GamesBond: Bimanual Haptic Illusion of Physically Connected Objects for Immersive VR Using Grip Deformation
Virtual Reality experiences, such as games and simulations, typically support the usage of bimanual controllers to interact with virtual objects. To recreate the haptic sensation of holding objects of various shapes and behaviors with both hands, previous researchers have used mechanical linkages between the controllers that render adjustable stiffness. However, the linkage cannot quickly adapt to simulate dynamic objects, nor it can be removed to support free movements. This paper introduces GamesBond, a pair of 4-DoF controllers without physical linkage but capable to create the illusion of being connected as a single device, forming a virtual bond. The two controllers work together by dynamically displaying and physically rendering deformations of hand grips, and so allowing users to perceive a single connected object between the hands, such as a jumping rope. With a user study and various applications we show that GamesBond increases the realism, immersion, and enjoyment of bimanual interaction.
GamesBond is the outcome of a recent collaboration between Michel Pahud and Mike Sinclair from Microsoft Research and Andrea Bianchi, associate professor at KAIST and director of the MAKinteract lab, with two of his students, Neung Ryu, the original author of the paper, and Hye-Young Jo. The paper was accepted at ACM CHI Conference on Human Factors in Computing Systems (CHI 2021), where it received an honorable mention award. In this project, we explored a pair of novel 4-DoF controllers, without actual physical linkage between them, that can bend, twist, and stretch together in concert to create the illusion of being connected as a single device with a physical link. Each controller can bend from 0 to 30 degrees in any direction, twist from -70 degrees to 70 degrees and stretch from -2.5mm to 9.0mm (the paper provides all the details of the mechanism).
