The title of the paper is 'Haptic Texture Recognition System Based on Characteristics of Object Surface Material Using Convolutional Recurrent Neural Network.' It proposes a method to extract local and global features by applying a convolutional recurrent neural network (CRNN)-based feature extractor to a database of haptic vibrations generated by an object using a stylus pen, and to recognize and output which material the object is made of among 50 materials.

By combining Convolutional Neural Networks commonly used in existing deep learning methods with Bidirectional Gated Recurrent Units (BGRU), which show excellent performance in processing time-series data, improved results were obtained.
