New VR Technique Responds to Device-Free Nuanced Hand Movements

Researchers from Virginia Tech developed a novel VR technique that responds to speed and magnitude of hand gestures

A team of researchers from Virginia Tech developed Virtual Reality (VR) technique called Force Push. The VR technique gives its users the ability to move faraway objects with ease, nuance, and focus with the help of an approach for remote object manipulation in VR. According to the researchers, the technique is as simple as using subtle hand gestures to push, pull, or twirl objects. Users can use their bare hands with the help of a natural gesture-to-action mapping for manipulating object in a VR setting. The research titled: Force Push: Exploring Expressive Gesture-to-Force Mappings for Remote Object Manipulation in Virtual Reality, was published in the journal Frontiers in ICT on September 28, 2018.

Force Push offers a more physical, nuanced experience as compared to conventional hand controllers allowed in VR. The technique responds to the speed and magnitude of hand gestures in order to accelerate or decelerate objects. Moreover, Push Force allows users to understand intuitively of the object movement. To bestow the ability to respond to nuanced hand movement, the team developed a novel physics-driven algorithms. The researchers dynamically mapped rich features of input gestures to properties of physics-based simulation. This enhanced the interface and made it more controllable in most cases as compared to conventional VR technique.

According to the researchers, Force Push makes it easy for users to apply the gentlest of nudges to an object. The team also stated that the physics-based technique makes Force Push more plausible to offer a realistic experience to users. The team used an Oculus Rift CV1 for display and a Leap Motion was applied for hand tracking in order to perform user experiments. Unity game engine was used to develop the virtual environment and the native physics engine of Unity was used to boost physics-based simulation of the Force Push interface.
