Drawing of various virtual fixtures that could be overlaid

Virtual Fixtures was a project run by Louis Rosenberg in the year 1992 to create an augmented reality system. It had an overlay of digital 3D information onto a video feed of the real world.

It was originally entirely haptic-focused.

Rosenberg used video cameras and video-passthrough.[1]

Virtual Fixtures used a mechanically tracked 3D handheld input device and a head-fixed display.[2]

The original name of "fixture" was meant to refer to a physical fixture that could guide a surgeon's hand during surgery, to be more precise during an operation.[3]
