SAKAIDA, Rui Associate Professor

Research Projects

My research is based on the theory of social interaction and employs a field-based cognitive science approach. I study communication (interaction) in various fields, analyzing the aspects of "timing" and "encounters" that are shaped between people through language and physical interaction.

Recently, I have been particularly focused on research that clarifies how visually impaired individuals are routinely forced to adapt to visual norms of interaction within human societies that are built and operated based on ocularcentrism.

The appeal of research

By observing the everyday communication that we take for granted, as if looking through a microscope, we can learn how our bodies adapt flexibly to the situation at hand. The insights gained in this way may also provide hints for designing artificial objects and services that are closely integrated into our lives.
