a finger to input data into the real-world input device under visual assistance within the virtual world. A corresponding virtual input device is positioned within the virtual world in a position similar to the position of the real-world input device relative to the headset, and a fingertip marker upon an input map of the virtual input device in the virtual world is positioned similar to the position of the real-world user's fingertip relative to the real-world input device, thus providing realistic visual assistance in the virtual world for reaching and stroking the desired key or point on the real-world input device.
