We present VRSurus, a smart device designed to recognize the puppeteer's gestures and render tactile feedback to enhance the interactivity of physical puppets in virtual reality (VR). VRSurus is wireless, self-contained, and small enough to be mounted upon any physical puppets. Using machine-learning techniques, VRSurus is able to recognize three gestures: swiping, shaking and thrusting. Actuators ({em e.g.,} solenoids, servos and vibration motors) assist with the puppetry visible to the audience and provide tactile feedback on the puppeteer's forearm. As a proof of concept, we implemented a tangible serious VR game using VRSurus that aimed at inspiring children to protect the environment and demonstrated it at the ACM UIST 2015 Student Innovation Contest. Our 3D models, circuitry and the source code are publicly available at www.vrsurus.com at https://github.com/ruofeidu/ninjaterp.
