Inhabiting a springtail

We want to be able to experience an approximation of what it is like to be a springtail, so we are experimenting with ways to use VR to become one. In virtual reality, avatars are designed to operate human shaped bodies, so we are working to “mis-use” the tools or extend it so it can get us beyond the human.

Luke Stephens is developing a springtail body with a human “skeleton” (animation rig). Then JT Thrash and Shadrick Addy are mapping this rig to the Humanoid Controller SDK (Software Development Kit) in Unity.

The challenges we are encountering are many, including the need to adjust to the differences between the springtail body and the human body. For instance, we lack the antennae, a jumping apparatus (furcula), and extra legs. How do we control all of those extra appendages? Also, should we humans crawl on our hands and feet to conform to the springtail stance? We decided to have the springtail avatar take a human stance, but still include the antennae, furcula, and extra arms/legs.

We will experiment with ways to control these appendages with our body gestures. There was one appendage we did not include on the body, the collophore; a two-part tube that inflates from their abdomen for cleaning and for sticking to surfaces when landing. It looks very challenging to operate a springtail body. Watch the collophore in action in the video below, from the fabulous show Life in the Undergrowth, a BBC series with David Attenborough.
