Core Concepts
Deep learning model for real-time haptic texture rendering shows promising results in human user study.
Abstract
The content discusses the development and evaluation of a deep learning-based model for real-time haptic texture rendering. It addresses the limitations of current methodologies, such as scalability issues due to developing separate models per texture. The model presented in the article is unified over all materials and uses data from a vision-based tactile sensor to render appropriate surface textures based on user actions in real-time. A multi-part human user study was conducted to evaluate the perceptual performance of the model, showing comparable or better quality than state-of-the-art methods without requiring separate models per texture. The study also assessed the model's capability to generalize to unseen textures using GelSight images, demonstrating its effectiveness in rendering novel materials.

Stats
Adding realistic haptic textures to VR environments requires a model that generalizes to variations of user interaction and existing textures.
The proposed deep learning-based action-conditional model shows high-frequency texture renderings with comparable or better quality than state-of-the-art methods.
The model is capable of rendering previously unseen textures using a single GelSight image.
