What is 3D Unity

A new bimanual interface for kinesthetic manipulation of virtual and real objects, designed as a controller for game-based applications, training-simulations, VR/AR, and mechatronics is presented. The interface combines haptic force feedback with hand- and wrist-driven motion, and biometric feedback, being built around a spring placed between two handles. Its design introduces new degrees of freedom (DOF) in spatial motion control, and features a new hands-linked paradigm, where the spring embodies the physicality of the virtual or real object to be manipulated. The user of the SPR1NG Controller feels as if he/she is actually holding and manipulating three-dimensional objects, where changes in the shape of the spring are intuitively translated into the motion and physical modification of those objects. An example of a serious game software application, Shape Fitter, is described to showcase the new interface and its ability to foster creative game design that promotes decision-making.
