A fiducial marker (AprilTag) is glued to the top of the actuator (see \figref{method/device}) to track the finger pose with a camera (StreamCam, Logitech) which is placed above the experimental setup and capturing \qtyproduct{1280 x 720}{px} images at \qty{60}{\hertz} (see \figref{method/apparatus}).

Our visuo-haptic rendering system, described in \secref{method}, allows free exploration of virtual vibrotactile textures on tangible surfaces directly touched with the bare finger to simulate roughness augmentation, while the visual rendering of the hand and environment can be controlled to be in AR or VR.
