Science Accessories Corporation (SAC) is a company that made acoustic computer input devices, including the Spacepen.
It started business in 1965.[1]

- Freepoint 3D line of digitizers, which replaced the Sciences Accessories GP-12 3D product line.
Technology[edit]
Science Accessories uses sonic technology and a contact probe to capture surface or positioning information from an object. In effect, it does for solid objects what a 2D digitizing tablet does for drawings. The probe is a hand-held device that has two sound emitters on it that are in a line formation with the tip going through the body of the device.[1]
