Introduction of Human-Computer Interaction Lab

Human-Computer Interaction Lab. (HCI Lab.) is studying computer-based technologies such as virtual reality, graphics, robots, automobiles, and human behavior, cognition, emotion, brain, and biological signals. These studies are proceeding in two major directions. First, we will use HCI or computer technology to study and help people's physical and mental problems. Second, based on the understanding of human beings, we want to study the direction of virtual reality, robot, and automobile technology. These two directions ultimately interact with each other, and we want to carry out research that technology can heal humans, and human understanding can recreate the value of technology.

Research Area

The main research area includes virtual reality technologies, motion-capture, eye-tracking and human interaction system

Direction I : From Techonology to Human

The first example of helping humans with technology is VR-based patient research. We observed patient behavior through a virtual reality-based platform and analyzed behavior patterns to identify patients with obsessive-compulsive disorder. This platform is helpful in diagnosing patients and can be used to see the progress of existing treatment methods such as drug treatment. Furthermore, based on this research experience, we developed software for patient groups with different diseases.We have developed a joint attention program, a representative interaction, to improve the social interaction ability of children with Autism-Spectrum Disorder (ASD). This program was developed using eye/gaze tracking, virtual reality, and virtual avatar. The results of this study are progressing with two potentials for development. First of all, the program is expanding for social and functional training of children with ASD. The expanded program is applied and used in clinical research. Second, clinical experiences in this study are used for the rehabilitation of stroke patients with interaction problems.

Direction II : From Human Factors to Technology

The second direction of our lab is to evaluate human-computer interactio technology and rediscover its value based on understanding of humans. For example, in a VR platform study, desktop, HMD, and cave systems were compared, and in addition to Accuracy and Speed measured in previous studies, Arousal, Valence, Bio-signal, Presence, Simulator Sickness, etc. were measured together.And as a result, it could be verified the advantages and disadvantages of each system, such as the quantitative aspects of emotions caused by the save system and the HMD system are the same, but the qualitative directions are reversed. The results of these studies suggest the direction of interactive media on human emotions and will be able to be used again for technology selection and useful application development.
