The research team led by Professor Lee Woo-Gi from the Department of Industrial Engineering at Inha University, along with the Voice AI Research Institute, has developed an artificial intelligence technology capable of recognizing fingertip contact in real time using only standard camera footage.
This technology analyzes depth information and motion information in video simultaneously, enabling accurate recognition of contact even when hands move quickly or are partially occluded.
In particular, it can estimate three-dimensional information using only a standard camera without requiring a separate depth sensor, achieving high recognition performance while reducing costs compared to conventional equipment.
The research was jointly conducted by Professor Lee Woo-Gi’s team, Dr. Mukhiddin Toshpulatov, a visiting researcher at Inha university’s Voice AI Research Institute, and Professor Lee Su-An from Semyung University.
The research results were accepted at CVPR 2026, one of the world’s most prestigious conferences in artificial intelligence and computer vision, under the title “Real-Time Multimodal Fingertip Contact Detection via Depth and Motion Fusion.” Recently, CVPR has recorded an h5-index of 450, demonstrating a level of academic influence ranked second in the world, following Nature and surpassing Science, alongside the rapid advancement of the AI field.
Professor Lee Woo-Gi from the Department of Industrial Engineering stated, “It is significant that performance comparable to existing depth recognition sensors can be achieved using only a simple smartphone camera,” adding, “This technology has strong potential for applications in various fields such as medical simulation, music interfaces, and sign language recognition, and could also serve as a key technology for human-robot collaboration in future smart manufacturing environments.”
Meanwhile, Professor Lee Woo-Gi’s research team has been carrying out the national artificial intelligence core technology development project “XVoice” from 2022 to 2026 with support from the Ministry of Science and ICT, and the research is being conducted with support from the Institute for Information and Communications Technology Planning and Evaluation and the National Research Foundation of Korea.
