Tactile avatar: Tactile sensing system mimicking human tactile cognition

Tactile avatar is an artificial tactile perception and cognition system used as a surrogate for human tactile cognition with potential to produce smooth or soft and rough tactile sensations by its user. In a new report now published on Advanced Science, researchers used a piezoelectric tactile sensor to record varying physical information including pressure, temperature, hardness, sliding velocity and surface topography. In this work, Kyungsoo Kim and a team of scientists in information and communication engineering, neurology, brain and cognitive sciences in Korea engineered artificial tactile cognition by testing the tactile feelings of human participants to a variety of materials ranging from smooth or soft to rough. To account for the response variation among humans, Kim et al. designed a deep learning structure for personalization through training based on individualized histograms of tactile cognition while recording physical tactile information. The decision error of each avatar system was less than 2% for 42 different types of materials, where tactile data could be measured with 100 trials for each material. The tactile avatar machine categorized new experiences of materials based on the knowledge of the tactile training data to show a high correlation with the specific user's approach. The scientists intend to propose an advanced method with tactile emotional exchange capabilities for advanced digital experiences in electronic devices.
