Bird

A one-handed tool for controlling an arbitrary point in 3D space.

2019-2022

The Bird is a tool for controlling a point in 3D space using one hand, designed primarily for use in virtual reality. The Bird stays directly in front of the user's palm, and can be sent farther away or brought closer by extending and closing the fingers. As with a 2D computer mouse, the pointer finger is reserved for selecting, and its extension is ignored for tracking. The name Bird stems from its similarity to a computer mouse, named for an animal occupying the ground, evolved with the addition of a third degree of freedom into an animal occupying the air.

Code for the most recent version of Bird is free and open source, and available at https://github.com/SackJBones/bird-3d-cursor

Unlike other forms of hand tracking, the bird smoothly controls a point in 3D space, allowing for motions like figure-eights, or placement of objects at arbitrary points in space.
