          Abstract

          We present ongoing work in the development of a novel method for providing tactile feedback by using 3D-printed particle-enhanced soft composites (PESC) that, when compressed, produce a creased surface. By controlling the creasing of the material through 3D-printed rigid structures embedded in the material various textures on the material's surface can be produced. We show, through several iterations, the impact of different 3D-printed designs on the production of textures We discuss limitations and highlight possible application areas in HCI for the proposed approach.

            Creating Realistic Virtual Textures from Contact Acceleration Data.

            Modern haptic interfaces are adept at conveying the large-scale shape of virtual objects, but they often provide unrealistic or no feedback when it comes to the microscopic details of surface texture. Direct texture-rendering challenges the state of the art in haptics because it requires a finely detailed model of the surface's properties, real-time dynamic simulation of complex interactions, and high-bandwidth haptic output to enable the user to feel the resulting contacts. This paper presents a new, fully realized solution for creating realistic virtual textures. Our system employs a sensorized handheld tool to capture the feel of a given texture, recording three-dimensional tool acceleration, tool position, and contact force over time. We reduce the three-dimensional acceleration signals to a perceptually equivalent one-dimensional signal, and then we use linear predictive coding to distill this raw haptic information into a database of frequency-domain texture models. Finally, we render these texture models in real time on a Wacom tablet using a stylus augmented with small voice coil actuators. The resulting virtual textures provide a compelling simulation of contact with the real surfaces, which we verify through a human subject study.
