Grasp Your Potential in the Digital Age
We are an interdisciplinary research group working on human-computer interaction (HCI), multimodal interfaces, image processing, and artificial intelligence (AI). We always provide an open environment and are actively involved in research projects in industry, academia, and the community.

Discover Our Studies
We welcome everyone who is interested in our research topics as a member of our lab. Like "seeing is believing, believing is knowing, knowing is not knowing, and knowing is not knowing" (Thomas Fuller), we work hard to create new things that are not often possible in a small laboratory. Apart from studying, our members also interact with each other at various laboratory events and at camps held during summer and winter breaks.

1. Media Arts & 3D Displays
Back in 2013, Prima Lab's predecessor, the Human Interface Lab (hilab), has been working a lot with OpenCV, Unity, and sensor fusion. As the research interests shifted from 2D to 3D, we also began to create innovative 3D displays. The results of this research include 3D spherical displays, polyhedral displays, and light field displays. As contents, there are various simulators for cars, agricultural machines, and games.
2. AI in Practices
Following the AI boom, we started to introduce AI into our computer vision-related research, which had been mainly based on OpenCV, from 2016. The results include 3D human pose analysis, high-precision automatic pupil extraction, various anomaly detections in food processing, and support for agricultural machinery. Research is currently underway in the development of advanced medical devices and human tracking.
3. Eye Tracking
Our initial interest in eye tracking was to develop a device that would allow eye tracking anywhere. We developed an eye tracking system using WebCam, which is available on all modern PCs and mobile devices. As a result, we were able to implement eye tracking not only on PCs, but also on iPads and other devices. Since then, we have also developed a 3D eye tracking device and a device for testing visual field defects, etc. These developments have resulted in our experience in a wide variety of eye tracking systems.
4. Human Motion & Behavior Analysis
Recent developments have made it possible to easily analyze 3D faces and estimate 3D human pose from camera images. This has inspired us to carry out research on rehabilitation evaluation, quantification of tasks, communication mirroring, and facial expression recognition. Currently, we are also pursuing the evaluation of facial expressions by digital humans.
