Research Activities

Our laboratory investigates the mechanisms of the human visual system from both psychological and neurophysiological perspectives, applying the acquired knowledge to ergonomics and image engineering. Our comprehensive approach includes analyzing the physical phenomena of light and color that generate image information, conducting psychophysical experiments to measure perceptual and physiological responses to visual stimuli, utilizing non-invasive brain imaging and non-human primate neurophysiology research, as well as undertaking social science experiments on the culture and development of visual communication.

Visual Information and Systems (Prof. Koida)

Research topics

• Light and color perception
• Image information generation process via optical analysis
• Primate visual neurophysiology research

This research field focuses specifically on color vision. We are advancing a comprehensive understanding of color-related phenomena by integrating the analysis of optical processes in the environment, the measurement of perceptual cognition and physiological responses, and neurophysiological measurements in non-human primates. Color vision serves as a crucial cue for object recognition and material identification, while the brightness and vividness of colors are directly linked to human values and preferences. Furthermore, the light and wavelengths produced by lighting environments significantly impact physical and mental health. Through a deeper understanding of this color information processing, our field conducts research aimed at practical applications in visual environment design, including displays, product design, lighting, and eyewear.

Attention and Learning Systems (Prof. Tseng)

Research topics

• Visual attention mechanisms and models
• Multi-sensory perception and learning
• Interpersonal nonverbal communication

My research interests cover the broadly-defined human cognitive functions such as perception, attention, and learning. With psychophysical, neurophysiological, and computational approaches, we try to answer how sensory systems construct a coherent world that we experience and look for applications to enhance human life quality. In particular, I investigate how non-verbal cues (touch, temperature, body motion) integrate across sensory systems to enhance the feeling of co-presence between virtual and real spaces in the next generation tele-communication techniques.
