Last month, we released our Pinch Utilities Module, making it easier to create experiences based on how we naturally use our hands in the real world. Here are six community projects that are using this fundamental interactive building block for 3D creativity, menu design, and godlike solar system powers.



Scott Kuehnert’s Triangulate is an augmented reality art program that lets you fill your space with colorful triangles by pinching them out of the air. Using a Hovercast menu on your left palm, you can toggle passthrough, activate a snap grid, clear the canvas, and more.

Graffiti 3D

Recently updated for Oculus 1.3, Scott’s Graffiti 3D lets you doodle in 3D space with the colors and materials of your choice, now using a core pinch mechanic. You can also use a “crimp” gesture (with your thumb meeting the side of your hand).

Using another Hovercast menu, you can control brush color, size, material (cartoon, metal, porcelain, clay, neon, wireframe), and perform a variety of utility functions (such as export/import meshes, turn on augmented reality mode, undo strokes, and clear the canvas).

Sword Art Online GUI


Inspired by the near-future world of Sword Art Online, this simple tech demo is an experiment in menu design and interactions. One of the options allows you to draw in 3D space, while the menu can be grabbed and moved around the scene.

Notice Me Senpai (aka Sloth)

Fulfill your dream of interacting with the world’s cutest sloth. He reacts to three simple hand gestures – thumbs up, peace sign, and (naturally) the middle finger. Pinch in the air to create drawings for your new friend.

VR Solar System Playground

Imagine having the power to bring planets into existence and fling them into orbit. Shared last month on /r/leapmotion, this video also features an early arm menu.

Draw and Scale

This quick project from Mike Harris combines the move and draw utilities to enable a radical shift in perspective. Draw something that can fit in the palm of your hand, then stretch it out and walk inside your creation.
