An open source Etextile VR glove for real-time manipulation of molecular simulations
share
With VR finding increasing application in scientific research, we are beginning to better understand the domains in which it brings the most benefit, as well as the sorts of gestures which scientific workers find most useful as they navigate simulated virtual spaces. Here we describe an open source Etextile data glove which is designed to facilitate detailed manipulation of 3d objects in VR, enabling scientists to accomplish a range of important molecular research tasks. The gloves are designed to sense when a user pinches together their thumb and index finger, or thumb and middle finger. Pinch detection is achieved by closing a circuit bonded onto the gloves using copper fabric. The circuit is connected to an HTC Vive tracker which is attached to the glove via a 3d printed mount that sits on the back of the hand. This design enables us to achieve good positional tracking of the point at which a pinch takes place. Initial tests show that this glove design is sufficiently accurate and robust to enable scientists to accomplish a range of spatially complicated molecular manipulation tasks (e.g., tying a knot in a simulated biomolecular protein), offering a promising alternative to far more costly commercial VR data gloves which we have found to be unfit for our purposes.
