1. Compact & Slim Tactile Devices  for VR/AR Haptic Glove Interface 

• Participating Project Title: Development of Tactile Standards and High-Fidelity Integrated Haptic Systems for Ultra-Realistic Metaverse Implementation (Organized by: Korea Research Institute of Standards and Science (KRISS) )

• Role of Konkuk University: Development of a soft actuator array that provides holistic tactile feedback to the fingers and palm 

• Collaboration with KAIST and Postech.

In order to provide a sense of reality and immersive tactile feedback in a metaverse environment, we are developing an array-type tactile presentation device that can provide sophisticated tactile sensations to the palm and fingertips.

2. MR Fluid-based haptic System for VR/AR Interface 

• Collaboration with Taxes University at Dallas (Prof. Jin-Ryong Kim Mi-lab   https://mi-lab.io/  )

In order to provide a sense of reality and immersive cutting feeling in a metaverse environment, we are developing an MR fluid based tactile presentation device that can provide sophisticated tactile sutting sensations using haptic scissors interface.

3. Skin-Attachable Haptic Interface 

• Collaboration with Sungkyunkwan Univ., ETRI, UT Dallas and Miami univ.

The market demands and innovation efforts call for a shift in the key VR/AR technologies and engaging people virtually. Tele-haptics with multimodal and bilateral interactions are emerging as the future of the VR/AR industry. By transmitting and receiving haptic sensations wirelessly, tele-haptics allow human-to-human interactions beyond the traditional VR/AR interactions. The core technologies for tele-haptics include multimodal tactile sensing and feedback based on highly advanced sensors and actuators. Recent developments of haptic innovations based on active materials show that active materials can significantly contribute to addressing the needs and challenges for the current and future VR/AR technologies. Accordingly, we are focusing on developing an advanced skin-attachable haptic interface platform based on smart materials such as Electroactive Polymer, Smart Fluid and PZT.
