Force-Directed Graph with the Hover UI Kit
Immerse yourself in an experimental data-viz demo: an interactive, glowing, bouncing, force-directed graph in virtual reality. Your Leap Motion hands can push the graph nodes around and interact with menu interfaces.
The menu interfaces in this demo are powered by Hover UI Kit, a development tool for building beautiful, easy-to-use interfaces for use in VR/AR environments. Hover UI Kit is free for open-source and most non-commercial projects, and can support a variety of different 3D input devices. Check it out for your next VR/AR project!
In this demo, there are two user interfaces:
- Main menu: Open/close this menu by selecting the button in the palm of your left hand. Once open, the menu follows the motion (but not rotation) of your left hand.
- Node menu: Open/close this menu by selecting the button on the front of any node (a sphere in the graph). The node locks into place while the menu is open, so it doesn’t move away from you.
The menu interactions with Hover UI Kit are very simple: move your “cursor” finger very near to a button (or slider handle), and hold it there for a moment. The interactive item fills with a “proximity” color as your cursor approaches it, then the item rapidly fills with a “selection” color once the cursor is close enough. The item selection occurs once the item is filled with the “selection” color.
This demo uses a force-directed graph to visualize data. In this case, the data is generated randomly, but with some more work, the app could be connected to real datasets.
Data visualization in VR/AR is quite exciting, opening up new opportunities for feeling and experiencing the data — not just seeing it. If you’re interested to hear more about this, I often write about it in my blog, and talk about it in my development videos.
This demo is built with the latest “Orion” version from Leap Motion. It supports both Vive and Oculus VR headsets. If a Leap Motion Controller is not detected, the demo automatically switches to use the Vive controllers.
