A vibrotactile floor for enabling interaction through walking in virtual spaces

In existing virtual environments, conventional ground surfaces often impair a user's sense of immersion due to their static nature. This thesis presents a novel approach to enhance one's sense of presence through a floor interface platform that mimics a variety of ground terrains. The ambi...
